Anyone who wants my ten-paragraph answer can ask for it, but this is already long enough. Please realize that if you don't address this, but instead ask why I don't do something else, you'll be asking for the kind of long response that has brought objections in the past.

I have a client who needs to get a DirecTV 4K signal from a DVR to a TV in the adjacent room. Wire runs are impossible. Brent has me hooked up with the right model number for an RF solution but wired is always better.

There's also a fresh set of home runs to the garage, CAT6 to every location and RG6 to these two locations. Runs are probably 60 feet long... do you know of baluns or other devices that would get the signal to the TV with a layout like this:
Balun at DVR
Cable to garage
Splice of cables -- plugs and socket, punchdown... must be defined
Cable from garage to TV
Balun at TV

The thing that has me worried is the splice in the middle.

Thanks.
