I was fortunate to visit one of these properties in MO last week. I got to climb up top to fix some WISP equipment. Awesome experience. Call me a geek, but I have always been a coldwar comms buff.
A retired AT&T Long lines site! these sites were used accross the nation to relay various forms of communication. They were quickly phased out due to limited bandwidth, as fibre optic and higher frequency larger bandwidth hops formed. some AT&T sites used the NEC500 Microwave transmitter/reciever setups as well as other multichannel transmiter/reciever repeaters. a mere 3 to 5 watts was all it took to transmit from one hop to another, but with a 35DB gain horn, there were no problems.
Theres a HUGE Microwave Tower Way out in the middle of nowhere up here in Michigan, it has HUGE dishes on it, I have the FCC Anntena ID i cant find out what the tower is who owns it or anything hese the FCC antena ID: 1001265
the nuke proof ones are filled with concrete and weigh a ton i have removed them , watch me vid and see a 400' w/2 removed and a 1500lb. dishand mount. have fun out there .
Oh yeah, 240 feet is perfect. I love the TD-2 horns still on the tower. They used to have them here too but took them down once Ma Bell got off microwave and went into fiber.
the horns replaced delay lenses, even uglier things. Western Electric horns were new in the mid 60's out dated by mid 90's retired in place RIP...They still can be used believe it or not for wifi back bone microwave radios. But no one does. TOO much gain. ( for the FCC)
they weigh 2500# and the hardend ones weight is 4000# each. Hardend is the term for nuke proof! Yes the towers and antennas were nuke bomb proof at some sites... I have worked on them many times.
VERY KEWL VIDEO

People who call these nuke proof are not joking. AT&Ts historic involvement in the Cold War is amazing. Google it sometime.
Many of these sites were staffed in the 70s and had blast proof bunkers under them.
