I think I might have found some telescopic antennas that will work with some handheld radios:
Looks like they should fit the 2-watt Realistic models, maybe with a little modification of the bottom of it, if it has a flat tab instead of a screw that goes in the bottom. Sure, they're not the nice center-loaded antennas, but hell, if it works "good enuf", it's better than a broken antenna.
