I use this - wireless HDMI
It worked great, no running of cables when that is hard to do. I had one on the trailer, I can turn the TV on Satellite and pick a channel, turn on the transmitter and go outside and watch the same program outside.
The new trailer has a satellite plug outside so it is now just sitting in my garage collecting dust.
Ouch, $250 MSRP seems a bit rich compared to a cable..
Drilling a hole in the wall and running $20 worth of cable would seem to be much more in line with OPs request..
Alternately as someone else mentioned, HDMI wall jacks can also be put in..
