Re: Loop Question
- I have a K9AY and I love it. I've also used box loops of various
shapes and sizes. The K9AY has a few advantages. First, you can set
it up away from any noise sources and use it remotely. Second, where
a box loop is bi-directional, it is easier to null out stations with
a K9AY, because it's lobe is in one direction. Thirdly, my K9AY does
a great job up to around 9 MHz (tapering off at around 4 MHz and
decreasing in efficiency as you go higher). The box loop is generally
ineffective beyond 1.8 MHz unless you tap the loops etc. If you are
limited to an indoor antenna, a box loop is tough to beat. If you
have the space to put up a K9AY in your yard, the K9AY will amaze you.
ANother alternative is to make a larger remotely tuned multi turn
loop. While they are bi-directional, they offer a lot of gain.
Someday, I'd like to make a 6 or 8 foot remotely tuned loop that will
be mounted in my yard to experiment with. If I am happy with it, I
may phase it against my loops for nulling out my local pests.
