How to Diagnose High-Frequency RF Output Drop After Installation

A high-frequency output drop after installation may begin at the PA or downstream RF path. Compare corrected Pout, path loss, VSWR, and reference planes.

How to Diagnose a Reflected Power Alarm After C-UAS Installation

A reflected power alarm after C-UAS installation does not prove an RF PA fault. Compare FWD, REV, VSWR, test boundaries, and the installed RF path first.

How to Verify Test Cable Loss Compensation in RF PA Acceptance

Test cable loss compensation can misstate RF PA approval. Check reference plane, raw Pout, correction source, frequency validity, and double-counting risk.

Dummy Load Testing vs Real Antenna Chain Checks

Dummy load testing can prove an RF PA baseline but not the installed RF path. See which reference planes and evidence buyers must compare before approval.

How to Verify Cabinet RF Routing Before C-UAS PA Acceptance

Cabinet RF routing can look correct while the active path, reference plane, or PA/source state is wrong. Verify route evidence before C-UAS acceptance.

Does Feeder Loss Really Reduce RF Power Amplifier Gain?

Feeder loss can cut antenna-input power without reducing module gain. See where the loss occurs before rejecting, overdriving, or oversizing the RF PA.
