[Elecraft] KX3 Field Ant. for 80/40/30

[Jim Brown]

Yes, this is also a great technique. One suggestion though -- there's RF 
current in the counterpoise, and having it too close to the ground will 
burn (waste) some TX power. Better to run it in the range of 6-8 ft.

Remember - an SWR indication at the rig is NOT an indicator of antenna 
performance.  It only tells us that the transmitter is matched to 
whatever is connected to its terminals, but it tells us nothing about 
how much power is LOST in the feedline, the antenna, or the ground, nor 
does it tell us how well the antenna radiates or in what directions 
(vertically and horizontally) it radiates.
