The next time I experiment with end fed antennas, I want to try 
a matching transformer at the end of the antenna wire of about a 
50:1 matching ratio. That way I will have an impedance in the 
feed line of about 50 ohms and minimize coax loss. Now if I am 
connecting the antenna directly to binding posts on the side of 
the KX(2/3), the loss won't matter. But if I am using a length 
of RG174 for a light weight feed line, the lower loss will be 
very nice.

Adding Don's recommended 0.05 wave length "counterpose" in the 
binding post scenario sounds useful. With a coax feed, the coax 
should perform that function.

Now, where am I all wet?
