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

3 x 9 Element F9FT vertikal gestockt
The electrical design is a classic crossed-dipole with 75-ohm phasing section, the difference between the 36-ohm characteristic impedance of the antenna and the 50-ohm feedline. This results in an SWR of about 1.3 to 1

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
