DirecTV DVR with King Dome - How to use 2 tuners

[CallThisCamping]

Because we moved and DirecTV set me up with a genie at home, I found myself with an extra DVR. I already have an owned non-DVR receiver in the MH, so I thought I'd put the new/old DVR on the front TV and move the non-DVR to the bedroom TV since there was a satellite outlet there.
Both outlets are home runs to the King Dome on the roof.

So, here are my 2 questions.

1) The DVR has 2 F connectors for the 2 tuners built into the box, but there's only one wire from the King Dome. I know the receiver supplies sense voltage to the antenna. Is there a device that I can use to split the King Dome wire to use both tuners and still supply the 18V to the dome? Then I could watch something and record something else. (or watch a recording and record 2 different programs. I cannot do that now with only 1 tuner connected.

2) What is needed to be able to watch a recorded program on the bedroom TV like we do at home? The only wires between the 2 locations are component cables from the switcher, and the co-ax that runs separately from each receiver to the dome. There is, of course, no internet between the 2. Thought about running a x-over cat-5 between them, but it's a lot of work as the bedroom TV is in a slide, and I don't know if it would work. Do-able, but hard. I have not yet run a loose wire just for testing purposes.

If they ever invent a dome (or any other roof mounted antenna) with dual SWM outputs, you will be able to do what you want with your current wiring.

Here you go. All you have to do is run the one output to the power inserter and go from there. You can have up to eight outputs. If you have a Genie it will use up five, although only one coax. Each DVR uses two, but each only requires only one coax.

You're welcome. I have always found that understanding the process helps immensely in understanding the answer. A simple "You can't do that" (my first sentence above), while correct, is not sufficient.

If they ever invent a dome (or any other roof mounted antenna) with dual SWM outputs, you will be able to do what you want with your current wiring.

A thought:

Could you permanently mount a waterproof box near the King Dome and put a SWM8 and PI in it? You would have to find a way to run 120v power to the PI. You would move the 2 coax cables from the antenna to the SWM8 outputs, and get 2 short coax cables to run from the antenna to the SWM8 inputs. That would do what you want and the only NEW wire would be the 120v line to the PI in the waterproof box.

Thanks, that's a very concise description of what I have to do for the end result I want. I don't know if it's actually possible to re-wire the coach as the 'front' TV is actually mid-coach, and that home run makes a couple of turns and may travel through the wall. Don't know. May be more trouble than it's worth.

As wired currently, you can not do this. That is because the antenna does not get 18v. It gets either 13v or 18v. If you send 18v to the antenna, you get 1/2 of the channels. If you send 13v to the antenna, you get the other 1/2 of the channels. The receiver switches channels by switching voltage when needed. A multiswitch takes 2 lines from the antenna. It sends 13v on one and 18v on the other so it always has all of the channels. Then you can connect any number of receivers to it and get all of the channels.

There is only one way to do what you want, and it requires a rewiring of the MH. You want 3 tuners to run off of 2 coax outputs. You MUST run the 2 coax outputs from the antenna to a multiswitch, then run 1 coax output from the multiswitch to the rear receiver, and 2 coax outputs to the DVR.

OR, run the 2 coax outputs from the antenna to a SWM8, plug a Power Inserter (PI) into the SWM8 to power it. Then run 1 coax output from the SWM8 to each receiver. Not all receivers are compatible with SWM technology, so check that first.

My suggestion is get up on the roof. Remove the home run coax from the rear bedroom. Use a connector to attach it to a short coax cable, labeled "RB". Attach another short coax cable, labeled "ANT" to the open coax output on the antenna. Run both short coax cables through the roof into the front TV area where the other antenna output goes. You are now set up to wire up a multiswitch (or SWM8 and PI) with both antenna coax outputs, and have a coax to the rear bedroom.

Unless your DVR and receiver were designed for "whole home DVR", you can not watch programs in the rear bedroom that are recorded on the front room DVR. And if they are designed for "whole home DVR", you probably have to use the SWM technology to do that.

Sorry, should have been even more clear. The main KD coax is going to the front AV area. The Aux KD coax is already in use going to the bedroom receiver. So both KD outputs are already in use, but not tied like a SWM setup so the bedroom receiver can't see the DVRs recorded shows.

What has to happen is for the main output to be split to hit both tuners. I don't think a common splitter will do the job. And, being essentially transformers, they don't pass DC.

When we had the KD. There are 2 connection from it.
One is MAIN the Second is AUX.
Run a cable from the main to #1 conn. On DVR
Run second cable from AUX to #2 on DVR.

You will need to drill a second hole in roof .
