It's called triband antennas. Many older installations, such as your region, utilized 10 port models which support 800/1.9/2.5 to replace older NV dual band hex ports.
Newer deployments typically utilize the 16 port triband antennas or an addition of a dual band 800/2.5 10 port antenna. The new poles they're adding indicate they're site prepping for likely a new antenna add of some sort.
So this is totally .. future proofing the site .. for future capcity upgrades? I figured from the only full build site so far it took quiet some time for it to be turned on these mini macros turn on quick
