Introduction
This publication refers to the Termaline Load Resistors
Models 8401, 8402, and 8404. The difference between
models is listed in the specifications. These models will
generally be referred to as a load throughout this manual.
Purpose and
Function
These loads are portable, general purpose 50 ohm coaxial
RF transmission line terminations. They are selfcontained units requiring no outside power source or additional equipment. They provide an accurate, dependable,
and practically nonreflective termination for testing and
adjusting RF transmitters operating in the stated frequency band.
Some examples of the uses of these loads are:
As a substitute antenna.
s
s For tuning RF transmitters - under nonradiat-
ing conditions.
s
For making routine tests and adjustments.
s As a substitute for any 50 ohm circuit loading
element.
Description These models are rectangular in shape with transverse
fins encasing an oil-dielectric-filled coolant cylinder. Extra
thick fins at the front and rear are bent 90° to form bottom mounting flanges. These flanges are supports for free
standing use or brackets for fixed mounting. Flange holes
are provided for this purpose. A retractable handle is recessed in the radiator fins.
Performance
Characteristics
and Capabilities
The loads can absorb and dissipate up to 600 W of RF
power continuously. They show a VSWR of 1.1 to 1.0
from dc to 1000 MHz, 1.2 to 1.0 from 1000-2800 MHz,
and 1.3 to 1.0 from 2800-3000 MHz.
Dimensions and
Power and Utility
Weight
Requirements
All three models have the same dimensions: 16-1/16
inches L x 5-15/16 inches W x 8-1/2 inches H (408 x 151
x 216 mm). They each have a net weight of 19.6 lb (8.9
kg) and a shipping weight of approximately 25 lb (11.34
kg).
These load resistors are passive devices that are self contained and do not require a source of power or utility

service to perform their function, other than the RF input
power.
Environmental
Requirements
The load should be operated in an environment as free of
dust and vibration as possible. For proper operation the
ambient temperature should remain within the range of
-40°C to +45°C (-40°F to +113°F). Allow at least 12
inches (304.8 mm) of clear space around the load to provide an unimpeded flow of convection air currents for
adequate heat dissipation.

Theory of Operation
General The Models 8401, 8402, and 8404 Termaline Load Resis-
tors consist essentially of a carbon film-on-ceramic resistor immersed in a dielectric coolant. The resistor,
individually selected for its accuracy, is enclosed in a special exponentially tapered housing. This provides a linear
reduction in surge impedance directly proportional to the
distance along the resistor. When surrounded by the dielectric coolant, the characteristic impedance is therefore
50 ohms at the front (connector end), 25 ohms at the
mid-point to compensate for the resistance already passed
over, and zero ohms at the rear where the resistor joins
the housing, forming the return conductor of the coaxial
circuit. This produces a uniform and practically reflectionless line termination over the stated frequencies for the
load resistor.
Cooling The dielectric coolant is chosen for its desirable dielectric
and thermal characteristics. Cooling of the load is accomplished by natural fluid and air convection currents. The
0.7 gallon of dielectric coolant carries the electrically generated heat from the resistor to the walls of the cylindrical cooling tank. This tank is encased in a set of
radiating fins constructed from heavy gauge aluminum alloy and firmly pressed onto the cylinder. The heat from
the dielectric fluid is transferred to the surrounding air
by the fins.
Expansion of the coolant, caused by the rise in its temperature, is allowed by means of a synthetic rubber diaphragm (not visible) inside the rear cover dome of the
unit.

Installation
Location
CAUTION
The load is designed for operation in a horizontal plane
only, with mounting brackets down. Do not operate in
any other position.
Install the Termaline Load Resistor in a location that:
1. Has sufficient room to provide at least twelve
inches (304.8 mm) of free space around and
above the unit.
2. Is the shortest possible distance, or cable length
from the transmitting equipment.
3. Ensures the operation of the load in a horizontal
position only, with the handle on top.
Mounting The load may be used for portable operation or for fixed
installation, that is, it may stand free or may be secured
to a bench or any convenient flat surface. The front and
rear fins are made of heavier gauge material bent outward 90 degrees to form mounting flanges. At each corner of these flanges is a rubber bumper foot attached
with an acorn nut. To fasten the load by means of its
base mounting flanges:
1. Remove the four rubber bumpers
2. Fasten the load with four screws. Put one screw
in each of the four 9/32 inch holes.
Note: Use screws up to 1/4 inch diameter.
The holes are arranged in a 5-1/8 x 12-17/32 inch rectangle (130.2 x 318.3 mm).

