A:Answer Yes, I have used a splitter that way. Shielded outdoor coax RG6 wire. If you go more than 25 ft may need a signal transformer depending on your antenna location and your OTA region strenghts. I chose to set an outdoor antenna to avoid interferences you might get in an attic,again it all depends your home location and elevation within the OTA reachs, signals dont go through hills or high elevations, dont forget earth is not flat.
