Tip of the Day… TV and Antennas. Start with the antenna. Note the type and any controls. Some RV will have a crank up antenna and some will have Omni-directional antennas. If it is a crank type, crank it up. Does it operate smoothly? Once extended, turn the antenna left and right. Go outside and verify that is turns.
Once the antenna has been checked out, now it is time for the TV(s). If the RV has multiple TV there will probably be a controller somewhere that controls what inputs go to what TV. In our MH it is above the drivers seat. If you can’t find it, ask the seller. Make sure that the antenna is connected to the TV(s). Turn on each TV and set it up to find the local channels. This will take a few minutes. Once the programming is done, the TV should automatically go to one of the local channels.
There may be a booster somewhere in the RV. Ask the seller for its location. When the RV is set up for Cable/Satellite the booster is off. When using the TV Antenna you will need for the booster to be on (usually a red light will be on). Verify its operation.
