Could be one of two things. 1st, if you using the cable connection the power antenna switch needs to be off in order to get cable. 2nd, If you are trying to get a satelite signal to work thru the cable connection, there may be a splitter behind the antenna booster that is messing up the signal. On mine, I took the booster off and connected an a/b switch in order have the satelite signal go directly to the satelite box. If this is your issue, PM me and I will send you a picture and instructions on how I did mine. Also if you are trying to hook up to a lead that says satelite in, that lead is usually not hooked up. You would normally need to have a satelite place on the roof of your unit. Hope that is of help. Others may know of other options or had other experiences.
Finally completed all State visits in August 2011 with a trip to North Dakota.
