OPERATING TEMPERATURE RANGE: -30° to +60° Celsius
OPERATING VOLTAGE: Minimum 11VDC, Maximum 15VDC
as measured at the DC Input connector. Rated voltage is
13.8VDC and all specifications are given at 13.8VDC. Reduced
DC voltage will result in a decrease in power output.
NOMINAL CURRENT DRAIN: 14 AMPS. Standby current is less
than 3 mA.

General Specifications
(cont.)
RECEIVER PATH INSERTION LOSS: 1dB maximum (150-174 MHz)
HARMONIC AND SPURIOUS EMISSIONS ATTENUATION:
Models meet or exceed FCC requirements.
CONNECTORS: S0-239 (UHF) on input and output. Cinch 4 pin
(male) DC input.
**FUSING: If an external fuse is required, refer to the table under
General Specifications.
NOTE
This amplifier has been tuned to the frequency specified at the time
of order. Broader coverage is available, if specified at the time of
order.
CAUTION!
Check the amplifier upon receipt for visible damage. if any is noticed, please call TPL at (800) HI-POWER for an RMA number (Returned Material Authorization): If purchased through a dealer, or distributor ask them to follow this procedure for best results.
EXPENSIVE COMPONENTS MAY BE DESTROYED IF THE
AMPLIFIER IS TURNED ON IN A DAMAGED CONDITION.
TYPE ACCEPTANCE
TPL Communications commercial amplifiers are FCC Type
Accepted for use in the Land and Marine mobile/fixed services. The
technician installing this amplifier must hold a General Radio Telephone
permit and be familiar with the pertinent FCC rules and regulations.
Harmonic and other, spurious, signals from this amplifier are attenuated beyond FCC requiements. The amplifiers will stay within specifications even if de-tuning is necessary to reduce power to station imposed limitis .
For further details consult the appropriate publications.

AMPLIFIER INSTALLATION

INSTALLATION
Amplifier installation is illustrated in Figure 1. Mount the amplifier as
close to the antenna as practical. Keep coaxial cable runs short,
avoiding sharp bends and pinching. The antenna should be matched
to an SWR better than 1.5:1 for best results. Higher SWR will degrade the performance of the amplifier.
Mount the amplifier away from sources of heat, and where air can
freely circulate around it. In mobile applications, avoid mounting the
amplifier in the engine compartment or near the exhaust pipe system.
In any mobile installation it is important to securely fasten the unit.
An improperly mounted piece of equipment is subject to damage as
it moves about and can cause serious injuries in an accident. Use
bolts through the holes in the amplifier flange to fasten the unit to a
secure mounting surface.
Wire the DC power connector (Cinch 4 pin female), for the amplifier,
directly to the battery if possible. Do not use the present vehicle
wiring. Use #12 AWG if possible and certainly no lighter than #14
AWG. To avoid a possible fire, or other possible damage, make sure
a fuse or circuit breaker is installed at the battery end of the wire.
Use the same size as the internal fuse listed in the specifications.
Connect the radio transceiver to the “RF INPUT” terminal and the
antenna to the “RF OUTPUT” terminal on the amplifier, with 50 Ohm
coaxial cable and UHF connectors. Terminating information for the
DC connector is given on the following pages.
This amplifier produces sufficient power to cause significant heating
of low quality, or incorrectly selected coaxial cable and fittings. Use
high quality cables and fittings to reduce heating and power losses.

DC CONNECTOR WIRING
Attach DC input wires
in accordance with this
diagram. If the wires
are too large for the
holes, solder them to the
sides of the blade.
OPERATING PRECAUTIONS
CAUTION: This amplifier produces RF voltages that can cause painful and dangerous RF burns. Use caution! Connect and disconnect
all RF Connections iwth the DC power and drive power off.
DRIVE POWER: RF power transistors, although quite rugged in most
respects, are easily damaged by overdrive. Be careful not to overdrive this amplifier, even momentarily. Higher than rated power drive
may destroy transistors and VOID THE WARRANTY.
SUPPLY VOLTAGE: The maximum operating voltage is 15 Volts
DC. When using an AC power supply, make sure that its output
voltage is not adjusted above 15 Volts DC. If it is possible for the
voltage to go above 15 Volts DC for any reason, including failure of
the power supply, install a “Crowbar” unit. This will prevent damage
to the amplifier in the event of excess voltage.
CASE TEMPERATURE: High power can mean high temperatures.
Mount the amplifier where air can freely circulate over it and where
clothing, blankets, etc, will not accidently be placed over it. Keep
duty cycle below limits.
TERMINATIONS: The Amplifier parameters will degrade if it is operated into anything but a 50 Ohm load. That may mean any, or all of
the following: lower power output, increased current drain, higher
operating temperature, lower efficiency and reduced lifetime.
