| WB2MIC 6 METER Fast-Build 3
Element Cubical Quad Antenna I had been using a 1/2 wave vertical antenna on 6 meters for a few years and thought it would be nice to have some directivity and gain. One 10-ft length of 1-5/8 inch PVC pipe and 2 lengths of 1/2 inch PVC pipe were staring at me. I figured, surely, I could build a quad with that. So, I did. I used #16 leftover insulated electric dog fence wire as elements. I used scrap cable television coax cable that a friend gave me as feedline. In the first hour of testing on 6 meters I worked (from Vermont): New York, Indiana, Tennessee, Oklahoma, Kentucky, Florida. Total cost of construction = $23.50 as I did not have enough 1/2 inch pipe. |
