Another inexpensive, but effective alternative is a simple telescopic whip antenna which you can get at any local Radio Shack.
The antenna has a BNC connector on it, which should fit your radio.

Then just take the center of the frequency range you expect to be using. (eg: 118 to 122 MHz... so maybe 120 MHz) then divide 234/f where f= is your frequency. This will give you a quarter wave dipole length in feet.
Adjust your telescoping antenna to the correct length using a ruler then take a Sharpie marker and mark a ring on the antenna where to extend it to. Viola, you can collapse it whenever you need to, then just extend it out to the mark you made when you want to use it. In the example above thats 1.95 feet or 23.4 inches. It's a bit unruly to wield around the cockpit, but on the ground it isn't too bad and the improvement is significant over any rubber-duck antenna.
