Okay, great!
What's a counterpoise wire?
So I need to find a 4:1 balun with a female SMA connector (or the appropriate adapter) to connect to the SDR dongle, and whatever length and AWG size wire for the counterpoise, and that's it?
My current single wire antenna is a 32 foot length of 12AWG wire strung in the attic in a roughly north-south direction. Am contemplating erecting a 25 foot flagpole just outside of an upstairs window and stringing 50 or 60 feet of wire from it to an elevated stanchion in the back yard. With a longer antenna would I need to adjust the length of the counterpoise wire?
I really do appreciate your time and patience.
