In a difficult area (attic), the ancient antenna and cables provided a solution, increasing the signal from 10% to 90% and capturing all channels. Installation indoors (requires a socket) is very easy with screw plugs, with extension to two televisions, one in the living room and one in the bedroom, both with excellent signal. It is best to place it as close to the antenna as possible, then add as many meters of cable as needed without any loss.
