1 LNB points to one satellite in the sky.
2 LNB's point to two different satellites in the sky.
3 LNB's point to three different satellites in the sky.
For services like Direct TV, each satellite can handle only so many
channels. So when they want to add more channels, then need to put another
satellite up there.
The basic services will be on 1 satellite. And you can receive the basic
services with a dish with just 1 LNB.
(FYI the LBN is the thing at the end of the arm pointing toward the dish.)
Might be easier if you get the same dish with the same numbers of LNB's as
at your home. Or you can go through the setup on your receiver and see if
you can set it for a 3 LNB dish. Older receivers may not have this
capability?
Then find other satellite dishes in your neighborhood and point your dish
the same basic direction and height for a ball park setting.
Then you would make the basic aiming adjustment by going into install or
setup in your receiver, then selecting just the basic LNB, and pointing that
at the correct satellite. This would be a left/right - up/down adjustment.
Then for the other two LNB's (if you are using those for additional
channels), you would tilt the dish clockwise or counter-clockwise to get
those just right (select on of those LNB's for aiming).
The LNB's are typically powered by the coax cable. Different LNB's work
differently with different frequencies. So be sure those LNB's and the "box
which connects them together at the dish" are compatible with your specific
receiver.
Here is where the experts are located on this...
