But building (partly) yourself is actually quite easy, costs half of a new Cobwebb and is also fun to do. Reviewed by Bob Allison, WB1GCMAssistant Laboratory [email protected] What makes the Moxon Rectangle really different from a standard short-spaced yagi is that the ends of both elements are folded. I pulled the antenna down, lengthened all the wires by 2 inches, and raised it back up. Increasing the size of the conductor will increase the usable frequency range of the antenna (the bandwidth), so at frequencies of about 10 megahertz or higher, consider using copper or aluminum tubing instead of wire. the beam is… well like night and day. A full-size Delta Loop, fed in the bottom corner, is a good low angle radiator and is great for working DX. By changing the frequency and wire size, the software calculates the measurements. My eyesight is nearly gone but was able to get the antenna assembled and in the air. 27MHz Moxon rectangle.

The model results for 17m and 15m were the most promising. It is shaped as a Moxon antenna and works fine on both bands. Some minor adjustments in the feedline length stumbled across it while modeling the antenna and subsequently only saw it mentioned in Les Moxon's book. The Moxon Rectangle was first introduced by Les Moxon, G6XN during the 1950's. Moxon Style Rectangle (Yagi) for 18MHz - 17m. The Yagi portion was a standard driver-director design with about 0. The Antenna Store & More. A moxon antenna project made with wires and fiberglass poles (by AE6AC) 40 Meter Moxon. We build all the components, tune the wires, and pack it up so all you have to do is spend an evening assembling a plug and play beam and have the best broadband hex in the world ready to go. Thoughts have turned (no pun intended) to directional antenna's, having looked at the Yagi and Quad antenna designs, I then stumbled across the Moxon Rectangle, this 2 element antenna offers similar gain figures to a 3 element Yagi, with better F/B ratio's.

Attic antennas •Many types of antenna can be mounted in the attic IF you don’t have Radiant Barrier (Tech Shield). Update: 2011 – This Antenna has never be installed as I bought the UB50 multiband antenna which makes a nonsense to use it anymore. My moxon is 5 stories high. 3 Figure 1 shows the basic antenna layout and Table 1 shows the modeled data for both free-space and 30 foot el-evations. From "HF Antennas For All Locations," L. With the tips of the driven element and reflector bent to nearly touch, it squeezes the width of the antenna into a much smaller space. That seems to be what happened here so when I build a 17M moxon soon that's what I will do.

Increasing the size of the conductor will increase the usable frequency range of the antenna (the bandwidth), so at frequencies of about 10 megahertz or higher, consider using copper or aluminum tubing instead of wire. UHF MANUAL VHF MANUAL HF MANUAL HF AUTOMATIC MISC. DOUBLE BAZOOKA single band antennas. I have discovered that my Moxon was resonant below the 17 meter band. 068 MHz to 18. Smaller than comparable antennas, the LBM models are 70% the width of a full sized multi-band beam or dipole and has a short turning radius, yet handles a maximum allowable power. We use some simple software designed by Dan Maguire, AC6LA, which was first published on L. The vertical used the SOTA beams 30 ft travel mast lashed to a chain link fence post. The SE-20M can be also be setup for 17 Meter operation by resetting the reflector and element spacer settings with an VSWR of 1. The Light Beam Multi-band Antenna has been developed for Hams who want one antenna which enables them to operate on multiple amateur bands. This means, if you build it right, you will be close enough to work both 15m and 17m bands with the same antenna, provided you have a tuner. The next antenna built was a so called Fan Dipole antenna. Cebik, W4RNL “A VHF/UHF Discone Antenna” by Bob Patterson, K5DZE “An Optimum Design for 432 MHz Yagis — Parts 1 and 2” by Steve Powlishen, K1FO. The main category is Moxon antenna plans that is about Links to moxon antenna resources. This design uses a Reflector-Driven element on 17m and a Driven element-Director on 12m. My friend a few hundred miles South of me is working several signals, and they are barely perceptible to me. Linear Loaded Short Ham Antennas. This means, if you build it right, you will be close enough to work both 15m and 17m bands with the same antenna, provided you have a tuner. 20m/2m/440 20m, 2m and 440 MHz Antenna.

It allows the average amateur to compete with the big boys for DX and without spending your retirement to do so. 10 meter antenna temporarily set for initial tuning and adjustment above the rear deck. The other is my NEW 3 Element Beam in this project. To install the loop ouside, I had to weather protect it: The placement was not ideal (small patio next to the 2 story house), but it was immediately obvious how much the things improved: the min SWR went from 2 to 1. 12 m 2 el Moxon-Yagi. Read MORE. Built by ZS1JHG. If you view the various antennas in the What's New section on the homepage, you'll see what we mean. Through this software, you can easily find out four important parameters to build this antenna namely, Radiator length, Driven Stud length, Gap space, and Feedpoint. 146 - Double-D Beam 4dB-Gain. he G7FEK design will allow operation on 80m / 40m / 30m / 17m. 5-dBi forward gain, high front-to-back ratio.

Elements made from 35 to 12mm tube. A270 6S Beam 2m and 440 MHz. No traps or special resonance devices are needed. The Moxon Rectangle was first introduced by Les Moxon, G6XN during the 1950's. I plugged in the moxon and could receive the same signals around an S7, turning the antenna made a noticeable difference, as did turning it horizontal, it was fun making the signal come and go at will, having only ever used dipoles and verticals. 5" in 1" steps; the Gain, F/B and SWR were noted at each step. Reviewed by Bob Allison, WB1GCMAssistant Laboratory [email protected] • Forward gain in free space 30/17m (dBi): 4. Adjust for 1:1 SWR. These wires will form the pigtails (marked X and Y in Fig 1. The baseplate hub assembly uses proven components. The Yagi portion was a standard driver-director design with about 0. The resonant frequency was still way up above the CW segment and the SWR in the CW segment was unusable. My main HF antenna is a popular commercial trapped model and it doesn't cover 160m, 60m or the higher WARC bands (17m, 12m). 5 foot boom, while the higher gain 3 element Yagi’s boom is over 6 feet long. The FM dipole antenna can be a cheap and effective solution, and they can be made in a variety of forms - only two ideas are given above, but it is possible to make a VHF FM dipole antenna in many more ways according to what may be available and what the. I plugged in the moxon and could receive the same signals around an S7, turning the antenna made a noticeable difference, as did turning it horizontal, it was fun making the signal come and go at will, having only ever used dipoles and verticals.

This is the second article describing the two antennas that were used by the Carleton University Amateur Radio Club (CUARC) at Field Day 2010. The Moxon Rectangle was first introduced by Les Moxon, G6XN during the 1950's. The antenna worked well as listen-only on 40m and 17m (but the SWR was out of sight on my analyzer, as expected). In the foreground the ready 70cm/2m-antenna, behind it a 6-ele for 6m. J-Pole antenna is pretty easy to build and usually designed by amateur radio operators. CQ tested the Challenger and on 40m compared to a mono band vertical, they found Challenger an S unit stronger. The 6 meter Moxon is built from 5/ 8 inch OD and 1/ 2 inch OD aluminum tubing with 3/ 8 inch OD solid aluminum for the corners.
