These antennas are pretty far apart, about a quarter mile as far as I can tell.
I will look around the next time I am driving around in my golf cart and see how many I can spot. So far I only know of 2 in my neighborhood but there may be some I have not seen.
The last time I talked to my line man buddy, he did not know much about them. That was right about the time they installed them tho. Maybe he knows more about them. A different crew does this.
