Can I go coax to cat5 and back to coax?

[cconway25]

Is it possible to go from coax to Ethernet and back to coax? My in-law wants to use his cable box outdoors and he already has cat5 running from indoors to where he wants the hookup. So I would need to convert coax to cat5 inside, and then back to coax outside where it can get plugged into the cable box. Any help is greatly appreciated!!

Short answer: Yes, at a cost + performance degradation.

You need a balun with the right connector type at each end, it can work quite well but will be limited in distance.
You'd need to know the impedance of your coax (possibly 75 ohm but there is a 50 ohm standard as well).

There are probably active devices available that would increase the distance but I haven't checked.
honestly unless it's a difficult run then a new piece of coax is going to be the best option.
