Moxon antenna calculator

I raised my antenna to around 10 ft for tuning purposes, and measured the swr to be around 2:1 on each of the 3 bands. However , when I raised it on my mast the SWRs measured were: FOR 14.225 MHZ is 1.0:1. FOR 21.250 MHZ is 1.1:1. FOR 28.50 MHZ is 1.3:1. The SWR measured on the WARC bands are reasonable too..

In this video I show how I made a 20 meter Moxon Antenna for portable operation like POTA or SOTA. Yea I know SOTA might be a stretch for most of us! If you make this antenna for home use, I would beef up the base plate and use a heavier gauge wire 18 -12awg. Also look into some heavier duty fiberglass supports for the spreaders.Co-Phasing. Co-phasing or “stacking” has long been a way to get high gain from antennas. Co-phasing involves placing two (or more!) identical antennas either side-by-side or one over top another (“stacking”) at a certain distance apart (usually a 1/2 Wavelength or more) and feeding the antennas in-phase.The result is 3 db more than just a single antenna. ….

A TV antenna amplifier adds energy to input signals from the TV station broadcast towers the antenna picks up. This strengthens the signals, which can improve the picture and sound quality of those stations on the user’s TV.The dimensions for the antenna were calculated using the free Moxon Antenna Calculator program (available for download from here). I set my frequency to 52 MHz with a wire size of 12mm to represent the 12mm aluminium tubing I was using. The resulting calculation is shown in fig 2a below. Spacing [mm] • Spacing is the Distance from the Boom to the 'Gamma-Match'. • Feeding the Antenna can be done at the Director or at the Reflector. (If you are a HAM): Design and Adjustement is easy, as with the Capacitor you can tune the Resonance by some MHz with no effort. (If you are my boss): Design and Adjustement is very tricky and can ...

Building and experimenting with antennas can be an interesting part of the radio hobby. Here we have collected some links to building instructions for 11m antennas on the Internet. Cut two pieces of wire 53 1/2 inches long (add an extra 1/2 inch or so for connecting the wire to the UHF connector) and one piece of wire 114 inches long. Fashion a 90 degree bend at one end of two shorter pieces at the 12 inch mark. Make a 90 degree bend at 15 1/2 inches on each end of the long piece. Lay the wires on the dry-fit frame and ...For most VHF uses, it is the pattern shape, with its very high front-to-rear ratio, that holds more interest than the antenna's gain. Fig. A shows the azimuth pattern of a 2-meter Moxon when the antenna is vertically oriented and, hence, vertically polarized. Patterns are shown across the 2-meter band for a model designed for 146 MHz. Step 2: Design. A: 275.7mm. B: 746.2mm. C: 103.7mm. D: 29.8mm. E: 142.2mm.
