Going from Coax to HDMI is fairly easy, all you need is an ATSC tunner/decoder These receive digital TV and output it in several formats, one being HDMI (in some cases).
Going from HDMI to coax is technically easy though a bit costly.....
There are HDMI modulators, these are basically pico-TV stations, the take HDIM (most will also take A/V and a possibly other formats) in and output ATSC television, Just like your local TV station. Only have enough power though to feed a few TV's via COAX.. In the old days they had Modulators for A/V,, Those cost about 20 bucks and if you have an older Motor home with a DVD player and a box of many buttons.. the box has one built in in all likelyhood.
On your Sat Receiver (Which has been digital since day one) the coax out, if present, will be NTSC however (not HD)
