They should tell that to whoever installed Perry, GA's Whelen Vortexes. They're only about 40' up at best

I'm sure everyone remembers the topic:

REAAALLLY low Whelen Vortex sounding wail

That Whelen is nowhere CLOSE to regulation placement. But who is to tell them what to do anyway?

The inside area of the pole top mounting bracket will accept a pole that is no greater than
10.00? in diameter. On large scale projects, it is beneficial to order the pole to be ?gained? to
a top diameter of 9.5? +/- .50? for the top 30? section of the utility pole.

I think this may clear some questions up a bit.

I don't think you can beat this... It is in Seaford, DE, on N. Pine St, near E. King St. It is on the very top of the tower. Calvin says it is an STH-10, but it looks more like an Eclipse 8 to me.

The highest mounted siren that I know of in Huntsville is the 2001-SRN at Jones Valley Elementary School.

By the way Allenorgan42099, you need a / in the closing tag for your Google Maps link.

Definitely an Eclipse 8. You can easily tell from the flared projectors.

Hmm. Looks like I didn't take a very close look at it when I added it...

Oh, well. I need to update the Delaware map anyway.

Just a follow up to the post I saw earlier about Jackson County's sirens not being mounted to regulations, here's one at their fire department in downtown Jefferson.

Now spin the camera around directly behind you and you will look uphill. Some of those houses are ear level with it. I know this is technically the wrong thread but just wanted to kinda piggbyack off the revive in this thread to show that most all of their sirens are mounted that way. Now, out in the countryside and at Arcade City Hall, they are mounted on telephone poles maybe 30 feet off the ground.

There's a Thunderbolt on the 26 story Richard B. Russell Federal Building in Atlanta, GA.

The WPS 2810 here in downtown Columbus is up pretty high up on a metal pole. I believe that this and another siren in the city were mounted on the same poles of the Thunderbolts they replaced. This actually is the first siren I recorded and put on YouTube.

Off topic but that building in the background looks like a smaller version of our Clark Tower in Memphis:
