I asked someone that lives near it and he says it has some neighbours spooked because sometimes it makes loud, low humming sound. I said they must be talking about something else because if its a cell tower it wouldn't make that kind of noise.
Then again, if the gizmo were to make some kind of noise, that giant cone thing its sitting on might amplify the sound somehow.. |
Hey, Mark - Suggest to those neighbors that, next time they hear the noise, they might want to pay attention to the wind, direction and strength. There is a lot of thin metal, with lightening arresters on each of the units, too. Not hard to understand how an audible harmonic might be generated in wind strong enough, just like a whistle. And then there are those ventilation louvres, too, allowing air communiction with a presumably open church interior below. Lots of opportunity for accoustics. The beige, square units look like they could be microwave relay antennas, but it's hard to know the shape of the antennae under the covers. The frequency often can be inferred from the shape and dimensions of an antenna. It's also possible that they are just control electonics or even power back-up batteries. KD9ADA, out.
