As of March January 2013, we are now posting customer comments and photos on Facebook like 'innovantennas' to catch the latest news and reviews! Previous comments below:
I tried the antenna with 4 kW, works very well, 1.2 SWR, fantastic! Saturday, March 9 buy two more for the FM broadcast on different frequencies. thank you very much
- madreceleste - purchased Broadcast band 3el OWL rear mount for 107MHz January 2013
Please see photo below, array sitting at 12.5 mtrs at boom, I will be changing rotators shortly, so as to be able to elevate the array.
I had an opportunity to operate on the weekend for the VHF contest, with a nice contact into Germany with DF5GZ/P.... 70 watts into the array.
Very impressed with the way it's performing so far, I'm receiving the GB3VHF beacon without any issues and have done since the array was mounted on the mast.
I have a couple of recordings of the beacon and so I may well email it to you out of interest, I'll also be in touch about a couple of 70cm Yagis shortly.
Pat MW0XMG - purchased 4 x 6el 144MHz LFAs January 2013
Hi Coley & Justin, Rx'd the 4 element 50MHz LFA-Q today & all looks great. Thanks for all the advice and prompt follow up, you guys have a great business, 73
VK3UDX - purchased 4el 50MHZ LFA-Q January 2013
Review by WB6RTH - Florida USA
It seems like all projects here take about twice as long as expected, but finally the four LFAs are assembled, and all is up on the tower and working.
I have a lot of local noise, but don't have to rotate the azimuth rotator very far before the noise drops way down. Also when I elevate above 20 degrees, the noise completely disappears. That's why I decided on the LFAs, and they sure work as advertised.
I'm happy to report that I made my first two 6 meter EME qsos this morning (with W7GJ and N7NW), very exciting and very satisfying after all the work getting everything ready to go.
I didn't take any pictures during antenna assembly, but quite a few after everything was up on the tower, so am attaching some of them to this email.
Thanks for all your help.
73, Tim - N3XX - Purchased 4 x 7el WOS 50MHz LFA Yagis, splitters and Equip. Summer 2012
The 6 meter 6.8meter LFA antenna is performing very very well, I am hearing stations louder than before and FB ratio is fantastic. Great antenna! Thanks very much for your support for assistance. 73 and Happy Holidays.
WP4O, Ed, EL87rv Tampa Florida - purchased 6el 50MHz LFA summer 2012
Thought you might like to know that the stacked array has now been installed. It is mounted on a 15ft pole, points in a southeasterly direction and is performingly extremely well. The adjustment to the trombones to get a low SWR was minimal and was achieved by pointing the array vertically skywards and it hasn't changed now it is in position, currently reading less than 1.1 around 156 Mc/s.
On the receive side, there is excellent reception across the band from 156 to 162 mc/s with data pulses being heard on 161.975 and 162.025 which are the two channels for AIS. I am about to rig up an AIS Rx using the PC as a chart plotter and will be interested to see whether if I can pick up the off shore stations.
Incidently, I just happened to switch to airband and was surprised to find how good reception is there also.
In short, I'm very happy with the product, both from the quality/performance and also the one to one advice in the first place.
Many thanks and kind regards.
G4YXX, purchased 2 x Marine band 3el LFA Yagis, splitter and cabling August 2012
Hello Justin.........................Just to let you know that the 2m 6ele LFA I ordered has arrived. Just finished putting it together, and it works a treat. Got it on a 10 ft pole at the moment, and on my bird with a 5 watt module, the reflected power is very small, the needle just moves off its stop by a couple of needle widths, so not going to fiddle with it. That was using the 0.870 figure in your docs. QTH only 50ft ASL, but can here now both GB3ANG and GB3VHF. Conditions flat, and would exspect to JUST hear ANG with the existing yagi 20 ft higher, but not VHF.
Geoff, GW3ATZ - purchased 1 x 6el 144MHz LFA September 2012
' I just received a 6 meter 5 element LFA model LFA-VR Yagi (4.35meter boom) last nite which went together just fine.
I wanted to go with one of your 6 element models but the distributor in Ohio only had this model in stock and the price was much to good to not purchase it, plus I need it fast.
All in all I'm glad that I went with the 5 element as it fits my rotation space and works great.
It went together fine and I am now comparing it to an old worn out M2 6M5X that I have had for many years, it does have much lower noise than the M2 does.
The vast majority of my neighborhood noise is down considerably, I can actually point to japan or the pacific and hear quiet now where previously my best low noise direction was to Europe.
Since I'm in the Pacific northwest I have had only one good opening on 6meters DX wise and it was the great June 29th Europe opening of this year.
I wish I had the LFA at that time then maybe I could have made more contacts than I did with my little 35 watt station and the M2 yagi but I didn't know about the LFA design until after the opening the following day when I was listening to my Neighbor, Lew W7EW talking about his stack of LFA's'.
Mike May WB8VLC/7 Salem, Oregon - purchased 1 x 6el 50MHz LFA July 2012
'Justin, hi !!
Installation complete !! Congratulations for your product. Material choice is, indeed, perfect. See http://sv5dkl.blogspot.gr/ , the most recent post, for further details.
Best regards from Rhodes,'
Stathis, SV5DKL - purchased 1 x 4el 50MHz LFA July 2012
'Hi Justin, the array is very quiet compared with my previous (8 x 8wl, US brand) antennas. I hear so much more now and can regularly work into the UK from Croatia.
This system is incredible, thanks so much.'
Zvonko, 9A2AE - purchased 16 x 11el 144MHz LFA Yagi November 2011
'Hello Justin, The IARU 144mhZ contest gave me an opportunity to test out the new LFA yagi.Note: I could NOT use my preamplifier. (developed a fault?) or needs re-aligning. So all the stations worked over past two days is just with the yagi alone and 150W. Receiver DB6NT 144 - TR144 H. Into my Yaesu FT1000MP IF. Coaxial cables heliax FSJ450 Except around the rotor which is Andrews CN-300.
10 countries worked: DL,EA,EI,G,GD,GM,GW,HB9,ON,PA.
Odx 887km HB9EI.
Just picked off the interesting ones a total of 50 contacts only.
The noise floor is quite low, now my QRM problem has gone around -120 to-125 here
(probably not EME standard hi) but I am not pointing at the sky. Front to back
Best rx distance 2227km to beacon in Madeira Island.'
Ralph G4ALY - purchased 1 x 10el 144MHz LFA Yagi August 2012
'I could not have picked a better time for this project, the first week with the antenna has been a week with nice openings on 15 meter. The first 5 days operating the antenna I logged about 60 stations collecting 46 DXCC on all continents including KH2, KH6, 5N, 9M, XE, W6, W7, VU, V8, JA and more....'
'....the InnovAntennas 15 meter OP-DES yagi is well made out of quality material, and it works well.thank you!!'

