Receiving Cable/Satellite Television in Colo?

I am running analysis over many live TV channels (both broadcast and cable networks). Currently I have an office setup with couple of DISH receivers hooked up to HDMI capture cards in a machine that's doing processing in software. To expand to dozens of channels, I'll need to host this somewhere so I would like to set it up in a colo. I'm not sure if this is a common requirement as I can't seem to find many places that advertise TV reception as part of their services. Any pointers would be appreciated.

I was very close to doing a similar thing with $dayjob.

Most colocation centres - good ones, anyway, do rent roof-space, although these are usually used for satellite backhaul. I can't see why they'd mind putting TV satellite receiving dishes on their aerial space, provided that you're paying for it ;)
