Another Noel here. If the ones you have in there now are working, the new ones will. It is just a simple swap. If Just take out the old ones and throw them away. find flatscreens at Walmart that will fit. Install them the easiest way possible. Keep it simple, they are so much lighter that lots of options can be opened. OTA antennas take whatever the station broadcasts and you can receive. Satellite hookups depend on what the satellite sends and what your dish will receive. I am not qualified in that area. The newer OTA antennas are much better that the older ones, if your is old, just replace the head with a new one. HD broadcasts will work fine on a SD only receiver, just don;t look near as good. Older Analog receivers will NOT pick up Digital OTA transmissions without a convertor.
