Attic antenna installation question
Posted on 9/13/17 at 7:41 pm

I'm looking to install an attic antenna in my house and I can't figure out how I'm going to wire it. The main TV in the house is on a shared wall with the master bedroom.
House is a 1.5 story so that wall goes all the way up, 20 feet or so, but I have access to the top of it in the attic. I can tell there are 2 coax lines running down this shared wall, one for the living room, one for the master bedroom.
I assumed I could just unplug the wire for the living room tv and hook it to the antenna in the attic once installed. Problem is, the coax that is in the living room is being used by my ATT fiber modem. Is there a simple way to get OTA signal to the main TV on that coax, or will I be fishing a wire through 20+ feet of wall?
I thought about accessing the coax from the master and just pulling it through to the living room and using it for the antenna but I'm not sure how much of a pain that will be.
Don't care about getting OTA signal to any other tv but the living room.

Coax splitter in the attic.

I'm reading that the internet signal, and tv signal don't exactly jive?

Drop another coax down the all from the attic.

Probably the best way to do it. You should be able to disconnect the existing coax run to your living room and use it to pull more wire up to the attic with nylon or poly twine connected to the existing coax in order to pull the existing coax back down to the living room.
Shouldn't be hard at all.

This is exactly what I did and it worked like a charm. I just had someone in the living letting me know that I was pulling up the correct cable. Make sure you join/tape the cables about a foot together so there is no chance of it coming apart inside the wall when pulling up.

This should do what you want. Since AT&T uses HPNA, both HPNA and OTA can reside on the same cable, but you have to combine the two first somewhere in the cable system. Most people combine it as it enters the house after exiting the modem but before it goes to any cable boxes, which is how I show it here. You must use HPNA diplexers and splitter. Also, you should use a bandpass filter on the antenna and the cable modem to prevent them from rebroadcasting the OTA back out of the modem and the HPNA signal back out of the antenna, which is against the law.
AT&T probably already has a bandpass filter installed where the cable enters your home. If not, you can request they put one on it by explaining to them that you are adding the OTA to the system. They are required to if you tell them. Or... just do it yourself. It will require you to have a small length of coax to install in-between the original incoming cable and the connection into the modem. Same for the OTA antenna.

This is what I did. Wasn't that bad tbh
