I'm a 90% MT shop. Upgrading everything to 802.11n slowly, just replaced a Crossroads in a 19dBi Rootenna with a QRT-2HnD, 17dBi dual polarity.
Receive signal went from -83 to -70 on a 5MHz channel. I'm quite impressed. I'm going to test the unit and see if it is possible the old one was damaged, but we've never had good signal at this location. I figured I'd eventually lose them as a customer.
