GPS L1 Inline Amplifier
The GPS L1 Inline Amplifier (570704-0002) option boosts the signal from the
antenna. Use this amplifier on LMR-400 cables that are longer than 650 feet; it
receives power from the GPS radio receiver through the antenna coaxial cable
connections. Table C-5 provides mechanical and electrical specifications for the
amplifier.
