I have been having trouble with poor tv reception on our Model 24bhs camper.The manual talks about cranking it up and turning it.This model is a stationary one that doesn't seem to work very well.I would just like to be able to pick up the local stations at where I am camping.I do run the tv through the auto program mode to try to pick up channels.Is an antenna booster what I need ,and if so what kind would you recommend?Thanks,Dan
