What would be the optimum given a 15X15 inch square space?


Hi Bill,


You are already there (or, rather, you are already so close that you
wouldn't be able to tell the difference which would be a circle of 15
inch diameter). Subtended area counts for most.

If yer local to a 50kw station, why do you need an antenna all?

Walt, W2DU


I just use the local 50kw station as a reference. It's hard to see
microvolts from some far away station on a scope, so I just use the
big signals to make comparisons. I can see about 14 stations on a
scope connected directly to the loop, but the amplitudes vary from a
few millivolts to almost a volt.

hook a couple of them up to a rectifier and use them to charge batteries to
power your radio. might as well make some use of that rf that is passing
through you all the time!