8P6SH - purchased a 6el 50MHz LFA-LAX - june 2012
'Just worked 6 OK 's a load of HB9's with very flat conditions and the sun noise is very noticeable with the elevation rotator , thou had to download iPhone app to tell me where it was !. With the SSB pre amp I only had the ask very few times for repeated info but got asked several times to repeat mine even running high power. No indicated SWR or reflected power at all...'
'Update antennas are working great heard my CW off the moon after a little trying and without any ground gain. So very pleased. Ps nice to pile ups on 2m aurora again !'

'Antenna working Fantastic!! I cannot measure any reflected power with the Amplifier putting out 160 watts on 144200.00 I have set the dimensions exactly as shown from manual an everything works fine.'
Bruce - N9BX - purchased 1 x 10el 144MHz LFA June 2012
'Good morning Justin, Thank you very much for your last information. It's complete I shall have to adjust the SWR. I shall hold you informed I am anxious to congratulate you also on the excellent mechanical quality of your antennas.
Good luck and, I hope to contact you on the air.'
Marc GREGOIRE - F6GNR - purchased 1 x 13el 144MHz LFA Yagi June 2012
All up and working Justin. Need to trim for SWR (1.3 at mo) due to close proximity of trees. Initial results look very promising. I am changing feeder to LDF450 tomorrow. Will let you know more later in the week.

