HB9CV Antenne
I was able to set a maximum standing wave ratio of 1: 1.1 at 144.300 MHz. The HB9CV works really well.
Helix antenna for 2 metre satellite
Construction of the helix antenna is mechanically a little more difficult than a Yagi and requires a reflector behind it to function properly
J Antenne For 2m
A J antenna in fact a ZEPP antenna can be considered as a whole wave radiator with one dipole half (=1/2) folded
