Can anyone help to identify this antenna?

[Ubbe]

the power company can send out a signal via a local FM broadcast station to shut everyone down.

Seems like a reasonable application, but wouldn't the residents complaint a lot when they come home from work and turn on lights, start cooking dinner, turn on TV, and when they need the air conditioner the most it turns off? And the same in the morning when preparing breakfast, taking a shower and so on and the air conditioner stops working? It must be used just for emergencies to avoid an overload breakdown, or after a power outage to manually start air conditioners in a controlled manner to avoid another overload issue? The broadcast transmitter must have bad coverage if they need that type of antenna?

That looks like an FM broadcast band antenna and there are no short elements, its just the way some of the larger elements mount to the boom leaving some extra length. Its common for some power companies to make a deal with a property owner to shut down air conditioning and related items during peak power usage and they like to use FM broadcast sub carriers for this. They will install and FM antenna and a little box of stuff that connects to the air conditioner or other power hungry items so the power company can send out a signal via a local FM broadcast station to shut everyone down.

Interesting. I've seen some of the antennas that PG&E (California) uses and they've always been UHF. I wasn't aware that they used VHF/FM freqs. Learned something new.

It's a voluntary system, and they pay you to use it. Here's an example.
