I wented to let everyone know that I've succeeded in mating the Moxon
rectangle antenna from the March 2001 RFI receiver project to my Icom
IC-Q7A handitalky. I cobbled up the antenna out of aluminum rod, mounted
it to a board with screw eyes, and threaded the ends of the rod for nuts to
attach the feedline. The resulting antenna resonated at 137 MHz first try,
and has a broad front lobe, fair attentuation off the sides, and a very
narrow cardioid-style notch off the back, all just as advertised.
The only small downside is that the thing is almost too sensitive. Anyone
got any suggestions for a simple non-calibrated attenuator that I could put
between the antenna and the radio to make it work a bit better close in to
the noise source?
