Years of home brewing has taught me how to do and not to do a lot of things properly. Here are some tips I learned that may be of help with the most important part of an amateur radio satellite station, the antenna systems. Materials to build satellite antennas can sometimes be found among junk most people would throw away. Four wire clothes hangers became the radials. I used this simple matching network:. Solder the vertical element to the center conductor and attach the radials with nuts and bolts to the four corners, then solder each corner.

Last summer I was recovering from surgery on the brevis tendon in my ankle so I was housebound for around eight weeks. As luck would have it the World Cup was on so I was enjoying my recovery with a beer in hand, football and the wonderful weather. But of course, as a radio amateur, I wanted to operate outside in the sun. Being unable to travel I decided to work the FM satellites with my dual-band handhelds. I managed, by swinging around my handheld, to make a couple of contacts via AO so the bug had bitten and plans were formed to construct a better antenna. Time for Research.
The OSCAR station described here is about as far from state-of-the-art as it is possible to get, and still have it work. Virtually everything about it can be improved upon, with better antennas, lower noise figures, etc. I even wrote many of those station-improvement articles myself.
