I was a Canadian defense contractor from 1986-1994. This Canadian station was part of the DSCS (Defense Satellite Communications System) which was a US Department of Defense and NATO global network. The station provided secure voice and data communications between major military terminals.

When the guy says that "anybody can do it," he's not kidding. "Amateur," unlike in other fields, in astronomy is not frowned upon, as amateur astronomers do a LOT of observational work and tracking of small bodies with their smaller telescopes that the larger observatories just don't have the allocation time for, not to mention making a lot of discoveries of their own.

Actually, it's microwave absorber foam There used to be considerably more in there, but we ripped it out. Originally, there was 15kW of X-band radio waves travelling up waveguides through there, and waveguides are NOT 100% leak-proof, so you don't want them coupling back into the receiver side--so, absorber foam.

I'm not sure that converting from a Casegrain to a prime focus is a good idea. The whole idea with the Casegrain is that it's easier to design the subreflector to properly illuminate the dish than it is to design a feedhorn to properly illuminate the dish. By going to a feedhorn rather than the subreflector, they've probably decreased the efficiency of the dish by a lot, essentially making it electrically much smaller than it actually is. Seems like a rather large technical blunder, and 5 steps backwards on a project that's already extremely challenging and doesn't need any "un-forced errors" as it is!
@patchvonbraun
Жыл бұрын
Actually, in order to illuminate that sub-reflector at lower frequencies, you need a MUCH MUCH larger feed-horn to give you the proper gain to illuminate the sub-reflector. We did actually think about this. The prime-focus feed is working just fine. The F/D of the dish is about 0.32, which means a modest-gain feed, which is what we have. Not our first rodeo....
