The Moxon Rectangle was first introduced by Les Moxon, G6XN during the 1950's. Since then it has been a very popular limited space Yagi do to its very compact size.The antenna presented and shown in Fig. 1 is often carried in my car to be QRV with a fishing rod as a support mast. It is a 2-element Moxon yagi for the 2-m-band, which has been supplemented by two further elements to form a dual-band directional antenna for the 70-cm-band.To construct the antenna, first select a suitable length of grey 25mm conduit (as a minimum 1m but if you make it longer, you will have more room below the coil to attach to your antenna support).

Jun 25, 2020 · We just need to apply the scaling factor of 0.945 to the original sizes with a calculator and a little rounding to sensible numbers: So for the reflector we need a wire 2051+384.5+384.5 – 2820mm long and for the driven element 2 wires 1025.5+305.5 = 1330.5mm long. Now we can build the antenna and have a good chance of it working!

The 2-element moxon structure for the 2-m-band was created with the help of the small program "Moxgen" [1] by Dan Maguire, AC6LA, and subsequent processing with EZNEC +6. The interesting properties of the Moxon beam were discussed in detail in [2]. It has a gain of almost 4 dBd and an excellent f/b of 35 dB.Recommended for the MFJ-1890, 10-METER MOXON ANTENNA. This rugged close-spaced 2-element Yagi has a driven element and reflector with the tips folded toward each other to minimize turning radius. MFJ-1890 for ten meters spans a mere 12 on a lightweight 50 boom. Weighs just 8 lbs., yet delivers an amazingly clean cardioid pattern with 3.3 dBi ... This improvement will assist the outcome to be more efficient antenna with less losses regarding gain. According the test i perfom compare to the Folded W8JK: -the gain improvement is about 1dbd. -The performance on 30m band is better. -The performance on 10m band is better. -The antennal still bi-directional without any F/B attenuation. » Greater Gain & F/B. » Switched Beams.

We shall use AWG #12 copper wire and set the design frequency at 7.1 MHz so that the beam will cover the band. Fig. 1 shows the detailed dimensions. Since the Moxon rectangle consists of a driver and a reflector, the main forward lobe is outward from the feedpoint.A moxon is a monoband antenna. Although people have tried to make them multiband, they are not. Get a hexbeam if you want a multiband wirebeam antenna. They work great. Below are two eznec plots for my 17 meter moxon at 30 feet using solid copper wire. So, that's the story of my moxon.A Moxon Rectangle (Yagi) for 14MHz - 20m. The Moxon Rectangle was first introduced by Les Moxon, G6XN during the 1950's. Since then it has been a very popular limited space Yagi do to its very compact size. The Moxon Rectangle comprises of 2 elements, a driven element and a reflector element. The tips of each element are bent towards the other ...(with 10 = top) The Moxon-Beam was introduced by L. Moxon (G6XN) in his book "HF Antennas for all Locations" (RSGB- Publications, Great Britain 1993). This beam is a 2-Element-Yagi with radiator and reflector and reduced size to about 75% of a normal beam. The 2-Element-Yagi with reflector has normally a 0,2- lambda -boom and an impedance of 50 W.10 or 12 AWG solid copper wire works pretty well for 2M and up. You can use a drill to twist the wire and it will straiten it out and work harden it to make it stiffer. Moxons are awesome. My first sat contact was using a Moxon built using corflute (plastic sign board) and self adhesive copper foil tape 1/4” wide.Designing Moxon Rectangles by Equation and by Model L. B. Cebik, W4RNL (SK) There is an urge among antenna builders to discover "magic formulas" for determining the element lengths of various antenna types. In most cases, tradition sets the form of these formulas in the following terms:

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 ...Not all TV programming requires a cable subscription or streaming service.

Frequency in MHz. Wire Diameter in millimeters. Calculate. JL1NIE source code. Moxon algorithm and diagram are from Designing Moxon Rectangles by Equation and by Model. The Moxon tails produce radiation to the sides, since the current in these portions of the antenna is not negligible. The tip-to-tip coupling, when combined with the mutual coupling of the parallel parts of the elements, yields a current magnitude and phase on the rear element that is nearly ideal for maximum front-to-back ratio. A Hybrid Tri-Band Moxon-Yagi. One of the features of the Moxon rectangle that appeals to many builders is the reduction in side-to-side width of the antenna relative to linear elements. On 20 meters, the normal 36' elements are reduced to 25' side-to-side--a value not much greater than the width of a 15-meter beam.The Moxon Calculator simplifies the antenna design process by computing the necessary measurements.
