[amsat-bb] J-Pole Antenna

Looking for a simple omnidirectional antenna for AO-7 (B), FO-29 and VO-52, I came across a description of a J-Pole - dual band, single mast antenna, done by Dick Jansson, WD4FAB several years ago.

This looks like the solution for my situation. Before I start building, I would like to know, if somebody here has experience with this antenna.

Thanks and 73
