The macth range has a total length of 70 cm, from the connection point on the coaxial plug, to the end of the range rod

2 element bands 10 meter 30 meter

Version of the EH antenna using the L+L type matching network. Included in the assembly is a tuned trap

Diy antenna for limited space 10m and 20m band square halo

Antenna can be taken apart and is therefore well suited for the weekend in the garden or for the field day

Very short boom (3,00m), for 28,0-28,8MHz lightweight construction possible

By adjusting the length of the gamma match and the series capacitor, the vswr can be adjusted to 1.1:1 at 28.4 mhz

Design frequency: 28.300 mhz usable bandwidth 600 khz, gain 7.5 dbi, front/back ratio 20 db

Una grande copertura di banda con basso ROS

5 elements "vee" log-yagi for 10m band- boom lenght 4mt, Gain over 10 dBd

The hb9cv-beam is a 2-element-yagi with two driven elements and was introduced by rudolf baumgartner

This is a high-gain, wideband owa optimised wideband array yagi which covers the whole of the 10m band with an swr of less than1.1:1 from 28-29mhz

Gamma match will be made with a 1/2 aluminum tube and a 75 cm coaxial piece of RG8 without sock and sheath inside the tube

Antenna multibanda realizzata con due canne da pesca in fenolico lunghe 7 metri

It is a half wave dipole designed for the center frequency of 28.400mhz but should cover most of this 200khz spread with low SWR

The middle parts consist of 2 m long 20x1,5 mm aluminium

The formula adapted to ours: L = 150 / F, that is, if we put the frequency F in MHz, we get the average wavelength L in meters, at least in theory

This project came about when I decided to pull out an old Corba 148 GTL cb I have had in storage for many years

The Homebase-10 is a simple to make wire halo antenna for 10m 28MHz built using parts available from the local DIY store

The ring antenna, where to place it? Above all, there is no choice: only the windshield and the windshield have a perimeter of about 3 m

The critical part on this type of antenna is always the variable tuning capacitor which is located at the hot spot of the antenna

Building a vertically polarized Moxon could be a practical solution to use portable

Element is 8 ft and 4 inches long each there's 2 for a total of 16 feet 8 inches, the reflector is 17 ft and 7.3 inches long with the spacing at 6 ft and 7 inches from the driven element

The Lazy H is bidirectional but offers a pleasant 6 dB gain. This could be a good project

The Homebase10 is a simple to make wire halo antenna for 10m 28MHz built using parts available from the local DIY store

The length of the vertical wire to 17 ft 4 in and I had a SWR of 1.1 to 1 at 28.200 MHz.I had good SWR of 1.4 from 28.000 to 29.000 MHz

Ideal for the 28 MHz QRP 10 watts maximum, perfect for portable traffic thanks to its ease of installation

Do you need a small, rotateable DX dipole for 10 Meters that can be made from an old TV antenna in a few hours

Do you need a small, rotateable DX dipole for 10 Meters that can be made from an old TV antenna in a few hours

The antenna the ZL Special seemed to indicate gains as high as 7 dBd and front-to-back ratios as high as 40 dB.2 moreover, the antenna was relatively simple to construct
