Default power on random wire antenna

Thanks Richard.
Do you know if there is a formula to calculare the max power that a
wire can supports?


Hi Andrea,

No. Not off-hand. I use "wire tables" to reference what is called
"fuse current." This is the current that will burn a wire open. For
a 1mm wire, that would be around 50 to 80 Amperes. Your antenna would
have to be a very small loop to encounter that kind of current. Very
small means less than 0.1 wavelength in diameter. You would encounter
other problems long before the wire would melt.
