There are 3 connections located at the bottom of the
power amplier:
1. 12 VDC power input
2. RF input via TNC connector
3. RF output via N-Type connector
The connectors should only be nger-tight. Using tools can
over tighten and damage the RF and power connectors.
A 13.8 V power supply capable of providing a constant
10 amp to the amplier is required. Amplier operation
with insufcient voltage can lead to higher amplier
operating temperatures. Insufcient current can cause the
amplier to not amplify or only partially amplify the RF
signal. These conditions result in incomplete or no RTK
transmissions being received by the vehicle.
IMPORTANT: Make sure the antenna and coax
are attached before the amplier module is
powered ON or damage to the amplier could

occur. Do not remove the coax or antenna
while the amplier is powered ON. Avoid
water intrusion by keeping the connections
attached whenever possible.
Make sure the power connector is attached
and unpowered when handling the RF IN and
RF OUT connectors. The ground provided by
the power connector protects the amplier
against possible electrostatic discharge.
