MFJ Dummy Load

model MFJ-260C

The MFJ-260C Dummy load is a dry, air cooled, resistive dummy load. This resistor load

is capable of dissipating RF power without the bulk or mess of oil or other coolants. It is

capable of handling up to 300 Watts for a short period of time. For added convenience a

derating curve is shown below and on the end plate of the dummy load.

Operation

1. Become familiar with the duty cycle derating curve so that over heating of the resistor

is avoided.

2. Connect the transmitter or amplifier to the input of the dummy load with a PL-259

connector.

3. Always allow a 2 to 3 minute cool down when operating the dummy load at it's

maximum duty cycle ratings.

NOTE: Do not let the dummy load overheat. If the dummy load resistor overheats it may

be damaged. Allow the dummy load to cool before touching it.
