[TenTec] Value of RX Only Antennas

I have a K9AY loops system that I bought form Array Solutions. It's 
rather pricey, but for me it was a choice between time and money. I had 
the money, but not the time. I think it cost me between $450 and $500 
but came with everything: mast, wire, control head, preamp -- the works. 
It's well made.

Unfortunately, there's no free lunch: the K9AY loop system is much 
better than my shunt-fed tower on 160 or F12 Sigma 80 OCF 80 m vertical 
dipole and I've truly pulled stuff out using it that I couldn't 
otherwise hear. That said, from everything I've read, it's no Beverage. 
It's utility comes from four significant nulls in cardioid patterns, 
with the nulls oriented N, S, E and W. With these I can decrease QRN 
from distant areas with thunderstorms, which sometimes helps and QRM 
from non-DX directions. It fits easily into a city lot (not really a 
concern for me as I'm in 10 ac) as much as there was no good way to get 
lines out to a Beverage array. I had a way to get lines out to the K9AY 
loops and so that's what I chose.
