Greetings all !
I'm looking to put up another longwire after the past years' devastation of
my previous antennae. I've been reading about baluns and matching and am
wondering if they're really needed. Previously I just used the longwire
connected to 50 ohm cable with a ground on the shield. Will a balun make a
difference and is a 1:1 appropriate. Any help is appreciated. Thanks !


There's a huge mismatch except on the frequencies where your wire is
resonant. Those probably total 2 or 3 in the entire HF band.
Otherwise the mismatch will eat most of the signal. Plus, your wire
will be feeding all manner of static electricity into your receiver.
