Justification of the extended calibration Referring to KDB 865664 D01, if dipoles are verified in retum loss(< -20dB, within 20% of prior calibration), and inimpedance(within S ohm of prior calibration), the annual calibration is not necessary and the calibration interval canbe extended. <Head 450MHz> Return Loss (dB) Delta (%)ImpedanceDelta(ohm) Date of Measurement -25.95-45.0-Feb. 21, 2025 -26.25-1.1645.870.87Feb. 20, 2026 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. ※※END OF THE REPORT※※
