DWL-900AP and Linux

[Jason Hecker]

Diversity antennas on wireless devices tend to use just the one antenna for 
transmission and both for reception.  You may see professionally installed 
2.4GHz stuff with two conifer type antennas spaced vertically a few metres 
apart.  This space diversity helps with fading due to phase cancellation 
effects.

Anyway, if you can't turn off the second receiver antenna, desolder it and 
short it with a 50 ohm resistor.  This will terminate it properly and the 
receiver voter circuit will only end up seeing any signal coming from the 
primary antenna and select it always for reception.

Cheers,
jASON
