<Justification of the extended calibration>
If dipoles are verified in return loss (<-20dB, within 20% of prior calibration for below 3GHz, and <-8dB, within 20% of prior calibration for 5GHz to 6GHz), and in impedance (within 5 ohm of prior calibration), the annual calibration is not necessary and the calibration interval can be extended.

The return loss is <-20dB, within 20% of prior calibration; the impedance is within 5 ohm of prior

calibration. Therefore the verification result should support extended calibration.
