|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
Director (Left: D1) = 233.2 in.
Driven (DE) = 240.5 in.
Reflector (Right: R) = 247 in.
Per Side Dimensions
Director (Left: D1) = 58.35 in.
Driven (DE) = 60.15 in.
Reflector (Right: R) = 61.7 in.
D1 - DE = 47 in.
DE - R = 36 in.
Feed Point Detail
Center insulator is porcelain.
Direct solder connect coax to loop.
Wrapped with black electrical tape.
||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.
Nothing special. A block of pine (temporary) with 8 holes. Fours
sets of U-bolts, back brackets and nuts. Rotator is the the
