2. Connect the attenuator output to a
suitable load with 50 ohm coaxial ca-

which mate with the RF output
connector of the attenuator.
3. Follow the transmitter manufacturer’s
instructions.

Note: If the attenuator is to be operated at both
maximum power and frequency values, use a
Male LC connector with a suitable cable (RG-
218/U or RG-220/U) on the input and Male N
connector with appropriate cable or load on the
output. These connect to the RF fittings nor-
mally supplied.
Before applying any RF power to the attenuator, be certain
to check that the vent plug is in place in the vent hole. Refer
to the Installation Chapter.
Normal
Operation
WARNING
The vent plug must be used at all times when the unit
is in operation or cooling. Failure to do this could
result in damage to the equipment and endanger the
operator’s safety. Be sure to check the plug.
WARNING
Using this attenuator in the upper end of its power
dissipation range will cause the housing to become hot.
Care should be exercised in touching it.
CAUTION
This equipment is designed for operation in a
horizontal position only, with mounting brackets down.
Do not operate in any other manner.
CAUTION
RF power rating must always be cut in half when the
blower assembly is installed but is not running. Under
this condition a 2 kW attenuator will be limited to
approximately 1 kW.
