Performance? i haven't got a brilliant way of measuring the antenna, i do know that when the moxon is pointed stateside, the european signals fade

A 2M vertical polarized antenna I built, the front to back ratio is very good and conforms to the model

The built antenna had an SWR of 1.6 :1 at the design frequency

I went for the vertical Moxon supported at the top-center with rope

The moxon rectangle is a small compact 2 element yagi antenna with folded back elements, shows a 17 mtr version made from fishing pole whips

This 2 meter antenna has 2 characteristics that make it a very favorable antenna to have,the boom length is a very short 40 inches, the 4nec2 forward gain is reported to be 15 dbi

Shown below are plans for 2 over 2 element wire moxons for 40 and 15 meters, gain shown incorporates eznec ground gain, +5.5db over freespace

Moxon hybrid at 25 ft. with low noise characteristics

A moxon rectangle higher f/b wider bandwidth scale to other bands, interleave promising transverse tip elements have 4 functions moxon coupling physically balanced efficient capacitive loading low wind load on main elements

Built around a 1/2' pvc frame, 6 meter moxon antenna is made from #8 aluminum ground wire available from radio shack

A standard Moxon for 40 meters is about 46 feet wide and 18 feet long. An 18 ft. boom is doable and about the same as the quad that will share the boom

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

A vertical moxon rectangle, the rear garden runs roughly nw to se, so a reversible moxon gives useful coverage

Using one of the on-line Moxon calculators, the dimensions were calculated, the difficult part was trying to remember all about sines and cosines

I ordered two types of 5 meter long fishing rods from eBay for building

The input impedance of our antenna is 50 ohms, balun 1: 1. with coaxial RG213 of 15 cm in diameter and 5-6 turns from the winding

I used two bamboo rods joined together with vinyl tape, the total length of the two rods is 3.35m 11ft. for the boom, i used a 2.1 metre length of fibreglass pole that

Another advantage of this antenna is that it may be fed directly with co-axial cable

Choice was to try a moxon wire antenna made by very thin wire to reduce weight

The full band goes from 28 to 29.7 MHz, the usual working frequency in SSB is around 28,500

A standard Moxon rectangle designed for 17 meters would be about 19 3/4 feet wide

Compact two element beam antenna with about 5.5-6 dbi of gain and a 25db front to back ratio

Compact two element beam antenna with about 5.5-6 dbi of gain and a 25db front to back ratio

The voltages across the capacitors on 17m are high, at 100w, we're looking at 350v across the 18pf reflector load capacitor and 475v across the 44pf l-network capacitor, at full legal power on 17m, these voltages are about 1400v and 1800v respectively

Connettori in pvc, questa configurazione senza viti consente di impostare l'antenna in meno di 2 minuti

Made for 10-15-17 and 20m constructed from 6m crappie fishing whips with aluminium bonded to the ends for mounting, these are secured to the base with homebrew 6mm u bolts. the elements are connected to a homebrew 1:1 choke installed in the feeder box

The antenna seems to have a very good front to back ratio, we are using a 88 foot center fed zep as a comparison and after raising the antenna the Moxen beats the zep every time and also hears signals the zep does not

Scribble by hand a first draft of what this new antenna could be

The impedance is 50 ohm bandwidth is quite good, swr is under 2 from 28.0 MHz to 29.2 MHz

But the antenna must lay above a 30 meters 100ft tower, last experience teach me that the resonance decrease about 50 khz when put antenna a top of tower

Moxon vhf 144.300 MHz

I use crappie fishing poles, which are 16 foot telescoping fiberglass rods in an X configuration

For pmr channels, the results of the calculations are invariant at the mm scale for the 8 channels, in fact, they are identical from 445,927 to 446,115, ie from -0.08 to +0.02 around these

Moxon Antenna Calculator public domain program

Here we see the software set to design an antenna for 17 meters using 18.1375 as the center frequency, by changing the frequency and wire size, the software calculates the measurements labeled a-e, what could be more simple

The entire antenna therefore forms a rectangle but occupying a space much smaller than a corresponding unbent 2el beam such as the HB9CV<

6.5 mm diameter for the elements, 15 x 15 mm boom 40 cm long,direct supply with rg 58 c / u or kx 15 on bnc, gain before 6.3 dbi,gain forward / reverse 15 db

A compact switchable antenna for 40-meter ham radio

One fully portable 6m Moxon beam that breaks down into a bag easy carried off and easy to assemble in about ten minutes

The flag is built with fiberglass fishing pole supports and a bolted aluminum plate and angle hub,very much like my Moxon

This is an intriguing antenna. Compared to a full-size 2 element yagi it is much smaller, yet gives comparable performance
