GENERAL
INFORMATION
INTRODUCTION
The MT-3 / MT-4 repeater system is a VHF /
UHF radio system which is characterized by
high performance and reliability under the most
severe environmental conditions. The total
system is designed to provide dependable, low
maintenance performance, even in the most
diffi cult circumstances.

The MT-3 / MT-4 series of modules are
packaged in the compact Euro standard
(5”h x 2.8”w x 7.5”d) housing, and are robustly
designed for urban, remote or transportable
applications. Voltage stress testing is done over
the range of +11 to +16 VDC which is followed
by 24 hours of continuous operation at maximum
rated power output.

When the VT-3 / VT-4 transmitter is used as
an exciter for the VHF AMP-2 power amplifi er
(PA) module, it will provide an adjustable 20 to
30 W RF output over the 136 - 174 MHz VHF
frequency range.

frequency range.
The VHF AMP-2 family contains three models
(AMP-2/145-30, AMP-2/155-30, AMP-2/170-30)
covering three frequency bands 136 - 150 MHz,
150 - 162 MHz and 162 - 174 MHz respectively.
The VHF AMP-2 power amplifi er (PA) mates with
either of the MT-3 / MT-4 VHF transmitter exciter
modules (the VT-3 transmitter exciter module or
the VT-4 transmitter exciter module).
