My problem is i have a rather large house with stupidly stick walls, indoor antennas do not work what so ever unless i hold it flat the window, i do not want to feed cables around the house, and all the tv entry points are only down one side of the house. Ive tried searching for wireless Coaxial Sender/recievers to no avail. so a different approach is needed, i was thinking is there something i can plug into the entry point the rebroadcast the signal so like a reverse antenna, so i can then use indoor antennas.
Any help would be great, thanks.
