Hmm, you are saying that when you bend over a 1/4 w monopole (which has a rr of
about 30 ohms) about two thirds of the way to the top the rr drops to 7 ohms? 
This is the 80 meter case where 1/4 w is 66 feet, and the wire is vertical for
about 40 feet.

What really interested me was this:  I wanted to make a parallel monopole out of
ladder line, with one conductor 66' and the other 128'.  Then it would be about
a quarter wave on both bands, so it should be resonant on both bands (although
the impedance would be pretty low because of the fold-over).  

I was wondering how the KAT100 would deal with it -- how do I know, for example,
that it would try to match the K2 to the shorter (1/4w) wire on 80 as a low
impedance load and not try to match the almost 1/2 w wire as a high impedance
load?
