I have an Antennas Direct DB8 with a Channel Master CM-7777 30 dB, 1 input, 15V
Inside the condo, the signal is split to three receivers through an Extreme Broadband BDS103HB -5.5dB
I believe the preamp has died on me because I can't get any signal as of a few days ago.
I checked the PSU and it is reading 14,6V
I checked the current draw and it is reading around 185 mA.
I am not the one who installed the rig on the roof. A professionnal (???) did it as membrane roof, side flashing and bricks were involved.
The antenna is pointed toward 165° (true azimuth) for maximum signals for the channels at about 75 miles from my location (Burlington's towers). Also, the closest channels are at about 20 miles (Montreal's Mont-Royal's towers) and located at 259° (true azimuth).
I used to get those channels: 2.1, 10.1, 6.1, 12.1, 17.1, 15.1, 3.1 (real 20 WCAX), 62.1, 5.1, 33.1, 44.1
I never got WVNY (22.1) but would be happy to.
Apart from the PSU voltage reading and the current draw reading, should I do anything else to confirm the CM7777 is dead?
If the CM7777 is dead indeed, can anyone point me at a replacement?
