Mini horizontal V 2 element 20 meter
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

Antenna 20mt 14 Mhz Links →
Dipole 14mhz/50mhz
The dipoles are not in contact, are tightly coupled and spaced approximately 7cm apart. This technique is quite applicable for a larger number of dipoles
Delta Loop UN7CI 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
Dismantable for 10m-20m
For the bands 10 m and 12 m the Yagi is working as a reflector-radiator-Yagi, for 15 m and 17 m as a beam with radiator and director
End Fed Halfwave Antenna And Matching Unit for 20-30-40 meters
an EFHWA for 20-40 meters, and the other is a matching unit for the antenna
Fuchs-Antenna for 20m
Vertically mounted on a fibre glass telescopic tower this aerial makes my main antenna for 20m qrp work
