I live west of Chicago about twenty miles. I have absolute no problem picking up my HD pictures on any of my channels except one. Which is CBS Chicago broadcast on channel 3 and it is the only channel that is not UHF. My picture keeps breaking up and pixellizing. I have a brand new Radio Shack antenna combination UHF/VHF and only about 40 feet of lead-in RG6 coax and the antenna is about 25 feet off the ground with no obstructions. I can almost see downtown Chicago on a clear night. I have a Mitsubishi HD 500 receiver. And like I said earlier the only problem I have is the signal from CBS on channel 3. Any suggestions as to what I can do to solve this problem. It is driving me crazy. There is plenty of good shows on CBS that I would like to watch but the picture break up is very frustrating. I am willing to spend a few extra bucks on a good VHF antenna, does anybody have any suggestions that might solve my problem.
