A coaxial collinear antenna for 70 CM
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 bstantial gain
802.11 2.4Ghz Low-Power Vertical Antenna
Collinear antenna, that was based off of UHF repeater Antennas. This one is more suited for 802.11 operation
