Use this information to help you to solve some of the typical problems that you may encounter when using a Real Freedom Active UHF Splitter in a Real Freedom Fiber system.

Table 1. UHF splitter troubleshooting
Symptom Possible cause Actions
Poor RF signal. Cable runs too long.
  • Ensure that you minimize the required cable lengths and RF signal loss by installing the UHF splitter close to the receivers and fiber base unit.
RF levels too low.
  • Use the receiver’s Fiber & Splitter menu to add a gain boost into the splitter system. Note that if you add a boost when RF levels are not too low, you can overload/saturate the system.
Issues with the downconverters connected to the fiber remote unit.
  • Check the placement of downconverters attached to the fiber remote unit.
  • Verify there is no mismatch of antennas. All downconverter and transmitter antennas should match your band of operations.
  • Check downconverters are powered.
Poor or no fiber signal from the remote unit to the base unit.
  • Check that all fiber connectors are securely fastened.
  • Remove the fiber connections and clean the glass tip. Reconnect and verify the signal.
  • Check that fiber is connected to the correct ports on both the fiber remote and fiber base units (S to S and D to D).
  • Turn off power to the receiver's RF ports carrying fiber.
  • Change the fiber cable.
