TV channel problem

[John&Andrea]

It may be the antenna, most stations are HD signal these days. You may not be receiving on the RV if you do not have an HD antenna. My 2 cents, no a specialist.

We have an outdoor antenna on the house. We can get NBC, CBS, and ABC. Oddly enough if it's raining we can only get ABC.

I'm gonna guess the signal is a little too weak for the RV. Assuming you have used the Wingard search function and knowing when the weather is bad you loose channels in the house that would be my guess.

Not sure it will help with this problem but maybe in the future.
Download from Apple Store 2 different TV station locaters. One is TV Towers USA and the other is Winegard - TV Signal. Gives you someplace where to start.
