If you have a piece of 300ohm TV line, I have had reasonable success with this simple low SWR, dual band antenna, specially on the more common low elevation passes:

Oops, this should have gone to the list. My two way wrist watch is acting up. Or build a j-pole for 70cm. All these can be built inexpensively with items from your local home improvement store. You might also contact local hams.
BTW, since it is for RX only, the dimensions aren't very critical.
Ciao baby, catch you on the flip side 73 de W3AB/GEO
You can say "over", you can say "out", you just can't say "over and out".

20 years ago, Jerry Brown, K5OE wrote a series of DIY Antenna Construction articles, some of these were published in the Amsat Journal. These satellite and VHF/UHF antennas were built by countless AMSAT members across the world. http://wb5rmg.somenet.net/k5oe/

Jeff, K7XQ had problems with all Eggbeater designs (not impressed with performance). He developed a Tall Quadfillar Helix Antenna ... but no longer posted on web page.

I have been trying to find a used Eggbeater or similar antenna to use to listen for Satellites. The exchange on the USD to CND currency is a killer. I noticed many plans to build one on the internet. Any suggestions which one would be worth trying for RX to start?
