Antenna for UHF VHF Links →
3 x 3/4 l 2 meter Vertical antenna
The antenna has 3 radiating elements. The phasor coil L1 and L2 functioned as phase shifters in order to maintain equal phase in all 3 radiating elements
5-Element-Yagi for das 2m-Band
Self-construction of a powerful 5-element Yagi for the 2m band with a novel adaptation technique
70cm mixed mode helix
The radiation pattern is optimised to peak toward the horizon, with a gradual reduction in gain towards the overhead sky
