Receiver Mounting
For mobile repeat using the Marti AR-10 Mobile Repeat Receiver, mount the receiver near the transmitter using the
three fasteners supplied in Mobile Mounting Kit, 700-251.
SRPT-40A and RPT-30
Mobile Remote Control
Remote control of the SRPT-40A transmitter requires a switch to control primary 12-15 VDC power (or 15-30
VDC) and a second switch to control the transmit function. The primary 12-15 VDC (or 15-30 VDC) control
requirement can be met by tapping the ignition switch circuitry of the vehicle. The "transmit" function can be performed
by installing a switch on the vehicle.
FIG. 2A and 2B show the electrical circuit of a mobile installation for 12-15 VDC (585-141) and 15-30 VDC (585-
142), respectively.
Mobile Repeat
Mobile repeat operation is covered under Stationary Remote Broadcast Installation. Electrical connection for a
12-15 Volt supply is made through Mobile Repeat Cable No. 585-139. This cable is connected between the SRPT-40A
transmitter and AR/CR-10 receiver. Power is obtained by connecting the fused RED wire to the 15-30 VDC battery or
supply. The supply must be capable of delivering 10 Amps minimum. The electrical diagram of this cable is shown in
FIG. 3A.
Electrical connection for a 15-30 Volt supply is made through Mobile Repeat Cable No. 585-140. This cable is
connected between the SRPT-40A transmitter and AR/CR-10 receiver. Power is obtained by connecting the fused BLUE
wire to the vehicle 15-30 VDC battery or supply. The supply must be capable of delivering 10 Amps minimum. The
electrical diagram of this cable is shown in FIG. 3B.
Mobile Antenna Installation
One or more mobile antennas are required depending upon the various receive and transmit frequencies and whether
antenna duplexing is used. Antennas are specified in the various system packages listed in the Marti literature. The
installer should follow the instructions supplied with the mobile antennas.
