An Excellent Dual Band Yagi for 28/50MHz with 11.8m boom
The 28-50-15 Dual Band Yagi has a total of 15 elements, 6 elements are used on 28MHz while 9 elements are used on 50MHz. The 28-50-15 InnovAntennas Dual Band Yagi stands aside from the crowd due to the methods used for its design. No traps or coils and no phasing arrangements are used within this antenna and there is no need for 'compromise' spacing between elements as the antenna has a set of correctly spaced elements for either band but still deploys only one 50 Ohm feed point. An excellent antenna with great SWR bandwidth and performance in one package.
Gain on 28MHz: 11.31dBi @ 28.400MHz
F/B on 28MHz: 22.71dB @ 28.400MHz
Gain on 28MHz at 10m above Ground: 16.17dBi
Gain on 50MHz: 13.01dBi @ 50.150MHz
F/B on 50MHz: 23.05dB @ 50.150MHz
Gain on 50MHz at 10m above Ground: 18.36dBi
Power Rating: 5kw
SWR 28MHz: Below 1.3:1 from 28.00MHz to 28.600MHz
SWR 50MHz: Below 1.3:1 from 50.000MHz to 50.300MHz
Boom Length: 11.9m
Weight: 18.6Kg / 40.9LB
Turning Radius: 5.64m / 18.501ft
Wind Loading: 0.55 Square Metres / 5.9 Square feet
Wind Survival: 163KPH / 101MPH
Other options available if higher wind loading/survival is required.
This antenna deploys 1/2 inch (12.7mm) elements which have 3/8 inch (9.525mm) elements for 50MHz and 5/8 inch elements tapering through 1/2 inch (12.7mm) to 3/8 inch (9.525mm) for 28MHz . The antenna has fully insulated elements which will ensure continuous, high performance for many years to come. Boom to mast brackets are included with all antennas which will support 2 inch (50mm) masts. Boom is 1.75 inch square 10SWG aluminum and a Kevlar boom guy is supplied along with Stainless Steel turnbuckles for adjustment.
Our antennas are constructed with the best quality materials in order that the best mechanical construction can be achieved, not the cheapest and most profitable! Even a digital caliper is used to measure the elements during production to help ensure the best possible results when installed.
Note: much development time has gone into our antennas, not just on basic electromagnetic design, we are able to model the effect of insulators, booms and other objects to ensure the make-up of our antennas has least effect on performance and pattern degradation. More information can be found here