'Hi Justin, Antennas are working great, SWR 1.1:1 on 432.2MHz ! tnx for test QSO with factory, suprised to hear your 30w. All the best.'
Trevor, G2KF - purchased 2 x 30el 432MHz LFA April 2012
'Hi Justin, Antenna is now working fine. SWR is 1:1.3 from 50.000 to 50.800. Increases fast above 50.800. Not to bad at all with influence of HF antenne, Coax switch and lightning protection taken in account. I have made 1st contact with this antenna with a German station this morning (59 both ways). Heard a Ukranian station yesterday but had no time to work him.
Thanks very much for all the help.' Vy 73 de Pascal – PA1BR purchased 6el 6.8m 50MHz LFA April 2012
With the outer legs fully inserted into the tubes (loop), swr is flat 1:1 from 50001 to someplace near 50500. Amazing. I first thought I was transmitting into a dummy load but I don’t have one that works at 6m. all I need now is some propagation to somewhere. Es season will be kicking off soon, I hope.
Jim N1NK - purchased 4el 50MHz LFA March 2012
73 Andy G0AYZ - purchased a 3el 70MHz OWL Yagi April 2012
Hi Justin, The LFA is really very quiet, I have a SteppIR which has 4 elements on 6m and the antennas do not compare on this band. I have already worked South Africa and Senegal with 100w. Thanks for a great design!
73 Laurent, F8FAZ - purchased a 6el 50Mz 6.4m LFA2 January 2012
Hello Justin, some news: The antenna functions very very well, before I had an antenna I0JXX 16 elements, but in comparison antenna LFA is better, I have much less noise and I hear station that the others of my area do not hear, really it is an excellent antenna,
73 in soon André HB9HLM - purchased 1 x 13el 144MHz LFA Yagi January 2012
'Awesome front to rear ratio, gain seems to be in the same class as the 6M11JKV and SWR is VERY low, below 1.2: from 50.0 - 50.6MHz. The pattern id very clean, no side lobes at all, no back/side lobes. Now for some DX!'
Max DK1MAX - purchased 2 x 6el 5.8m long LFA-MAX Yagis, February 2012
Just an update on the performance of my 4-ele LFA yagi.
I’m amazed that with the antenna mounted barely 5m above ground I managed to work 172 DXCC and 41 NA states. Since last weekend I now have the antenna mounted on a Tennamst at 11m above ground. My 7th contact after mounting the antenna at it’s new height brought me #173, 8R1Z J. All of this from February through to November.
New pics will appear on my website later this week ....http://www.g4ata.co.uk
73 for now Justin
You might be interested to know that there was a lot of interest in what I was doing on the chat board yesterday. You are going to be making a lot of North American bound antennas I believe.
'Hi Justin, I had a quick play, they seem to work well, the noise level is lower than with the Tonnas and listening to PI7CIS they seem to be better, with a more defined peak, but time will tell, there were a few locals chatting on 2m FM from the Leeds area, it was good to be able to completely null them out, so there is definitely better suppression of side lobes.'
Robin G1MHU - purchased 2 x 8el 144MHz LFA January 2012
'Received one of your antennas earlier in the week from Les at ATRC in Sydney. it is a 4el LFA-s 2.8M Boom. I am really impressed with the build quality WOW.'
Andy VK5AKH - purchased 1 x 4el 50MHz LFA January 2012
'During the contest the performance was close to my 8ele at the same height and the antenna busted a lot of piles ups easily. You may be aware that the weather was not exactly good with some quite strong winds.'
Martin G4XUM (MD4K) - purchased a 5 el 28MHz OWA October 2011
as I wrote on my comments on the antenna mechanics I will also give you some info about my operation experience.
After some weeks of operation I am very satisfied with the antennas. I get good reports via moon and at times I could receive my own echoes with -20dB. Also SWR seems to be very stable even under rain (no ice and snow so far, hi). I can really recommend the LFA’s.
Having AZ/EL control for an antenna for the first time EME is real fun now. I had also the luck to contact 8P9MS who worked with a single 14 El. Yagi under rather high degradation.'
73 de Ernst, DK1VI - purchased 4 x 8el LFA for 144MHz Summer 2011
The Array is truly Fabulous. I think I sent you the final SWR measurements a bit ago.
We have had precious little propagation into the west coast so far. There has been no true F2 yet. We've had a smattering of Es links into the F2
from the Southern Pacific areas. Any station that I've heard I've been able to work easily. The T32C and a bunch of VKs have been worked without breaking a sweat.
Typically the locals either don't hear anything or a minimal signal. I hope we get the real F2 in November as The Fabulous LFA Antenna Array will be able to work whatever is out there.'
W7EW, Lew - Installed 6 x 7el50MHzSeptember 2011
‘I just have test the antenne with a staion 40km away. My signal was s9+10 and drop down to 0 on the backside. WOW !!! No side lobs! I have lost many beeps and strange sounds from the area too. ‘
The next day he sent this:
‘VK7AC in pile up no problem! 100w’
PA2DB , Marcus - installed 4el 28MHz LFA October 2011
'Front to Back ratio is FB. A local beacon is 9 +5dB when pointing at it, when I turn away, I can barely here it'
And later in another mail.....
new 4x8 LFA array is up and running! Today I made the first EME QSO and I must admit that performances are astonishing! I got a lot of very loud echoes when Moon was elevated above horizon then, when the Moon was around 5° of elevation, I started to hear very huge echoes with strongest around -7db measured with WSJT and Spectran. Ground gain is a good boost! I kept to get strong echoes even when Moon was already below the horizon so, when the natural satellite was around -1°, I started to call K2ZD who was calling CQ. We completed easily and I received RRR from Mario with my Moon at -2.6° below horizon! I couldn’t believe that! The antenna temperature is really very low and I measured it about 4db better than my previous 4x7 array. The F/B also is superb, around 30db with very clean pattern and low side lobes.
I enclose to this email some pictures of the array.
I’ll keep you informed about the tests I’ll run during next days.
Very ’73 de'

