Hello, I have a 622 installed with one tv and also output to a 2nd TV. I have attached photos of my install. The first is coming from the Dish on the Right. The green wire is just of course the ground:

Now this is the 2nd and this is what goes into my crawlspace. Can I still combine my OTA signal on this line?
Thanks in advance.

Also I have a 2nd COAX cable to hook up a 3rd tv and would like it work just like tv #2, how do I do that?
