Moxon for 6m

6m Moxon beam (based on https://www.jpole-antenna.com/2014/06/ ... n-antenna/ ) but built inside tubing, elements shortened 5% from plan for "enclosed" velocity factor change. Initially cut a couple of inches too long and trimmed with VNC to center frequency on 51.0MHz. Many Moxons work ok for Field Days etc on just simple low masts, but IMHO, VHF antennas like more height if possible.
This describes an easy construction of a temporary antenna, with tape holding wire elements to plastic tubing. Good, but I wanted something like it but weatherproof, so I put the wire inside the tubing, allowing 5% velocity factor correction .. That's pretty much it.

The EzNec+ predicted polar diagram is:
Various Moxon dimensions can be modeled with MoxGen, a Win app, but also runs well with Linux Wine.
