Hello groupos !

I finished a one turn rectangle antenna today. 23m up and roughly 100 m long, the mismatch is still there, but I get almost 15 Amps into the antenna now at a feedpoint of 6 Ohms.

But I guess we are all at least one order of magnitude low, the usual feeling for power and field strength that we all “grew up” with, is by no means valid down there.

What we need to realize again is the extremely poor efficiency of all of our antennas.

Lets see what comes out of it.

There is always time to switch to watercooled amps and three phase power J

This puts a smile on Mal`s face, I know J
