Ive been looking at commercially made Moxons ,i usually make my own.I noticed that some have aluminum booms,ive always used fibre glass (not carbon fibre)
Has anyone got an opinion on this ?
Could they be of the plumbers delight variety ? The ones I've made always had a wood boom but they were only small.
Having a metallic boom probably will not be a problem until you get into VHF/UHF. Why anybody would make a Moxon for those bands is beyond me. They may want to experiment or they just need a simple directive antenna. The element lenghts would be altered by the boom if the element went through the boom at VHF/UHF levels. There are plans on the internet for Moxons through the UHF region.
Hope this helps
Hello Barrie; Yes, I'd suggest fiberglass/wood/pvc in that order (instead of metallic) for booms and support arms for best pattern and miminal interaction with the radiating elements.
Fiberglass fishing poles work well in most applications and you can mount them to a sturdy wooden or plastic hub. If you mount the spreaders so they swoop upward the wire elements will be above the "metal clutter" if you opt for a metal hub or angle-sluminum mounting brackets.
Google "The Moxon Antenna Project" for a goldmine of Moxon info; you'll probably be well-inspired, mate.

I have moxons on 20, 17, and 10 meters, all aluminum tubing including the boom. No problems at all. I also have 2 meter moxons but use pvc for the booms on them.
