Inbound Transmissions

Inbound Transmissions

The center of the satellite dish. I assume the rounded piece collected information reflected off the sides of the dish and reflected them down into the center pedestal-type structure, where a pyramid shaped hole was left in the middle.

I was surprised at the absence of a light on top, the sky was full of low flying aircraft.

Yeah, you've got it right on how it worked. In the hole would have been a data collector that would have translated the analog signal into digital and passed it on to a computer. I can think of two reasons it didn't have a light: the light might have interfered with transmission, and if this was a secret at the time it was put up they wouldn't want anything to identify it. After it closed down they probably just forgot to put a light on it...

That's a sub-reflector, in the center of the antennas primary reflector there is a large "post" (called a feed horn) that houses the LNA's (Low Noise Amplifiers). You have it right in your description I just wanted to add the industry terms of the parts. Great photos and thanks for sharing them. I should have visited this place before I left Maryland...

Yep, thats' the thing.
Thats' what does it. AS friends told me years ago , the dish is 'only' a reflector or "catcher' that reflects the signals back up to the feed horn
