Antenne HB9CV 2m 144 MHz
A gain of about 15 dB and lateral dips from -30 to -40 dB from the front.In VHF, the size of a 3-wave half-wave antenna is 1 meter wide by 60 centimeters long against 30 centimeters long for HB9CV

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
