I'm contemplating a balloon-supported vertical where the base will be ~1/4 wave 
above ground. I plan to use two symmetrical 1/4-wave horizontal radials. The 
vertical element will be supported above them. The convenience of being able to 
feed this antenna directly with coax is attractive, but how to discharge static 
build-up? An amp has an rf choke across the output terminal, but that's usually 
out of the circuit on receive. Is one of those old pi-wound 2.5 mH 750-mA 
chokes, connected across the feed point, sufficient?

73,
