Hello, here is my TV Fool report:
http://www.tvfool.com/?option=com_wr...d2435f83a94440
I have a UHF directional antenna + pre-amp mounted outdoors using chimney straps. The antenna is 25-30 feet above ground level. The antenna is turned to about 32 degrees magnetic north (used a $5 walmart mapping compass), and is the following model (Antennas Direct 42XG):

I also have the antenna hooked up to a channel master CM7777 pre-amp:
http://www.amazon.com/Channel-Master.../dp/B000GGKOG8 The pre-amp is a carry-over from my last house so I figured I'd hook it up.
The new coax from the pre-amp runs through one old 1-to-1 port grounding block that was already attached to the house. From there the signal runs through old existing coax to the living room to the CM7777 power injector, then a short coax patch cord to the TV.
I'm having two issues with this setup:
A) I would expect to get the numerous channels shown around the main angle of 32 degrees magnetic north, however I'm only receiving virtual channels 25.X (25.1, 25.2, 25.3) and 48.X (48.1, 48.2, 48.3). The other broadcast towers are in very close proximity, but I'm not picking them up for some reason.
B) For every channel received, there are four duplicates of that channel. All of the duplicates have the same virtual channel number, the show is the same and the reception is solid for each. They seem to be identical.
When I unplugged the CM7777 AC power adapter from the outlet (signal still running through CM7777 power injector splitter) and re-scanned, I received only channel 3 (with good signal on 3). I did not receive any of the 25.Xs or 48.Xs. Channel 3 came in on the Samsung TV scanner as "Air" rather than "DTV Air" as channels usually do. Could this channel be the VHF High WDVZ-CA coming from the opposite direction at 214 degrees magnetic? The channel is TV Land, and that's the only info provided.
With the CM7777 power adapter unplugged and the power injector out of the loop (CM7777 mast output running through the grounding block to the TV), I receive only the 25.X channels, with good signal and no duplicates.
Do you have any suggestions on things to try or change? I'm puzzled at the moment. Thanks
