Antenna for UHF VHF Links →
1 Element 50 Ohm Yagi
The dipole is mounted vertically 250mm in front of a metal support, the gain is 2,65dBd at 5,5dB F/B
A centre-fed coaxial dipole for 4m
The feed is essentially a delta-match, which makes use of the intrinsic capacitance of the two co-axial stubs
Antena Jpole - TOPFKREIS 435mhz
This antenna is nothing more than the coaxial version of the Jpole antenna. It consists of a half-wave radiant element, the electrical equivalent of the half-wave dipole
Antena yagi 2 metros
An antenna for vhf 2 meters, and a simple three-element yagi with range adjustment worked well for me
2 Meter Halo Antenna by Mike Fedler
Wanted an antenna that was simple, horizontally polarized and omni directional

50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
