I think the low pitched siren might be a Whelen or T-128, and the high pitched siren might be an STH-10 or Model 5.

That might be a very cool looking telecommunications or radio tower. A far cry from the typical ones with the exposed equipment boxes.

Too bad they weren't painted green or brown to blend in with the trees.

That's because the SD-10, Allertor, and Penetrators used 9/12 rotors.

Basically, it's a smaller version of the T-128, with a smaller sized motor/chopper, and as the name suggests, produces 125dB at 100 feet.

Too bad that couldn't be done with the other companies at their manufacturing headquarters.

Glad that they went with better quality Modulators, and not the dreaded low quality ATI sirens.

Very nice video, it sounds more like a Federal EOWS612 rather than a Whelen WS3016 siren.

I would agree with you with Sentry Siren for mechanical sirens, and as with electronic, that would go to Whelen.
