TV cable for antenna run?

Is it possible to use TV coax cabling for an antenna run. How might splitters in my motorhome affect efficiency?

I don't use the cable for the three TVs in my motor home and am considering attaching an antenna to the nicely located outdoor connection in my utility bay.

Inside, I could use one of the TV ports with adapters to SMA to my HT.

Please let me knoe if you need any other information in order to make a recommendation.
