Don't know, just found out how to do a simple scan, don't really
use wireless myself. The scanning exercise is to investigate problems
that a customer have.

Wouldn't that be problematic. When you put out energy to the antenna,
do the receiver sense that, and if so wouldn't the output energy
more or less mask the input signal ?
