[VHFcontesting] KU4AB 6m Loop vs. PAR Moxon

Many rover stations are using the Par Moxon with good results. It is a 2 element Yagi with the element ends bent toward each other so it "looks like" a loop. The Moxon has gain over a dipole where a single loop has gain LESS than a dipole. The Moxon is probably about 6dB better than a single halo. Of course you have to POINT the Moxon, but unless you're doing a lot of operation while in motion, that's not usually a problem. In either case (halo or Moxon), try to get the the antenna as far off the ground as possible to keep the vertical lobe on the horizon. A 6M antenna at 8 feet has the main lobe pointing way up off the horizon and very little ON the horizon, that's why it works so well on E-skip, especially short skip! I run my 2 element beam at about 16 feet on the rover.. It probably wants more!

After months of waiting, a phone call, and several emails, I gave up and consider my $87 lost. But this provided the opportunity to look into other antennas and came across the PAR Moxon. The company was very responsive and the antenna performs nearly as well as my yagi. Its a bit bigger than the loop might have been, but it fits just fine on the rover mast and has some gain. I have not yet experienced 60mph highway speeds. If anyone has any experience with the PAR 6m Moxon in a rover application I would like to know if it holds up or if I should take the wire and side "sticks" off while traveling.