' Not only is the noise level 4 S points lower than on my old antenna, I can now use 4 times as much power as I could with the old system before I see any break-thru on TV or Radio, what a huge difference this makes to my radio life, thank you !!'
Tony, G0MBA - installed 1 x 4el 28MHz LFA Yagi, September 2011
Our second antenna at same height is an M² KT-36XA, a tribander with 5 Elements on 15m. A first longer QSO this evening with a friend who is currently in Namibia V5 brought the result, that the 5 El. LFA is about half an S-Unit louder than the KT-36XA and that result is the same in RX and TX-Mode.
Great, that was what we were hoping, now it is reality'
Wolfgang, DK9VZ - installed 1 x 5el 21MHz LFA Yagi June 2011
I’m sorry to tell you that the antenna is still only about 2 meters from the ground. My neighbour has let me down. He’s a farmer and always very busy.
The test set-up though is doing very well. I have noticed that I get QSOs with quite weak signal stations, that I did not get on the other antenna, so I am glad so far, and I am quite exited to get it up about twelve meters. I will keep you updated on the progress.
Thanks for your Interest.'
73, Sven OZ3SA - purchased 1 x 5el 3.9m 50MHz LFA Yagi June 2011
' ... a friend from the club assembled the antenna for me and commented on how well made it was and the attention to detail. Even down to the countersinking of small hole for certain components. Excellent job and very pleased, my future antennas will be from you.'
Peter G4FPJ - purchased 1 x 6el 144MHz LFA yagi June 2011
Attached a couple of shots when the sun finally came out earlier in the week. I have many more in various lighting and in various states of build/install. All are available in high res (4MB) should you wish to use any I will be more than pleased to supply. Am writing up a review on it so hopefully might see that in some future article. Also included my own VSWR plots using my miniVNA with antenna installed on mast (without any tuning required)
Worked several EU station, one CN and one TF, and heard TY1KS but had to go back to work!!! :-( so couldn't work them...'
Dave M0SAT - purchased 9el 50/70 dualband Yagi July 2011
'After some weekends work the projected 4 x 6 el Yagi Group is now finally up at a height of 24m (top antenna) with a spacing of 1.8 m in H. The antennas having a very good VSWR of 1,02! Also the group sounds very quiet and as calculated. In comparison with the 2x18M2 at 35 m on top of the tower the group has about ~2db less noise floor measured with the Flex 5000 RX spectrum mode. I do now coverage a QTF of 325 to 125 deg for the moment with this very good “2nd antenna” system. So I look forward to work a lots of G´s with this antenna too and I be very curious for the next contests.'

'Tried out the 13 ele 2m LFA yagi in the 2m trophy weekend. Band was deafly quiet (no noise) worked EVERYONE i could hear 1st or 2nd shout, front to back/side is AMAZING!! if your not pointing at them they are not there anymore. Best DX was 830km in flat conditions with 50w, just tuning round to test antenna.

