PRODUCT DESCRIPTION
The PA1-1AEL model is a mobile VHF low band RF power amplifier intended for use in the mobile
applications. This amplifier can deliver RF power from 60 to 110 W when driven with 2 to 4 W and it
will cover the frequency range from 29.7 - 36 MHz. The mobile amplifier is designed to be installed in
the interior of a car or in the trunk. The amplifier’s dimensions are: 11.6"L x 3.0"H x 5.5" W
(see figure 1) and the weight is 5 lbs.

OPERATION MODE:
FM / CW
OPERATING VOLTAGE:
Nominal DC operating voltage is 13.8VDC and the specifications are
given at this voltage. However, the minimum DC operating voltage is 11 Volts and the maximum DC
operating voltage is 15 Volts as measured at the VDC input connector. Reduced DC input voltage will
result in lower output power and efficiency.
EIA DUTY CYCLE:
WITH NO EXTERNAL COOLING:
110 W Output (FM) 
30% duty cycle
NOTE: Use of TPL Mobile Amplifiers above the recommended duty cycle or in repeater
applications is not recommended and voids the warranty.

OPTIONS
TPL Communications’ Low Band VHF Mobile Power Amplifiers are available with several options:
input, output, frequency ranges and configurations, special logos, etc., when specified at the time of
order. We work closely with you, our customer, to develop products that are in complete compliance
with your needs and specifications.
CAUTION!
Inspect the amplifier thoroughly upon receipt for visible damage. If any is noticed, please call TPL
Communications at 800 HI - POWER to request an RMA (Return Material Authorization) number. If
purchased through a dealer or distributor, ask them to also follow this procedure for best results.
EXPENSIVE COMPONENTS MAY BE DESTROYED IF THE AMPLIFIER IS TURNED ON
IN A DAMAGED CONDITION

FCC CERTIFICATION
TPL Communications commercial amplifiers are FCC certified for the use in Land 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.
Harmonics, and other spurious, signals from this amplifier are attenuated according to or beyond
FCC requirements. For further details consult the appropriate publications.
OPERATING PRECAUTIONS
CAUTION:
This amplifier produces RF voltages that can cause painful and dangerous burns. Use caution!
Connect and disconnect all RF connections with the drive power and DC power off.
DRIVE POWER:
RF power transistors, although quite rugged in most respects, are easily damaged by
overdrive. Be careful not to overdrive the amplifier even momentarily (before applying any
drive signal please check table I for details). Higher-than-rated drive power may destroy the
transistors and VOID ANY WARRANTY.
SUPPLY VOLTAGE:
The maximum operating voltage is 15VDC. When using the DC power supply make sure
that it is not adjusted above 15 volts. If it is possible for the voltage to go above 15 Volts for
any reason, including failure of the power supply, install a “crowbar” circuit to 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 accidentally be placed over it. Keep duty
cycle below limits.
TERMINATIONS:
The efficiency of this amplifier will degrade if it is operated into anything but a 50 Ù load.
Lowered efficiency may mean any or all of the following: lower power output, increased
current drain, higher operating temperature, and reduced life time.

INSTALLATION
The PA1-1AEL amplifier installation is illustrated in figure 2. Mount the amplifier as close to the antenna
as practical. Keep coaxial cable runs short, avoiding sharp bends and pinching. Avoid loose connectors
at the ends of the coaxial cables. 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.
1. Mount the amplifier away from the sources of heat, and where air can freely circulate around it.
Avoid mounting the amplifier in the engine compartment or near the exhaust pipe system.
It is also important to securely fasten the unit. An improperly mounted piece of equipment is
subjected to damage as it moves about and can cause serious injuries in an accident. Use bolts
through the holes in the amplifiers flange to fasten the unit to a secure mounting surface (see
figure 2).
Figure 2. Amplifier installation
2. Wire the DC power connector (Cinch 4 pin female) directly to the battery if possible. Do not use
the present vehicle wiring. Use #10 AWG if possible and certainly no lighter than #12 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 table I.
Attach DC input wires in accordance to the diagram in figure 3. If wires are too large for the holes,
solder them to the sides of the blades.

3. Connect the antenna to the “RF OUT” terminal with a 50Ù coaxial cable and a PL-259
UHF male connector according to figure 4.
4. Turn off your radio transceiver. Connect it to the “RF INPUT” terminal with a 50Ù coaxial
cable.
