Question: What is the considered uncertainty value for a directional probe antenna (e.g., horn, LPDA) with peak gain > +5dBi when using the same cable configuration for both test stages in OTA antenna performance conformance testing?
Option 1: ±0.5dB
Option 2: 0.00dB
Option 3: ±1.0dB
Option 4: Dependent on the specific antenna type
Explanation: According to OTA antenna performance testing principles, using an identical cable configuration across all test stages with a directional probe antenna (peak gain > +5dBi, e.g., horn or LPDA) introduces systematic and constant uncertainty. This scenario warrants an uncertainty value of 0.00dB, reflecting the controlled conditions that minimize measurement variability.
