We have a analog TV with converter box and a TV with a digital tuner. I don't know the make of out antenna, but it is bar-shaped, mounted about 20 ft. We have an amplifier from Radio Shack connected to it and use coax cable. Before the conversion we could get NBC consistently and ABC was sporadic and that was all. After the conversion we could only pick up the CBS station; ABC and NBC would come in occasionally usually in the mornings. We rescanned repeatedly and did the double rescan to clear the memory with no improvement. We have turned the antenna many times and is aimed at the best signal we could get. At the suggestion of someone at the local station we disconnected the antenna from the analog TV so all the signal would go to 1 TV. We now get CBS, NBC and ABC most of the time. We still can't get the FOX stations or PBS. Do you have any suggestions for upgrading the antenna or would the Channel Master 7777 amplifier be a better bet for us. We just want to get our local channels again and the kids want their TV back. I will try to get the link from TV Fool. Thanks in advance for any help.TV Fool
