[TowerTalk] Need info on balun for Hygain TH-7DX antenna

[K9MA]

FWIW, I used a BN-86 balun on a TH7 for 30 years at 1.5 kW SSB and CW, 
with no problem at all. I did not operate RTTY or AM. I also never 
accidentally tried to load up the TH7 on 40 meters, which I know will 
destroy a BN-86.

That said, I would replace it with a different kind of balun. It is 
definitely 1:1.

73,
Scott K9MA
