[Elecraft] multiband counterpoise with K1. A word of caution

[John Buck]

The suggested Bundle of Counterpoise wires appear to be as set of wires 
closely coupled to each other.  No doubt that it will perform as an 
adequate counterpoise in many cases.

Please note that for multiwire dipoles or antennas connected to the same 
feed line, that spreading the ends of the dipoles enables the wires to 
behave better as resonant antennas.  The point is that the close 
coupling probably does not provide as low an impedance at the desired 
operating frequency as if the ends are fanned out a bit.  The same 
reasoning should apply to the counterpoise where the goal is to provide 
a low impedance at the connection point of the counterpoise to the coax.

So for maximum performance from my QRP rig, I would tend to separate the 
counterpoise wires at least at the far end by a few feet.  Or I would 
use a simple tuner with a single counterpoise wire.  The tuner might be 
smaller than the bundle of extra wire.
