I currently have DirecTV and Internet on the same coax cable in my house and no OTA, very similar to this diagram:



I'd like to remove DirecTV and add an antenna (and keep Internet) with as little work as possible, and I assume I just can't plug the antenna into the 8-way SWM where the dish plugs in now. Do I just need to add a pair of diplexers after the SWM and before the DECA to add the OTA signal like this:



Any expertise would be appreciated. Thanks!

how many tvs? you may need an amplifier if you are splitting the connection more than twice I think..

Just two TVs, but some distance. About 75 feet for one and 35 feet for the other.

So put something like this (https://www.amazon.com/Channel-Master-Distribution-Amplifier-antenna/dp/B001RCBX56) before the diplexers?

Is my original thinking about doing this with diplexers correct?

Looking at this guy's DirecTV replacement video as well:

Thanks.

Id get two and put them just after... you should only need one splitter in that case
