Look at the bottom. The :TBolt: has a stabler on the bottom and while the :hurricane: does not and has two intakes going into the mouth while the :TBolt: only has one.

The Hurricane really has two horns that merge into a single large "mouth". The Thunderbolt has just one horn and throat.
Here is another photo of Luke's siren, easily showing off the double-horn shape. The rotator assembly was removed when this photo was taken so you're only looking at the horn shroud. It isn't symmetrical like a Thunderbolt.

And the "stabler" I believe is called a mounting plate. Attached to the standpipe and the mounting plate is a mounting flange. Not quite sure how the Hurricanes works but it seems it's somewhat similar?

The 'stabilizer' is a twin-arm bracket that holds up the heavy Thunderbolt horn. Meanwhile, the Hurricane uses two small triangular casting supports glued onto the top horn's neck. They are glued in place during the casting process so it all hardens into a single solid assembly - they cannot be removed once casting is finished.

The Point Beach Nuclear Power Plant in NE WI. also had a system of the round horn Hurricane sirens in the late 70's thru the 80's. My family just happened to be driving by one in the summer of 1984 when it was going off for a test. I saw a poor guy walking below the siren covering his ears. We drove past at 55mph... Siren was facing us as we drove past-VERY LOUD!! VERY COOL DOPPLER EFFECT AS WELL. Wish I would have had a means of video taping that day..

Openblast 64 found this information in an old NRC paper from back then. Do you remember what unit it was? We know they had approximately 4 Hurricanes that were later replaced by RM-127's in the mid to late 1990s.dispatcherman wrote: ↑Sat Feb 15, 2020 5:09 amThe Point Beach Nuclear Power Plant in NE WI. also had a system of the round horn Hurricane sirens in the late 70's thru the 80's.

Looking at a map. It was near the intersection of HWY 42 and CTY RD V. (Iirc).. I thought there was one further north near the Kewaunee Plant as well.

There was a Hurricane in NW Milwaukee behind an old night club called ATTIC WEST. This was the mid 1980's. It was northeast of the intersection of HWY100 (180) and Hampton Ave.
