Delta Loop for 7, 10, 14 and 21- MHz


The antenna was designed to work from a field conditions at amateur’s bands 7, 10, 14 and 21-MHz. The antenna has SWR less the 2.0:1.0 at height of the lower side 1.2 meters above the ground

Linear loaded short dipole
As the propagation conditions getting worse for 15 m and 17 m, I extended my linear loaded dipole on both sides by 1.8 m in order to cover the 20 m band. SWR is ok without modification of the 1 : 4 transformation line

Mini horizontal V 2 element 20MT
An electrical 1/2 wave length of RG58 as a 1:1 transformer. Using the antenna analyzer from the ground the following measurements were noted, impedance 25 ohms SWR 2:1, the antenna was resonated to 14250 Khz

The Shorty Dipole for 14mHz
The dipole is half the size of the usual full sized versions and is therefore about the size of a ten metre dipole

Shorten 20m band rotary dipole
