An Excellent Dual Band Yagi for 50/70MHz with 5.4m boom

The 4-6-12 Dual Band Yagi has a total of 12 elements, 6 elements are used on 70MHz while 6 elements are used on 50MHz. The 4-6-12 InnovAntennas Dual Band Yagi stands aside from the crowd due to the methods used for it's design. The 4-6-12 uses no traps or coils, no phasing arrangements and has 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 feed point. An excellent antenna with great SWR bandwidth and performance in one package.

"I have attached a picture of the 12el Innov yagi for 6 and 4m I took in 2018:

The antenna has worked like a dream over the last 5 years, vswr 1:1 across 6 and 4 even when it rains. Antenna gain is excellent and I have no intentions of changing it for the forseeable future. I have worked many DXCCs with it only using low power  with the antenna doing all the work. It has withstood 100MPH+ winds and survived a house move!

Customer Report ON6ID:

"Hi Justin,

 After two days of work the antenna is installed at 27 meters above ground. SWR is very good both on 6 and 4 meterband. Just waiting now for my first contact with this wonderful antenna.

I am a Optibeam fan but your antenna is regarding mechanical construction at the same level as Optibeam.

I send you some pictures from the antenna installed on a small pole for testing and also at the top of my tower.

It wasn’t 2 days of work to install the antenna but at the same time I did some maintenance on the other antennas.

Greetings from Belgium




"Just checked the swr which seem to be very flat.

From 50.000 MHz till 50.500 MHz the swr is 1.1

From 70.000 MHz till 70.290 MHz 1.1 and from 70.290 till 70.500 MHz 1.2

so for me the antenna is working perfect...

Best 73’s and a nice weekend.

This antenna is made with 1/2 inch (12.7mm) centre elements and 3/8 inch (9.525mm) outer elements (70MHz elements are one piece 1/2 inch). 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 1.5 inch square 16SWG aluminum.

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 (with an accuracy of .01mm) to measure the elements during production to ensure they are within 0.2mm of what they should be, ensuring they work as well as our software model predicts.

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 have least effect on performance and pattern degradation.

  • Original Stauff Insulation clamps
  • Mill finished boom and elements for highest levels of accuracy
