What kind of antenna is this?

And why would it be tied into my two Dish Network antennas?

This rig is on the roof of my office building. We're trying to solve some cell phone reception issues. The contractor couldn't figure it out and left it in "as is" condition. I'm trying to figure out what everything is.

Thanks in advance.
Sorry about the Flickr issue... I've now changed it to allow access. Thanks for letting me know.

Would love to help but we can't see your flickr photos; they are marked as private.

I doubt there would be interference to your cell phone equipment from a Dish anyways, but best to see what you are talking about first before I am certain about that.
