[OKDXA] SWL Report

[Kim Elmore]

This is interesting: I have a old model of the Array Solutions K9AY loop 
system. It has two loops 90 deg to each other set in NE-SW and NW-SE 
configuration and gives me four directions: SW, NW, NE, SW. It simply 
creates a cardiod null off the back and so isn't terribly directive. It 
does, however, actually have nulls. It's about 100 ft NE of my 80 m F12 
Sigma 80 OCF vertical dipole. It works no miracles and sometimes helps, 
sometimes not, on 80 and 160 m. Like Jeff's, it doesn't cover much real 
estate. I use it because, even though I'm on 10 ac, a high-pressure gas 
pipeline has a good-sized right-of-way pretty much through the middle, 
making Beverages problematic. The K9AY loops I have are certainly NOT 
equivalent t Beverages, but are convenient.

What I have is no longer made, but it sounds like a very similar set-up. 
They break down into pretty small packages, so using it as a DXpedition 
low-band rx antenna is certainly a possibility.
