With all of this discussion about the Par Electronics stressed moxon
antenna for 6m, a quick google search shows that eople have some webpages
about how they homebrewed their own stressed moxon for 6m, but I never see
the stressed moxon design used for lower bands, like 10 and 15 meters. Is
there a reason why? Seems like this antenna design would be a good way to
make a cheap 10m or 12m antenna and it doesn't require a boom either!