Operating Instructions
Use and
Function of
Controls
Adjustments
Because these are passive devices, there are no operating
controls on the Load Resistors.
Initial
No initial adjustments are required other than to connect
the load to the RF source by means of a coaxial cable
equipped with a suitable matching connector plug.
Start-up 1. Connect a Male type plug, which mates with the
RF input connector, to the load.
2. Connect the load to the transmitting equipment
under test with 50 ohm coaxial cable.
3. After the transmitter has been connected to the
load, proceed according to the transmitter manufacturer’s instructions.
When reconnecting the antenna, it may be necessary to
slightly readjust the transmitter due to possible differences in VSWR between the load and the antenna system.
Normal
Operation
WARNING
When power is in the upper range of the load’s
capacity, the radiator will become hot - care should be
used in touching the equipment.
Operating Under
Emergency,
Adverse, or
Abnormal
Conditions
Having no indicators or controls, these loads require no
special operating procedures or surveillance when properly used.
CAUTION
Do not operate this equipment continuously above the
rated 600 W. Load failure will result.

Shutdown Because the loads are passive devices, there is no way to
turn them off. Power must be shut off at the source of
the RF energy.
Emergency
Shutdown
WARNING
Do not attempt to disconnect these loads from the
coaxial cable while RF energy is still being applied.
Leaking RF power is a potential health hazard.

Cleaning
The principle maintenance required by the operator will
be the cleaning of the radiator fins. Periodically wipe
away the accumulated dust and lint. If the insulator or
metallic contact surfaces of the connector should become
dirty or grimy, wipe them off with a soft cloth and use a
contact cleaner that is self drying and leaves no residue
to clean the inaccessible internal parts.
11

Bird Series 8400S Termaline Coaxial Load Resistor
Inspection With the rugged and simple construction of the Load Re-
sistors, periodic inspection will be necessary at only about
six-month intervals. Inspection should include the items
listed below:
1. Oil Leakage - Check for coolant oil seepage
around the radiator tank, particularly at the
front and back around the underside of the
clamping band.
2. Inspect the Load for completeness and general
condition of the equipment.
The Troubleshooting Chart lists the symptoms of commonly encountered troubles, their causes, and suggested
corrective measures. Use this chart as a guide when analyzing symptoms.
Preventive
Maintenance
Because of the basic simplicity of construction, no special
maintenance procedures are required. Keep the equipment clean, and occasionally check the coolant level in
the radiator tank.
DC Resistance Check the condition of the load resistor by accurate meas-
urement of the dc resistance between the inner and outer
conductors of the RF connector. Use an ohmmeter with
an accuracy of 1 percent or better at 50 ohms for this
purpose. The measured resistance should be a nominal 50
ohms, ±2 ohms. Perform this test only when the load has
cooled down to room temperature. Refer to figure 1.

There are no special techniques required for the repair or
replacement of components in the loads. A screwdriver is
the only tool needed.
RF Connector
Replacement
Diaphragm and
Coolant Oil
The connector is a patented “Quick Change” design.
This process does not interfere with the essential coaxial
continuity of the load resistor RF input or the coolant oil
seal.
For replacement, proceed as follows:
1. Remove the four 8-32 x 5/16 inch round head
machine screws from the corners of the RF connector.
2. Pull the connector straight out of its socket.
Remove the diaphragm to replace or examine the coolant
oil. Replacement of the diaphragm and coolant are listed
in the steps below:
1. Stand the load vertically, with the back end up.
Brace it carefully to avoid tipping it over.
2. Loosen the clamp screw until the clamping band
is released.
3. Remove the diaphragm cover and lift the diaphragm from the back end of the radiator tank.
Inspect the diaphragm. It should be soft and pliable. If it has hardened or shows signs of surface
cracks, replace it.
