I plan to build a receive-only longwire/Beverage antenna. The wire will be at least 40m/120' long and strewn at about 7m/21' above ground. Tried "regular" thin insulated wire but it was an eyesore... and the neighbours will probably complain that I'm infecting them with COVID "with your 5G antenna" ha!
Ahem anyway. Considering using monofilar winding wire for stealth purposes :)
What gauge/thickness will still be strong enough mechanically but become virtually invisible against the sky?..
