Can I send HD over Coax from a DirecTV receiver to a second TV

My house is wired with Coax cable that I can manage in the basement to connect certain lines. I have a receiver in my basement that I would like to also send feed to a second tv in HD if possible. Currently I have an old composite to Coax that I use to send feed but obviously it’s SD. Is there a good converter for this purpose? Also, if there is something to convert to Ethernet and back that would also work but not as well. I have googled this and get a mixed bag of results every time.
