For anyone who installed a satellite box in your RV feeding multiple TV's and not having a RF remote system take a look at this. This works with your current IR system converting to RF. Direct TV SD boxes are only IR controlled.

I got one hoping for the best and am happy with the results. It controls my Direct TV box and Samsung TV's. No need to run to the satellite box to turn on or change channels any longer. In service for about 2 months used about every other weekend and still on the 1st battery charge. Your results may vary, but I am a happy camper with it.
