I installed this amplifier in my attic, directly connected to the antenna, to address the signal loss caused by the long cable run to my living room. Initially, my bedroom TV, being closer to the antenna, received a decent number of channels, while the living room TV only managed to pick up 3 channels due to the extended cable length. Since incorporating this amplifier, the results have been outstanding. Now, my living room enjoys a remarkable 30+ channels, even with the gain adjustment set only halfway. I couldn't be happier with this purchase!
