Our 3731 FL has 3 TVs , I removed the wall plates only 1 coax cable run to each. Put splitters in a drawer!
Put a male/male connector in place of spliter. All 3 now work on cable and antenna.
For Dish in living room ran a coax from Dish box to where coach cable was and using same m/m connection switch. Only tv with Dish box receives signal but that works.
Only pay for Dish if OTA or park cable not available.
Oh and do tighten all connections.
