Satellite Radio Splitter Kit
This kit includes the adapters, cables, splitter, amplifier(s) and impedance transformers to operate multiple satellite radios from a single standard
antenna and allows the use of standard RG-6 cable for connections. This kit has been designed to maintain the proper RF link budget for the
radios and not degrade the C/N or BER (Bit Error Rate) of the received signal. The splitter loss at 2.35 GHz is overcome by the amplifier(s) gain
located at the input to the splitter. The splitter is power passing on all ports (diode protected) and passes the DC output of the each radio to
power the antenna and amplifiers. For RG-6 cable runs to or from the splitter exceeding 25 feet it is necessary to use additional amplifiers
(Model SBA-1) to overcome cable loss and maintain proper signal levels. (See Figure 1 for guidelines). For cable runs exceeding 250 feet
between the antenna and splitter, the use of Model PS-1 power inserter is recommended to power the antenna and line amplifiers.
Figure 2 shows a typical splitter setup using the accessories provided. All output ports from the splitter must be terminated with the supplied
impedance transformers before attaching the SMB cables to the radio inputs.

RG-6 Satellite Radio Extension Cables ( Kit EXT-1)
Introduction:
This kit includes the connectors and adapters to permit the use of standard RG-6 cable with standard
satellite radio antennas. This kit, when used with the appropriate line amplifier, can extend the antenna
cable up to 125 additional feet for a total of 145 feet. Multiple amplifiers (one for each 125 foot segment)
can be used to make longer cables. This kit provides the flexibility to allow the installer to cut RG-6 cable
to custom lengths and to use plenum rated RG-6 cable where fire codes require. A 3 foot length of small
diameter coaxial cable is supplied with SMB plugs to mate with the radio and an S-band rated line amp..
The amps must be placed as shown in the attached diagrams at the antenna end of the cable to
overcome cable loss.
125 Foot Extension
The attached diagram shows the configuration for a 125 foot extension cable. To overcome the loss of
the RG-6, a line amplifier is required to be located at the end of the standard 20 ft antenna cable.
250 Foot Extension
The diagram shows a 250 foot length of RG-6. This requires the use of one additional line amp located
as shown at the antenna end of the cable for a total of two amps in cascade. Do not locate these amps
at the receiver end of the cable.
375 Foot Extension
The diagram shows a 375 foot length of RG-6. This requires the use of two additional line amps, located
as shown at the antenna end of the cable for a total of three amps in cascade. Do not locate these amps
at the receiver end of the cable.
