Well you could try adding directors and see how it works, but I'm certain the impedance will be affected and then you'd have something resembling a Yagi/beam, which will go better. The Moxon is basically a modified 2 ele beam, which is supposed to have more gain than a conventional 2 ele beam. So you get the most gain for the amount of elements. Moxons are good for certain applications such as portable setups, indoors, foldback receive antennas, improved handheld performance over a rubber ducky and situations requiring a small "stealth antenna" with big punch and directional qualities. I know a guy who lives on a mountain who has a good signal into VNR08 with a multi element beam. Trouble is, he also hits 08 in Oceanview, off the back of the beam and they get pissed off. He solved the problem using a Moxon pointed at 08.
 So you probably won't win any power battles with one, but they do have their uses and are so easy to build. If you want serious gain, contact Neighbour and get one of his yagis  Good Luck

I got a spare MOXON here now. The uniden handheld it was on past away last night.
 It should fit onto Jennifers radio. DaVo delivery boy,  copy.

Yerrrrrrrrr, she doesn't sound to keen on the idea really. I dunno, i think she can just suffer in the mud for now!! Cant help someone that doesn't want to be helped!! mmmm
 
I was going though the gallery last night and stumbled
onto some of chucky's last Moxon photos ![[Image: moxon_connect_01.jpg]](http://www.goldcoastcb.com/images/moxon_connect_01.jpg) Close up of where the coax joins - gap has to be 5mm Coax connect points don't matter much just as long as there's a good connection. Looks like he used rivets here. ![[Image: moxon_connect_03.jpg]](http://www.goldcoastcb.com/images/moxon_connect_03.jpg) Wider view - alloy frame with plastic cutting board cut into strips screwed in on the inside diameter look to be all that's holding it together firmly. ![[Image: moxon_connect_02.jpg]](http://www.goldcoastcb.com/images/moxon_connect_02.jpg) Notice this alloy frame one is mounted different. All the radiation is pointing upward. The PVC pipe would have to held, or mounted horizontally to a mast. Total cost would be well under $10 Build time about 30 minutes and three beers. As long as the sizes are the same, SWR is real good on CB |
