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.

RF Choke Detail
Five turns of feedline coax 7-inches in diameter taped to the support mast 1/4 wavelength away from the feedline.  In the background you can see part of a tri-bander element.
