modified 2/16/2:
posted noise measurements in response to slashdot comment.

Test Methodology

The Linksys WAP11 access point was 1120' from the test antennas. I'm tired and I'm going to bed. I'll add more soon.

Performance Measurements

All numbers are in dBm as reported by the Orinoco Client Manager software's Site Monitor. Lower numbers are better. Power doubles for every 3 dBm increase.
