SOURCE: IS MY TV DIGITAL?

Unless you are connected to a cable TV or satilite provoider you will need a digital converter box connected between your tv and indoor antenna to recieve the new digital over the air signal

I want to use two (2) 311 dish receivers with only 1 outside antenna.

I called RCA's 800 number on the back of the owner manual--got a response that said to replace the unit since only the up-down channel changer buttons were not working. Using another remote (universal) now--cost only $5.

SOURCE: I have a Westinghouse 26 inch TV.

I carried my Westinghouse TV to the basement. Unplugged the antenna from the digital converter box and connected it to my digital TV. I then re-scanned for channels and found channel 9. After carrying the Westinghouse TV back upstairs, I connected the original set-up and tuned to channel 9 which was now showing on the screen as no signal. From that point I moved my VHF dipoles until I had located the correct position for reception. A little labor intensive, but I was fortunate to have another antenna that was receiving channel 9.

Your problem is definitely the input signal source to your tv. It is extremely rare where a new tv has a tuner signal sensitivity problem. The best thing to do is to replace your current set of rabbit ears with a different set of powered rabbit ears that have a higher gain rating with a variable gain control. Please note that the gain control setting is critical when setting up your tuner for auto-programming. If the gain control is set too low or too high it will result in your symptom.

If you still can't get it to work you could try buying a line amplifier which you would install to the rabbit ears before the tv. If you still can't get it to work you'll have no choice but to purchase an outside antennae as a result of your being in a weak signal area as signal quality changes by such things as the switch over to digital upcoming and environmental changes.
