• Correct splitter(s)
• Proper line amplifiers
Line amplifiers may be required when using a signal splitter and/or when
long coaxial cable runs are required from antenna to receiver. All splitters
and line amplifiers should be rated for satellite IF processing with a
minimum bandwidth of 950 MHz to 1750 MHz.
Since power is delivered to the LNB and line amplifier by the DR500
Receiver (18 VDC via RF IN connector), splitters should have one DC
power passing port. All other ports must block DC or have equivalent
circuitry that only permits one of the DR500 Receivers to power the LNB.
Never
connect via power passing splitters. Additionally, the receivers
not delivering power to the LNB should have their LNB power output
switched OFF using Preset 160. Failure to do so may result in severe
damage to the antenna LNB and the DR500 Receivers.
The line amplifier should be inserted at the antenna LNB for cable runs in
excess of 150 feet. For extra long cable runs over 500 feet it may be
necessary to power the LNB with an amplifier/LNB supply within 100 feet
of the LNB.
Recommended Equipment
The following equipment is recommended when multiple receivers are
connected to one antenna:
• High frequency splitters
-
QINTAR HFS-2 and HFS-4. Two and four port splitters that
pass power from one port.
-
QINTAR HFS-2WB and HFS-4WB. Two and four port 5 to
2050 MHz wide band splitters with a built in zener diode
circuit to protect DC return back to the DR500 Receiver. These
splitters can be used in installations requiring power passing to
only one port.
• In-line satellite amplifier
-
QINTAR LA-2050. This line amplifier has a bandwidth of 10 to
2050 MHz. It is typically powered by the DR500 Receiver
