Two Meter Portable Quad

What 1 needed was j small, rugged 2 meter antenna I could use for various applications, including portable operation. Initially. 1 wanted to use it as a satellite uplink or downlink antenna without Az-EI control, so 1 also needed a wide beamwidth with reasonable gain. I decided on a 2-element quad, running wire msi dt r PVC water pipe. The result was a sturdy, waterproof antenna, To correctly size the elements, I used a test dipole to determine the velocity factor of 14 wire inside the PVC pipe...

Big antennas and big linears require even bigger money, I don't have big money so I set out to Imd an inexpensive solution. Thi criteria The antenna had to be fixed-directional preferably to the north to take advantage of polar F-layer propagation , it would hopefully have 3 dB points at least 30 degrees .tpan gt et still...
