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.

I suggest a ‘W1JR style’ 1:1 balun. Work well and very efficient.
Just my opinion.

I would use anything but a BN-86 balun.

But the THx series uses the older BN86/newer BN4000 units, which are 1:1.

It appears that the balun on my TH-7 has died. Can someone
please tell me if this is a 4:1 balun....the Hygain manual
is silent on this subject as far as I can tell.
thanks, 73, Phil W5BVB
