I have installed many RRU 8873HP B40 L2300 TDD, but what I see is that there is always one port with a high VSWR value of 1.47. Is there any calibration or command that can solve this problem? The hardware (antenna/jumper/RRU) is in good condition.
A VSWR of around 1.47 on one port usually means there’s a mismatch on that path, even if the hardware looks fine. There’s no special calibration or command that fixes it. The best steps are to recheck the jumper, connectors, and swap the feeder to see if the issue follows. If the mismatch stays on the same port, it’s likely an internal RRU port issue.
