Icefoglights: here is the satellite dish.

It's a DBS dish looking at a single satellite.  Probably an older Dish Network or DirecTV dish.  It's actually a digital system until the reciever box, which converts it to analog (either A/V or Ch 3) for the TV.

Thanks, icefoglights.
Could I use it for a tv with a built in analog to digital converter or should I just take it to habitat?

It can be used for TV.  Modern systems really aren't that different, just adding the ability to look at more 2 or 3 satellites at a time, and some refinements to make cabling easier.  However, to get TV on it, you'd need a compatible receiver box and to get most channels, an active subscription, as these systems work similar to cable TV.

People also use these dishes for wireless internet antennas.  I read an article about some people that uses two small dishes to create a microwave relay, sending a wifi signal over 100 miles to the receiver.

I think I heard about that too! Except it was using the ionosphere or something.  It was 24/7 reliable too apparently!  I read it in a forum board about radio "DX" and reception though.  Have you ever heard of FM E-skip, Icefoglights? Or do you do nighttime skywave AM DXing? I do the latter all the time where I live, some nights it's great! (I often pick up San Francisco, Portland, Seattle, etc).

I've never tried DXing.

Well, the old generator went bye bye while I was out of town.  It had a good long service life, but with two better generators available, and the work it needed, it wasn't worth holding onto.  It needed to have the valves and seats reground, and the carburetor had too much slop in it's parts to properly regulate the engine, and would have to be completely rebuilt or replaced.

Family member threw it away or something?

I knew someone who moved out here (no city power) with a 4Kw Briggs & Stratton from a garage sale.  Man that thing was loud, rough-running, etc.  (The lights would start flickering and it was time to go adjust the choke).  It also backfired EVERY TIME it was shut down.  (The old-school short-the-spark plug style shutdown). 

It finally blew a head gasket and they got a Honda EU2000i...
