I have one wall(exterior) aerial, can i connect 3 other tvs wire free from that?
Without any pics or additional info, I can only guess “Yes”. It sounds like you could try using an amplified 1-to-4 splitter. This kind of splitter needs to be plugged into a power outlet in order to boost the signal from the aerial. You will still need 4 more cables, however. You connect the aerial to the splitter and then connect the 4 TVs to the splitter. If you don’t get an amplified splitter and just use a regular one, the signal from the aerial may be too weak. I hope that is correct and helpful. Good luck with your project.
