Yes. But even better and neater, check this:

That reminds me... I'm guessing the attenuator is to keep the antenna from pulling in interference right? I for the life of me can't find the attenuators that came with my receivers, I guess RadioShack has them... Are they really necessary for that though? I would think not as long as there's no interference on the TV2.
my 625 came with the little external antenna that screws in to the port for it. Can I put a 5 ft piece of coax on that to so I can hide the receiver in the closet and put the antenna up on a wall..??
i would have guessed the antenna was a substitute for the front sensor..??? are you sure..??
He's right. We overlooked the fact that the TV1 remote is IR-only. You need a UHF Pro remote in order for the radio to work. Unless you plan on using the TV2 remote for TV1.
There is another alternative. A number of years ago I got something similar from Radio Shack. Sender and receiver look like small pyramids. Just put the receiver pyramid in front of the sensor to control TV1 output.
Do a google search for "Radio Shack remote control extender" It's less than $45.
And as others have said, you can put the antenna on coax to move it from behind the Dish receiver. I had to do that for the remote 2 to control the TV2 output reliably.
IR to UHF converter is what that is. I feel it would be cheaper to run the pigtail and buy a new remote.
