Information
                                    The MSR 4030 is a 1 kW antenna coupler for use when
connecting whip or wire antennas to a transmitter designed
to match a 50 ohm load from (j5j)30 MHz. Although
particularly suitable for use with Mackay transmitters
incorporating the MSR 1020 1 kW Linear Power Amplifier, an
optional model MSR 6408 control unit is available to
facilitate interface of the antenna coupler with other
transmitters.

The MSR 4030 is designed for easy installation and features
an automatically switched series capacitor to provide the
capability of matching a wide range of antennas without use
of optional external networks or internal field adjustments.
Additionally, all the high reliability electronic control
circuits are located in a compartment adjacent to the tuning
circuits. This "single package" concept eliminates the need
for a separate electronics unit and simplifies installation
and troubleshooting. The MSR 4030 uses plug-in modular
construction and can be quickly disassembled with only basic
tools. Built in Test Equipment (BITE) facilites are provided
for testing and maintenance of some assemblies without
special test equipment.

The Antenna Coupler is housed inside a fully gasketed and
water-tight case. In this way, it is designed for outside
mounting near the antenna.

A memory module is provided to expand the capabilities of
the basic coupler tuning functions. With this module, the
tuning information can be stored automatically and retained
in memory for up to 96 communication channels. Upon command,
the memory will rapidly guide the MSR 4030 tuning elements
to their preset positions without an RF carrier or any
manual tuning controls. This feature provides extra
convenience and a very rapid method of tuning many
frequencies without the necessity of radiating RF power.

The Antenna Bypass Kit is available as an option that can
provide the user with a convenient method of receiving out
of band signals. It is designed to bypass the coupler
network during receive so that the tuned circuits will not
degrade out of band received signals.

Although the MSR 4030 is designed to withstand severe shock
and vibration conditions, an optional shock mount kit is
available for additional protection. With this kit, the
coupler can withstand the severe shock and vibration of the
environment as defined by MIL-STD-81OC.
