[TowerTalk] 80M antenna wire size

[dj7ww at t-online.de]

If the radiation resistance is only 20 ohms or less, that 0,05 ohms per
meter might reduce the efficiency significantly.

I'm using #18 solid Copperweld wire from Davis RF for my 160m Inverted-L 
antenna.  It tarnished quickly to a dark brown and is virtually 
invisible.  I'm not even sure I could spot it up in the air if it didn't 
have some dacron line holding it up to tell me where it is.  The DC 
resistance is negligible ... something like 0.05 ohms per meter, I think.

It's amazingly strong, too.
