Bias Tee Information
The MFJ-4117 Bias Tee is included with the MFJ Remote Tuner. Since the
coaxial cable is supplying the DC voltage to the remote tuner (injected in the
coaxial cable by the Bias Tee), the coaxial cable used must have a good DC
path. Lightning protectors that block DC cannot be used.
Follow the instructions provided by MFJ for both the Tuner and the Bias
Tee.
Make certain the coaxial cables are properly connected to the Bias "T" as shown. Ensure the
ON/OFF switch on the Bias "T" is turned ON when using the system.
NOTE: Review the MFJ Remote IntelliTuner™ manual for a detailed
explanation of the Remote IntelliTuner™ and the Bias Tee operation.
Installing the Bias Tee incorrectly may cause damage to your radio.