'Been a poor season up here although I was absent during the ST0R opening, and the only day it opened to the mid-west USA. I did however manage to find DU1GM on the 28th June at 0935z.
The 12m LFA has added fire power on that band and year to date has accounted for 133-countries.'
John, G3LZQ - purchased 1 x 12el 10/6m 8.2m long, Duo Bander and 1 x 4el LFA-HD for the 12m band, April 2011
'I got one antenna going last night and the improvement is fantastic. Despite troppo conditions being extremely poor here the past couple of days, I'm hearing beacons now that were completely masked in the local noise before. I'm looking forward to later in the week when EME degradation figures improve so I can give it a go on the moon. Previously I had anything up to an S3 noise level on moonset at times and up to S6 - 7 on moonrise. To the west is now pretty much noise free and to the east, it's just audible, but not enough to move the S-meter. '
Alan adds more....
'...At the weekend (using just one antenna so far), I was extremely pleased to get plenty of decodes from Martin, OK1UGA (4 yagis + 1.5KW) and a number of other stations. Martin peaked at -24dB, which is fantastic considering, even though I only have about 3dB more gain than my old antenna, I couldn't hear any of the 8 or 16 yagi stations previously.
I obviously still have a bit of work in tweaking and improving the system, but these initial results are very encouraging. Being only 2km from the Melbourne central business district, its a glowing testament to the performance of the LFA design to be able to work EME in such a "hostile" environment.'
Alan VK3DXE - purchased 2 x 10el LFA July 2011
'Ciao Justin! At least I managed to install the 10 Lfa.. it's amazing thing ... and it work perfectly. I did some EME QSos... I had before another antenna with the same forward gain but it was impossibile to do EME.. but with the LFA? See the log http://www.qrz.com/db/ik0zyh

'Here's an update on the antenna after one month in Slovakia. It is up and performing well. It is very sturdy and survived a major hailstorm. I have made EME contacts on 6m and have worked the USA and PJ6 on CW and Puerto Rico on SSB. On 4m, I have worked OH9 and made plenty of contacts throughout Europe. My friend 20km away has a 4m dipole, and he says he hears me working stations he cannot copy at all. So I'm satisfied.'

Purchased 1 x 7el 144MHz LFA Yagi February 2011
'I picked up the package and finished the installation of the LFA yagi today. What a difference!!
I could not believe how much less noise and other trash I have now. The F/B is also amazing: pointing at a birdie and turn the back to that position and gone is the birdie. Also the forward gain seems very good and not much difference with the 6M7jhv M2: I can pick up the LX beacon (which I also could with the 6M7jhv) almost permanent but with less noise. I’m impressed. Thanks for a very good product. I’m going to figure out what type of LFA yagi for 70 Mhz can be added to the rest.'
' . . . . The 6m7jhv is ~ 9 meter boom and gain should be 10.3 dBd or so. However the absent of hash and noise (on the LFA) makes it easier to hear weak signals. . . . '
Herewith a picture of the LFA yagi. Fantastic results so far. Worked C5YK and TZ6TR with it. TZ6TR was just above noise level but due to dramatic reduced hash/noise, no problem to copy.
I’m busy with 4 meter setup and need to erect the pipe on the rotator first. I will come back to you what type I decided.'

'The SWR was absolutely spot on with both antennas with no fiddling around to do. All I have to do now is put them to good use. Thanks once again Justin for an producing such an excellent product.'
Yours Sincerely. Phil Dickens.73 G6PHH. 2 x 11el 144MHz LFA Yagis
After replacing 2 x 17el Tonnas with 2 x 11el LFAs Phil was so impressed he bought another 2 x 11el LFAs and went on to say....
So they all seem to working very well Justin.
It was just a shame that there was not a lot of activity on eme today,those there seem to be on 6 meters eme.
But I am well satisfied with your LFA's Justin and they should prove to be a very good improvement to be able to copy lots more weak signals from the moon.'
' .. heard RK3FG today -18dB without the mastpreamp via EME *first reception*YES!! (turned antennas by good luck) Next weekend i finish my digital readout.
I am very happy with your yagi's and alot of people in the club came to see them. Now ON6ZG, ON6NL and me use G0KSC. ON7YT and others want to build LFA yagi's too HI cheers&beers from sunny Belgium.'

'Regarding performance it's a joy. Worked LA2Z with 10W to around 25meters of RG-213 with NO PRE-AMP :) Received him with excellent signal. So what can I say, really impressed as usual. So now I just need the preamp up the mast and some more pwr. Not to mention the 24m mast and three more antennas :)'
