Bob,
Since Minneapolis is finally warming up enough for weeds to grow,
I liken threads like these towers to weeds in the lawn.
A good way to prevent lawn weeds is to have grass so thick that the
seeds won't grow.
Translate lawn to this list and grass to on-topic messages.
Wish I had one to

Hi
At least back when dirt was new and I got my first phone license the accuracy
required for AM broadcast was very loose. What drove them to OCXO's was the
need to use X cut crystals rather than AT's. The age of digital dividers had
not yet dawned, so if you wanted 500 Kcps you used a crystal

Jason,
It looks like a directional array for an AM broadcast station. Directional
arrays of this sort are used to protect other AM broadcast
station's primary service areas (i.e., reduce interference to).
The number of towers is determined by the directions that require the reduced
signal

There is a similar array of 8 towers on the southern shore of Lake
Ontario, at 43° 12' 50 N 79° 36' 30 W. I used to drive past it
frequently when I lived in that area. I once found an article
describing the design of that particular array. It is apparently the
antenna for a powerful AM
1. Towers are painted so they may be over 200' tall.
2. Two different tower height variations, 2 each shorter and 9 each taller..
3. Interesting symmetry between the shorter and taller towers.
3. In a congested residential area. Probably too noisy for a Rx site.
4. Gated entry on asphalt
The antenna arrays at these locations in Maine are much more
interesting, especially if you know what they are.

Arthur,
It looks like an Over-the-horizon type site to me as first choice.
It is possible that it could be a satellite observation and tracking site. They
used antenna arrays laid out in a similar fashion.

Apparently, about 2/3 of the transmit power is fed to just one of the
eight towers, and most of the remainder goes to a couple more. So the
majority of the towers are there for nothing more than creating and
aiming the null in the pattern.

These are indeed OTH antenna arrays. The fact that they are near
Moscow, Maine is pure coincidence. These are not de-commissioned,
they are on cold standby.

That might be why the pattern's so small in any direction but
southeast at night.
So what is generally south east from Houston. Galveston, I know,
