Installed the satellite on the ladder to keep from having to store it. If that proves to be an issue, I can remove it. Yes, I'm so anal that I bought the black dome to replace the white one that came on it. Trailer is wired to leave the wiring going up the ladder in place, and I have additional wiring if I need to remove the satellite and put it on the tripod.
Theres 2 coax and the power cord going up the ladder in 1/2" electrical conduit. As stated, the wiring up the ladder stays attached, and if I need to, I remove just the dome and run separate wiring to the 2 splitters on the frame, and backfeed into the camper (I'm using the splitters backwards). That's the 50A power cord in the background that makes it look like a mess of cords. I'll probably hit the white coax with some black paint to make it disappear.
The power for the satellite is fished into the outside kitchen where the light switch is, and I still have to decide where I'll mount the on/off switch for the power up the ladder. Inside, I take both coax to a multiswitch which is tucked away in the wall behind the antenna amplifier (nothing to see there, so no pic). The TV1 output on the amplifier goes to the multiswitch so that I can still have antenna/cable, and the 4 TVs go on the outputs of the multiswitch. At each TV I use a diplexer to split the signals to the satellite box, and a single coax goes to the TV. Now I just have to activate the 4 boxes to make sure it all works as designed, which is supposed to allow all 4 TVs to operate simultaneously, on whatever channel you choose (from the same satellite)
