will 2 interfere?

I have 2 TV's. One in the LR and one in the BR. I finally figured out that when Dish Network takes 7 or 8 channels and runs 24 hours of some or another "marathon" like Ironside, or "Rawhide" they are using space (airtime) that could carry other, newer programs. But the greed is alive and well around there. So I bought an "Apple TV", hooked it up, and played a bit before letting it find its way into the box of TV "stuff" that infrequently gets used. BUT, I have been seeing more and more ads extolling the virtue of this (and similar goodies) that would allow me to "kick my $125 a month Dish habit in the butt!"

Ahhhh.

NOW, the question. I'm running my Mac with a 2wire router (via that steeenkin ATT) that connects my computer, and all of the netflix, amazon prime, hulu+, etc, sends a tidy signal to the living room, and thats where we watch TV. MOST OF THE TIME! But I like to kick it like "The HEF!" Dress down, lay in bed and watch the last hour or two in reclining luxury. So, the dilemna; I assume I will need to buy another Apple TV (or similar). Will running two of these receivers (I guess thats what they are) create overlapping static or power issues? Will static or audio interference occur? I DON'T want to buy a "HAWPAH" (hopper) because Im free and clear of any 2 year contract. So, I hope to hear from you as to the viaility of running two "Apple TV units about 40-50' apart from each other??!

2 thoughts - I might buy another brand, but wave lengths are wave lengths, so that could fail??!!
Other thought, I might try to buy a hopper used, or even from dish as a refurb if it isn;t a killer price. But MOSTLY, I'M hoping that you can tell me that it would work FINE! I am SO DONE WITH DISH, the local cable joint, and I also get about $400 a year in junk from Directv.

HELP! And thanks.
