Trouble with high vhf signals

[96ozarker]

I have an RV antenna with a wingman feeding to a Sensor pro booster and then to two digital TV sets. I have experienced on multiple occasions recieving a strong signal on the Sensor pro (58-60) for the channel, ie 10, but neither tv will tune in the signal. (I have had similar problems with channel 11 at a different location.) One situation the signal level did not change but I could get reception during the day but not at night. This seems to occur on high vhf channels, at least I have not experienced it elsewhere. Any ideas where my problem might be?
