4/5 (9) el 28/50MHz Yagi (5.2m)

An Excellent Dual Band Yagi for 28/50MHz with 5.2m boom

The 28-50-9 Dual Band Yagi has a total of 9 elements, 4 elements are used on 28MHz while 5 elements are used on 50MHz. The 28-50-9 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.

Specification

This antenna deploys elements tapering from 5/8 inch (15.88mm)  to 3/8 inch (9.525mm)  for  28MHz with elements starting at 1/2 inch (12.7mm)  tapering through 3/8 inch (9.525mm) for 50MHz . 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 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
