[50mhz] Who's left making high performance 6M antennas?

[jeremy-ca]

Get a 6 el Cushcraft Boomer, they are fairly cheap on the used market. Dont 
know if still in production.

Then stretch the boom 5" by sliding each section a bit, there is plenty of 
overlap.

Add 2 more elements, adjust the others.

I can provide all the info, plots, etc for a large SASE.

Several were built about 10 years ago after extensively getting familiar 
with YO.

Final result:
13.2 dBi from 50.0 to 50.4
37-42 dB f/r over the same range.

On the air performance is absolutely fantastic, especially for minimizing 
QRN and QRM.

I also modified a pair of Hi Gain 66DX's by adding an element and changing 
element dimensions, etc. Single antenna had 11.9 dBi and ~ 40dB f/r.

Ive also modified the Wilson 8el and both 11 el Telrex of old.

Redesigns of most Cushcraft 6M yagis were also done.
