An Excellent Dual Band Yagi for 50/70MHz with 2.1m boom

The 4-6-8 Dual Band Yagi has a total of 8 elements, 4 elements are used on 70MHz while 4 elements are used on 50MHz. The 4-6-8 InnovAntennas Dual Band Yagi stands aside from the crowd due to the methods used for its design. The 4-6-8 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.



Gain on 50MHz: 8.88dBi @ 50.150MHz

F/B on 50MHz: 15.78dB @ 50.150MHz

Gain on 50MHz at 10m above Ground: 14.43dBi

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 1.25 inch square 16SWGaluminum.


  • Marine grade Stainless Steel Fittings
  • Original Stauff Insulation clamps
  • Mill finished boom and elements for highest levels of accuracy


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.
