Yes, it is a wireless internet receiver - they recently installed a tower to pick up the satellite signal. I checked with the provider and they broadcast at 3.56 GHz. I don't know which preamp I have - I sent the radar map to Antennas Direct and they advised me of which one to get - I think it would be the Channel Master that picks up in the blue/purple zone. An electrician did the install and he followed the materials provided with the hardware.

I have no PBS signal (no audio or visual). Before this event, I was able to receive four PBS stations that were labelled 10.1, 10.2, 10.3 and 10.4 - they all had different content and are broadcast from the tower in Presque Isle, Maine. The WAGM signal is picked up as 8.1 and 8.2. This signal has virtually the same power as the PBS signal and the tower is also located in Presque Isle, Maine. I can still receive both WAGM signals with a clear image. I also get CTV out of Fredericton, NB and Global TV out of Moncton, NB but the picture is not good.

I have rotated the antenna full 360 degrees with no gain in signal. I have not rescanned for a signal.

When this started, the TV was on low power and turned itself on with a totally pixilated screen and no audio. Then it turned on with audio and no picture - I mean it turned on by itself and I had to unplug the TV to get it to turnoff (could not find the remote at the time). I am wondering if there was a signal or power surge (all were connected to a power bar). The inside power unit for the external receiver and a router were located next to the TV.

Any advice would be appreciated.
