Handy-Yagi for ISS & other satellite contacts
Interested in getting into satellite communications "on the cheap", I recently built a version of the "dual band handy Yagi (directional antenna)" by Tom Hart (AD1B) and purchased a Yaesu FT60 to fit onto it. I just finished the project last week. Today I squeezed a bicycle handle grip onto the end of the yagi, programmed the ISS downlink frequency and looked up the next ISS pass. I didn't expect to hear anything -- but when I stuck the Yagi toward the western sky at about 1525UTC [Sept. 1, 2008], I heard (what I think was) a school contact -- the op explaining some of the challenges of the space program for about 1 minute -- and then I lost him (it's broad daylight so I was guessing at his location). The antenna is simple to build. It has only directors (3 for 2M band, 7 for the 70cm band) made from steel rods on a wooden pole that is about 1.5m long. The handheld transceiver/rubber duck antenna is mounted on the pole as the driven element. For those interested in building this handheld satellite antenna, see the May 2008 issue of QST Magazine, p. 42-43.
