In reference to the change I made building the vertical dipole for AO-7 Mode A,
I now have a better option that is working out great......the Moxon beam. I
found a calculator for working out the dimensions at:
This website has all sorts of ideas in making this simple antenna.
I just building one to see how well it would work in my situation here, I made
my version using 1/2" PVC for a light weight frame and for the elements, #12
stranded electrical wire, which I zipped tied to the pvc frame. As shown in the
picture, I just mounted it below my Arrow dualband yagi, at an elevation of only
8 ft. Even at this low mounting, and surrounded by homes, I am quite impressed
with this antennas results. I would recommend this antenna to anyone wanting to
try and work Mode A with a low price RX antenna.
