Not to bump a closing thread, but...
New digital TV channels in many areas use higher frequencies. The displayed
channel is often not the real radio frequency channel. For this reason, you
need better performing coax than RG-59. The old cable It is smaller, but
more lossy at higher frequencies, and easier to be damaged or kinked.
Use RG-6 with a good shield - and keep in mind that real quad shield cable
will need coax ends (fittings) that are harder to find. Home run these
cables, it is the only good plan. A 12 volt powered four way
amplified splitter will cover the basics. New high end homes use these
types of systems for entertainment distribution.
'Compression' style ends are best. They need the right kind of tool to
install, but they don't pull off. There are youtube vids of how the
coax compression fittings are installed. You will find that it goes quicker
if you use a 'twirly' stripper / prep tool.
If you are installing satellite, consider your system layout to keep your
receiver and wiring distribution as simple as possible.
While WiFi is (just about) on every entertainment device and WiDi is
emerging, if you want to future proof, run CAT5 or CAT6 4-pair wherever you
think you want to put an entertainment or automation device.
Even if you don't use this cable for data (in the classic sense), you can
transport HDMI signals over CAT rated cable with low cost adapters.
You may not have a need today, but it keeps your options open.
Everyone has a different approach to powering electronics, but there are
12vdc TVs, 12 volt Ethernet switches and so on. This simplifies wiring,
eliminates the shock hazard, and you can manage the power consumption. The
whole RV industry supply chain is built around this approach. You just have
to seek these types of devices out as you make your plans.
Digital TV broadcast signal standards in use today didn't include a
protocol for mobile viewing. But small amplified antennas give good results
when stationary.
I hope this helps as you make your upgrade plans.
