[AMRadio] new antenna and matchbox a bust.

[Brett gazdzinski]

Sounds like an interesting antenna!
I must say, I do not trust baluns at high
swr, high power, or on AM, but you can get lucky.
I heard some people ran fine till the band change went
into effect, and when they slid down the balun caught fire!
