Hello Everybody!

The siren weighs 2,700lbs. The metal pole needs to be able to withstand
that much weight. The siren will rotate causing a vibration motion. The
minimum height the pole needs to be is 6 feet per government
regulations, however the taller the pole is the farther the sound
carries, thus allowing it to do a better job!


Steel reinforced concrete block.. Can be "assembled" on site.. Just need to
get a crane to the site to lift the siren up there..

Btw.. 2700 lbs sounds like a HUGE siren..
