Last weekend, 10m was wide open and I made about 40 QSO’s including some very nice exiting new countries. I’m currently using my homebrew rotary dipole for 20 and 10 which is OK, but while I like 10m so much, I’m planning on building a 10m Moxon that uses an “open sleeve” coupling to a 3-element yagi for 6m. Here’s the design I made. The antenna fits on a 2m long boom and is 3,8m wide.
It’s a normal 10m Moxon that I will make from fishing poles with 1,5mm wire. Max gain on 10m is around 11 dBi with a 14 degree angle and F/B ratio of 17 dB. Max gain on 6m is around 12.5 dBi with 8 degree angle and F/B ratio of 21+ dB. Bandwith on both bands is around 500 kHz for SWR better than 1:1.5. The antenna only has ONE feedpoint; the 10m Moxon radiator “couples” the 6m radiator on 50 MHz. Even though I designed this antenna myself, it has been done before by DK7ZB: http://www.qsl.net/dk7zb/Moxon/Dualband-Moxon_10+6m.htm. I’m planning on building this antenne the coming Xmas holidays, will keep you informed about the project!
