...Nothing here either.
Thought I had one of everything in my sample collection, but not that one. Never have heard of the brand or seen this design.
Any history to share? Where did it come from? LO frequency?

Curiosity keeps me up at night. Possibly an electronics trading, distributor, wholesaler type of thingy. See links below:

I picked it up with my pile o dishes for 50 bucks deal. I can barely make out any spec info from the label.
?
I'm hoping to do some dish setup over the weekend. If I get another LNB with a similar throat mounted and aimed on a dish, I may swap it to see what happens.
?Probably can't hurt anything to unscrew the cover either.

Ok,
For those who like a mystery, more pictures below.
This is the best I can do with my eyeballs trying to read the info from the back of the coverplate.

The last two photos were the only identifying info I could see inside. I think I'd have to get out the electron microscope to read anything off any of the other chips. Did not see anything legible on the circuit board.
I'll try it out this weekend and see if it works. If not, I'll dismantle it further.

The IC is from JRC - Japan Radio Company.
Maker of many fine LNBs and LNBFs. Most know their name from the pop can LNBs on Primestar dishes.

Not Cheap ICs. Looks like a quality build.

Well, after doing some aiming experiments yesterday checking out dish locations I can report this unit still works.
I put this LNB on an old StarChoice 33x30 dish as a direct replacement after I had already scanned a sat and tuned a channel with the original CalAmp 150284.
I then used this LNB while doing some other aiming experiments and tuned Daystar on 123W.

The small chip with the three pins in one of your pictures, the 7805A, is a 5 volt regulator, the other one, BA10339, is a quad comparator, it samples inputs and turns on an output when there is a difference/match between inputs. That LNB looks old and built like a tank! Military maybe? Is there a number stamped into the metal behind the label, visible from the backside/inside of the cover?

Nothing stamped on the inside of the cover plate.
As the unit seems to work OK, I'm going to see what results I can get using it on the StarChoice dish with a motor.
