264 DUMMY LOAD INSTRUCTIONS
The MFJ-264 is a dry air-cooled resistive dummy load. This resistor load is capable of handling
high short-term RF loads. A reasonable cool down period is needed to keep the resistor from
becoming permanently damaged. The cool down period needs to be about 10 to 20 tines the load
usage. The load can be temporarily immersed in clean water to speed up cool down tine.
Thoroughly dry the load by blowing forced air through it before using it again. Never operate
this load while it is immersed in any liquid.
OPERATION
1. Become familiar with the POWER CAPABAILITY curve so that overheating of the
resistor can be avoided.
2. Connect the transmitter to the input of the dummy load. Use a PL-259 connector.
NOTE: Do not let the dummy load resistor get hot enough to glow red. If the dummy
load resistor starts to glow red, turn the transmitter off immediately and allow
