Don't count on that being a factor -- a 2.4GHz antenna is VERY 
unlikely to be big enough to couple RFI from your ham station to any 
place it can get detected unless you're on 2.4 GHz, and then it 
would likely only hit the wireless card. Far more likely is a pin 1 
problem or a shielding problem.
