New DIY Siren Units, Testing a second siren

[djscrizzle]

I built a *second* siren unit, and have photos of them. I'll test them tomorrow afternoon, and have video up in the A/V section.
The newer of the two sirens is located in the loafing shed, where there is a bomb/tornado shelter. The older of the two is located at the main barn, about 750 feet away.

i know this a probly a dumb idea but. to make it rotate ever if you wanted they have those Antenna rotators at radio shack. some how if you go that to work that would be pretty sweet. though they move realy slow

I know this a probably a dumb idea but. to make it rotate ever if you wanted they have those Antenna rotators at radio shack. some how if you go that to work that would be pretty sweet. though they move really slow

I plan on having heads with 4 speakers (omnidirectionals) as the main production model. I'm mostly testing range of one driver as I have 2 sirens and 2 piezo horns installed.
The newer siren has a 10 watt amp, the other has a 125 watts RMS amp on it.

Stay tuned for tomorrow's test videos. One does alert and fast wail. The newer one does alert and Special Function*




* You'll have to see the video to hear the Special Function on siren #2. Hint: its not Hi-Lo, Air Horn, or Attack. Think of a fire alarm.

Random guess: Code 3 tone?

Would these antenna rotators work OK for a siren? Or is there some other kind of rotation mechanism out there that one can purchase?
