1 What does a satellite system consist of?
A. Dish - LNB - cable - receiver
2 What is an LNB ?What do the numbers mean,i.e 0.3
A. The LNB (
Low
Noise
Block downconverter) converts the signals from electromagnetic or radio waves to electrical signals and shifts the signals from the downlinked C-band and/or Ku-band to the L-band range.
The number is the threshold - the lower the better
3 How big a dish do I need?
A. Depends where you live - the footprint for different satellite and channels vary.
4 What are cams&cam emulators,card readers etc
A. CAM (
Conditional
Access
Modules) used to hold subscriber card for encrypted channels. Emulation software on some receivers can replace them with software that does the same job. Card readers are usually built in CAMS
A. Bar that fits on the back of your dish that has a screw and motor that pull and push the dish to move it.
A. A polar mount is designed to allow all visible geostationary satellites to be accessed by swinging the antenna around one axis (the main axis).
7 Can the CI digital receivers be used for Sky TV and how many other channels in the sky are available?
A. You are better with a Sky receiver for their channels but you can use other receivers like the Dreambox using a Sky card. Thousands of other channels are available other than Sky.
8 Differences between motors,Diseqc,h to h,go to x,36v etc
A. Motors move the dish in different ways H-H (
Horizon to
Horizon) move the dish in one plane. DiSEqC motors rotate and tilt the dish at the same time - limited to dishes up to 1.2m. DiSEqC is a means of sending a signal from the receiver to a motor along the single coaxial cable (Eutelsat invented it). 36v positioners are separate from the receiver and can move larger dishes.
9 List of satellites and what they show
A. Changes daily best start here... _http://www.lyngsat.com
A. A satellite positioner which converts Diseqc 1.2 to 3 amp capable 4 wire control. This enables heavy duty large motors to be used with Diseqc 1.2
11 Longitude and latitude,what it means and why you need them
A. Where you are in the world handy when setting the dish angle and direction. Essential when setting up a motorised system.
Well I tried my best sure someone will correct me if I'm wrong....
