Note: The external (post cavity) forward power should be at least 70 percent of the precavity forward
power.
14. Verify the external (postcavity) reflected power is not too high. At the prompt type:
a 79 3 <Enter>
The system displays external reflected wattmeter FM power output reading.
Figure 5-12: External Reflected Wattmeter Reading
Note: The external (postcavity) reflected power should not be more than five percent of the external
forward power. A good antenna system has less than two percent reflected power.
15. Perform one last check of all wattmeters as follows. At the prompt type:
a 80 <Enter>
The system displays the RF-O! transmitter wattmeter readings.
Note: Power readings are only taken during FM Keyups, not during the AM portion of InFLEXion
frames.
