Connecting Multiple Receivers to One Antenna
Multiple DR500/1 Receivers can be connected to one antenna. However, to avoid
damage to either the antenna LNB and DR500/1 Receiver, the following items must be
used:
•
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 1450 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, or be diode
steered. 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, unless using diode steered splitters. Failure to do so may result in severe
damage to the antenna LNB and the DR500/1 Receivers
The line amplifier should be inserted just prior to the input of the splitter (not after the
antenna LNB). For best performance line amplifiers are typically inserted every 150 feet.
Recommended Equipment
The following equipment is recommended when multiple receivers are connected to one
antenna:
• High frequency splitters
• Channel Master 2212IFD. Two port splitter, diode steered. Not
necessary to disable LNB power from 2
nd
receiver.
• Channel Master 2414IFD. Four port splitter, diode steered. Not
necessary to disable LNB power from any receiver.
• In-line satellite amplifier. Channel Master 5113IFD line amp.
• Coaxial Cable. Maybe necessary to use RG-11 for longer runs, over
300’.
