Anybody here from southeast Michigan? On Van Dyke near 15 mile Rd.,
there is an Ameritech Building on the east side of Van Dyke. It has a
HUGE rotatable beam, probably log-periodic and all-band. I am guessing
the main boom is over 60 feet long. Has anybody else seen it? I wonder
what they would be using a HF antenna for? It looks a lot like the
antenna near Bethany OH, if that is any help. I am also guessing this
antenna is out of use nowadays. I used to monitor High Seas phone
traffic, but never realized there may be a receiving station in our
vicinity. Also used to hear Great Lakes phone services on HF and got one
of their very last verifications around 7 years ago, them telling me
they were being supplanted by cell and satellite services. Possibly this
was part of a similar network.

The FAA is fond of antennas like that. A backup communications
network for air traffic control, I think. There is/was one at
the FAA radar in Discovery Park (formerly Fort Lawton) in Seattle.
