The Moxon Antenna is a simple two element parasitic array antenna that is popular with Amateur Radio enthusiasts for its simplicity of construction

Half wave end fed antenna for 11 meters, can be hung vertically or horizontal. horizontal is good

After installing it and if you find that the swr is a little high, you can lower it and cut a wire from the ends of the dipole

Tubes for aluminum antennas from 3 cm to 2.1 cm in diameter, the longest element is the reflector, about 5.6 m, the boom is 5.3 m long

The antenna 11 meters CB is the flat antenna ground 1/4 wave this antenna is omnidirectiona

The dipole antennas built with coaxial cables with short-circuited ends are also called bazooka

Loop magnetica produce poca o nulla tvi e la ricezione è chiara e libera da scariche di origine artificiale

The Antenna is an antenna model for 27.305 mhz. band of 11 meters, gamma match It will be manufactured with a 1/2 "aluminum tube and a piece of coaxial RG8 of 79 cm will be inserted inside

Recommend building a 4 element quad, four elements gives the highest gain to size ratio of any type of beam in existence

Centralized Frequency 27,305 MHz

Dipolo centrandolo sul canale 20 CB corrispondente a 27.205 MHz

La base è stata ricavata da una5/8 dei 27 MHz

Realizzare un'antenna per la banda dei 10 mt. da utilizzare per qualche uscita in montagna

Delta-loop-is-a-triangular-antenna-with-1-lambda,-then-the-size-is-300:-27,205-=-11.03-meters,-so-for-each-side-it-is-11.03-m:-3-=-3.68-meters

In this setup you have a horizontal polarisation, the total length of the wire is 11,07 meters

If you want to communicate with mobile units, with vertically polarized antennas then you must use vertival polariztion

Full wavelength: 300 / 27.555 = 10.887 x 0.94 = 10.234 m top sections of antenna: 0.64 wavelength: 10.234 x 0.64 = 6.550 m for each leg

The antenna they named it hentenna, in japanese hen means strange, another strange characteristic of the hentanna is that if it is mounted horizontally

For 27.500 Mhz lambda=10.9091 m 1/2 lambda/100=5.5 cm

It is clear that a hidden car antenna has a lot of advantages it cannot be stolen or broken, it does not deteriorate

The capacitor i built supports easily 5 watts but i think i could use it up to 300-500 watts, nevertheless i never tried power greater than 12 watts

Delta loop antennas the formula delta Loop 1 element

EFHW antenna in the photos for 11 meters, with a 64:1 unun

Apparently the configuration of the elements folding and interacting combine to present the coax feedpoint with a 50 Ohm

Calculate Dimensions,wire diameter,in millimetres,frequency of operation,in MHz

New oko loop the 10-11m band with 80 cm through or as quadratloop 4x4 8,82 cm and 5 eckloop 5x0,5m respectively pmax 100 w

This antenna as in each frame has 2 elements in the vertical position and 2 in the horizontal position, there will be an optimized reception in these two polarizations

The boom is 5.7m long 4 bamboo elements

The bazooka dipoles can be mounted in a variety of positions, horizontal, vertical, slope, or in a inverted v fashion

Costruire la crocera centrale utilizzando uno dei 2 giunti a T da 20 mm. ed i 2 pezzi di palo da 30 cm

Is to get an small antenna, this is a great solution. the hb9cv antenna is smaler than a 3el. conventional yagi but you get the same gain and caracteristics.

3 elements wire Yagi for 11 meter we call it the Skypper due to the manufacturer Alex 1SD019

Here is my first reliable and still working yagi antenna for my radios pmr446, 14 elements, 2.5 metres long, gain 13.6 db

The gain is excellent, on average 8.30 dbd 10.45 db iso. the forward/rear a/r ratio exceeds 22.5 db across the entire band. the r.o.s. it is less than 1.04 :1 between 27.4 and 27.8 MHz
