[Elecraft] [K2] Tuning a magloop with KAT100

[Fred Jensen]

Don is right of course.  If you want a mag loop to actually act like an 
antenna, it MUST be exactly resonant on your transmit frequency ... 
period.  No antenna "tuners," which have never "tuned an antenna" 
anyway. Bypass the KAT2/KAT100 or whatever.  Tune the mag loop cap to 
1.0:1 ... not 1.5:1 or "close" ... 1.0:1.  The K2 will tell you this. 
That's all you do.

100W into a small mag loop probably exceeds it's ratings by close to an 
order of magnitude, and please don't do it if I'm sitting next to it. 
:-)  These are QRP field antennas.
