This is post 2406 in a continuing series of simple ham radio antennas.

If you want to boost the performance of your 2 meter rig, be it a HT or full-featured transceiver, then try this Co-linear design from "Sparky Projects."

Here are the main points:

Whether going for a walk, or backpacking, you may be interested in a portable antenna solution, this is a full size 3/4 wavelength co-linear antenna, with 75 ft (22 m) of cable for 2 metre amateur radio use, but contained in a 18" x 2.5" (460mm x 70mm) tube. The original co-linear was designed to be mounted on a car by Fred Judd (G2BCX), all I did was make it portable, telescopic, and added a ground plane system More details can be found here, along with photos and the original plan http://sparky-projects.co.uk/colinear...
