I live in Florida and haven't seen anybody selling Satellite dish's outside of DirecTV or the Dish Network.
There's a link somewhere at the top of this forum for an installer locator. You can look for companies in your area and ask them about the various services.
I remember how many stations you could recieve from them. Including seeing the local TV stations putting together their new segments that would appear later. Was interesting to see as I can remember.
Ahhh, the old C-Band dish. I believe NPS is one of the providers of service for that type of system. You can ask them if they have any dealers in your area.
I have so many questions about what is (C-Band , Ku-band, ect.) what.
C-band, KU-band, etc are just references to what frequency the signals are downlinked at. The lower the frequency, the larger the dish.
I have my home set up for Home Theater, so will a Dish be in the HD format?
There are several HD satellite options available to you. DirecTV has the most right now, but DISH has more transponders and will eventually be able to top them. There is a unique service launching this year called XStreamHD that is kinda like NETFLIX but delivered to you through satellite and internet. It's full 1080P so it oughta knock your socks off.
How many TV's can operate from a single dish?
Theoretically, ALL of them! Just a matter of if you'll need more switches, etc.
Will they be limited to just one channel for the whole house?
Not at all! The small dishes like DISH NETWORK and DirecTV can support every TV in the home with different programming for each TV. The only ones that are really limited to one TV is the old large dishes that panned across the sky. Even then, one could connect a second receiver but they would only get the channels that are available from the particular satellite that the controlling receiver was tuned into. It was only the costs and limited programming that prevented most people from getting a second receiver with the big dishes. There are smaller dishes that still pan the sky and those would really only be useful for one or two receivers.
Also I remember that the dish would change directions to locate another Satellite in space. Is this still the same?
Most of the dishes you see these days are fixed and don't ever move at all. Many of them have several LNBs on them so they can pick up several satellites at once without having to move. There are still some moving ones out there but I believe they only number in the hundreds of thousands whereas the fixed ones have over tens of millions of customers.
Can I view stations in other countries like Japan and England, ect.
Dish Network and DirecTV both offer international programming. There is also FTA (Free-To-Air). FTA is great for picking up ethnic, religious, and foreign programming. We have a forum here for FTA where you can ask about trying to pick up content from certain countries. Just remember that you have to be within that particular satellite's footprint to pick up programming. So, if you are in the USA and a particular signal is beamed down to England, you won't be able to get that satellite. Also, for FTA, there are unscrupulous people who will talk about getting DirecTV and Dish Network via FTA equipment. This is not true FTA, it is a form of signal piracy. If you have to pay a subscription, then it isn't legal to receive. However, there is lots of truly free programming out there. It's as legal as if you were to put a VHF antenna on the roof to pick up stations off the mountain. In this case, the antenna is a dish.
