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.
The Sat Buddy 2
™
satellite meter measures relative RF signal strength when
connected to a dish antenna. It is designed for installing and maintaining typical DBS
residential satellite systems. The Sat Buddy 2
™
also measures LNB current and the
voltage being supplied to the LNB. It can power LNBs and multi-switches using its
internal battery or allow IRD power to run through it.
Each Sat Buddy 2
™
package contains:
•
Sat Buddy 2
™
meter
•
Protective rubber boot with clip
•
Wall plug transformer for charging battery
•
Cigarette lighter adapter for charging battery in automobile
