This can be useful when you want to take a snapshot of the window and you used one amongst several antennas (Dual-dipole, Yagi, Moxon, Tee-pee,) and you want to identify it. Mark Smith 1,196 views. After the most recent fox hunt I thought that a smaller antenna would be helpful, so I went for the moxon for 2 meter, material used: 32 mm PVC tube etc, coax cable, glue, tie wraps, 4 mm brass bar, propane burner (you can't bend brass when it is cold). The PVC items are readily available from the local hardware store and are very inexpensive. Each way that I thought of, ended up requiring some type of guying system. Originally designed by Les Moxon G6XN, the antenna is stealthy and is an ideal solution for those whose space is limited or restricted, but also gives the user a directional antenna for a smaller footprint. I must compare the IOio antenna with the Arrow antenna because it is our reference antenna. It was not a surprise to see that at 45° elevation this antenna has a 5. Notice that the radiation resistance (impedance) is about 90 ohms. 00! In Stock. Post #1026. Check the calculator and his site out. 2 MHz , using 25 meters of RG-213 cable.

Mount anywhere using lightweight TV antenna hardware. MOXON Background Several designs emerged in the 1970s for reduced size beam antennas implemented by folding the elements. Right: 3D far field pattern, with 2D elevation "slice" highlighted. However, if you want a good receive antenna in a very small space, multi-turn loops are a good solution. """NORTH 7""" lsb 38, AM 19. A full wave loop, compressed in dimensions has much less than 1 dBd gain. Since the diversity of VK2ABQ dimensions in the literature suggests a sensitivity to the conductivity of the antenna structure, the portable Moxon beam requires a minimum of metal to test the model dimensions. I don’t want to get an antenna tuner yet. Many Hi-Fi tuners and other radios have input sockets that will accept the input from a coaxial feeder, and where no external antenna is used, a dipole antenna can provide an excellent solution. As the name suggests, the length of the antenna is about half of the wavelength of the frequency the antenna is cut for. This is a compromise, but maybe not so serious because both objects are much smaller (horizontally) than a half-wavelength on the lower band. The Moxon and a dipole have about the same forward azimuth beamwidth. Since it is a full wave antenna, you get twice the wire of a dipole into and onto the air. Most of us humans think an element that long is difficult to build an rotate much less keep up in the air reliably even for a single winter. Cebik, W4RNL. Named after the late Les Moxon, the Moxon rectangle is a extreme range UHF control antenna that fits right onto your radio's Long Range Control System. Collectively we have all drawn on the experience of Les Moxon, G6XN, and his work to transform the VK2ABQ 2 element. MFJ-1890 for ten meters spans a mere 12' on a lightweight 50" boom. ArrowAntennas. To communicate over the horizon to an amphibious ship or mobile on the move, or to a station 60-190 miles away, the operators should use NVIS propagation.
