Topband: Found my K9AY by WX0B AX-AYl-4 unit

[Peter Bertini]

I will second the need for short radials if your soil is very poor.  I
installed my K9AY system last fall after it sat new and unused in my shed
for a few years.

The first I noticed that it had very poor rejection of distant signals of
the back of the loops.  I added the suggested radials, and noticed a small
improvement. The loops really started to work when I added a cheap CATV
ground rod at the end of each radial where the loop outer tie down pegs are
located.  I tried adding four more radials, for a total of eight, but if
there was a difference after adding the additional four ground rods it was
not noticeable.
