User Instructions
DEFINITIONS
LNB: Low Noise Block amplifier. The portion of the antenna dish that receives the
high-frequency signal reflected from the dish and then down-converts it to the
L-band (950-2150 MHz).
IRD: Integrated Receiver Decoder. Also referred to as the set-top box or satellite
receiver. The IRD processes the digital data carried by the RF signal and
provides the baseband picture signal to the television.
RF: Radio Frequency signals
Cable: 75 Ohm coaxial cable
Dish: Oval shaped antenna hardware mounted on the exterior of the customer's
premises.
