There are two permits for this site. First one says, remove and replace antennas. The second one is installing new RRH's and hybrid cables.
The first does not have a vendor but second is Infinigy. I looked them up. They are a telecommunications company out of NY.
I think I found permits.
The City of Albuquerque website is hard to search but best to do by address of tower. This is a tower close to me. I know Tmo already put up 600 and 700 prior. This is what I just found. I included picture of google maps.
Edit: the vendor noted is not one Sprint has used in the past. The tower only has Tmo (top) and Sprint (second).
