MOUNTING INSTRUCTIONS
▪Connect the satellite trunk cables to the Trunk Amplifier
▪Connect an earth ground wire to a grounding block
▪Adjust the slope and output level attenuator using the adjustable
dial. The LEDs will indicate the status
▪All non-used RF ports require external termination with 75 Ohms
▪The power supply shall be a PI29 Power Inserter
▪Connect the PI29 Power Inserter to the PWR IN port
▪All Satellite Output Ports are DC blocked. Device does not pass
DC voltage to the output ports
▪The Trunk Amplifier can power an additional device, for example
an upstream Polarity Locker, via the Satellite IN 1 PWR OUT or via
the dedicated PWR OUT Port
▪The Trunk Amplifier can not be used as a polarity locker
▪The Trunk Amplifier shall not be exposed to direct outdoor
elements and is suited for indoor installation only. Outdoor
installation only advised in combination with an approved
outdoor lock box
