I agree, the Slim Jim is a great antenna for the meager cost involved in building it. There are a couple of suggestions on the ldsradio.ca Antennas section. One is basically made of aluminum tubing from old TV antenna parts and the other is a roll up antenna that's a great performer made from Radio Shack 300 ohm twin lead. If you make antennas be sure to test their VSWR before putting a lot of power intoi them. Bad a bad match can ruin the finals in your transceiver.
