Phased Vertical Array on 20M. Post #1257


If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=G5awjoMRzrQ.

A phased vertical array on 20 meters can give you a boost in gain and directivity on this popular amateur radio band. Bob (VK5FO) gives you a "walk through" of this antenna and a description of the end-fire phased array consisting of 2X 1/4 wave elevated ground plane antennas. This antenna would make an excellent field day or contest antenna.  Most of the materials can be bought at the nearest home improvement outlet or neighborhood hardware store.
