I have a few questions which I hope some of you can answer.
In the way of background, I have a Samsung HLN437W tv and a Samsung SIR-T150 tuner. I just recently installed a Channel Master 4228 antenna in our attic to try to get HD channels over the air.
1. Usually I can get FOX (49), ABC (52), CBS (53), NBC (55), and WB (57), but I never seem to get UPN (27). I live near Crabtree Mall in Raleigh, and I thought that all of these towers were basically the same direction from our house, so why can't I get UPN (WRDC-DT, 27)? Is it really broadcasting? Is the signal a lot weaker than the others?
2. I tried adding an amplifier, but I still could not get UPN. It did allow me to get PBS (59), though, which I did not expect. I tried both a Channel Master 3042 TV Distribution Amplifier and a similar product from Radio Shack. If I'm understanding this correctly, both were supposed to boost the signal by 13 or 14 dB. According to the signal strength indicator on my tuner, neither amplifier had much effect on any of the signal strengths, except for PBS. The strongest signal was never more than 10 bars, which looks to be about 50% of the range shown on the meter. The strongest signal might be 8 or 9 bars without the amplifier. Are there stronger amplifiers that I can use? If so, which one(s) should I try?
Thanks in advance for any help you can give me.
