Coaxial Collinear Antenna for 70 CM Band - This coaxial collinear antenna was built to test for my own consumption whether or not this antenna method actually works. the guiding principle is that we have multiple 1/4 wave elements fed in series , the radiation from each adds in phase to produce a large vertically polarised omni-directional antenna with substantial gain
