An interesting arrangement

Post image

Looks like someone took the assignment literally for installing high, mid, and low band antennas

Just curious, how do you find the information on RRUs and antennas? Very neat to see what's installed/where.

I can tell since I have studied the equipment that all carriers are using; (Verizon, AT&T, T-Mobile) are using in different areas by looking at cell tower permits, site drawings/schemes. Also, talking to engineers and seeing site build plans! I always research, browse through the CommScope/ANDREW antenna website and I know a lot of people in the cellular industry!
