Interestingly, the Moxon beam shows gain over a dipole (=2dbi) and a small F/B even on these higher frequencies. I taped the car side antenna wire to the brace so it wouldn’t fall down. It isn't a true Moxon designed with his formulas - that would have shorter elements, a little less gain, and a lot more F/B. spiderbeam high performance lightweight antennas. Forward gain almost identical to that of a two-element Yagi but with better F/B ratio. It is a directional antenna that provides great performance. Moxon Rectangle Antennas - Lighter and better than Yagi Post by Grzyadms4x4 » Tue May 19, 2009 5:00 am After I made my super duper collapsable folding/flexible yagi, I thought to my self, "self, this is great, but there's a lot of parts. 5:1 or less. Start off from a stop smoothly, slow down and do not keep stamping on the brakes. 2 dBi is achieved at the horizon in the elevation plane and everywhere in the azimuth plane. 0 MHz, although model predicts higher at the upper end of the band. Call (410) 774-5416 for more information. Assembly was easy and I had it together and tuned in 15 minutes. Amplifiers and Modulators. A circular antenna is the best and has in a certain direction 1. Because the electric field in the rz directions would be 7 times the field contributed by one element alone, the antenna gain in these directions would be 72 times greater than the gain for only one element radiating in that direction. The moxon antenna is a relatively simple antenna to build as it consists of just 2 elements, yet has a decent gain of about 6 dBi and a front-to-back approaching 30 dBi or more. If your antennas are pointing vertically the WiFi signal is going to go out more horizontally. The amount of power lost during the transmission is the antenna isolation. The antenna tuner system can match loads of up to 26:1 initial VSWR within a frequency range of 3. There just isn’t much support that way. The Moxon Rectangle on 2 Meters. (With a downed aircraft, one may have to hold the antenna in either manner--or at an intermediate angle--for the strongest forward signal. While the stock has been a strong performer lately, this trend might continue since. Radio Kit Ham Radio Antenna Tv On The Radio Radios Hams Electronics Projects Ham Radio Ham The hexagonal beam (or known by many as the hex beam) has become a wildly popular antenna. I can usually do that with its rubber duck antenna in similarly challenged locations. The Moxon antenna is probably the best “bang for the buck” antenna you can build – and do it for about $100 dollars US. 4dB), while the Moxon is about 3dB down, at 22. Stock #818308. Splitter, Twin Cable, Antenna.
