Why is there high VSWR or reflected power in my BIRD Measuring Instruments?
High VSWR or reflected power in your BIRD Measuring Instruments may be due to several factors. Check for foreign material in the line section or RF connectors and clean them. Inspect the transmission line for opens or shorts. Also, inspect the load, antenna, and connectors for any faults or poor connections.
What to do if I see intermittent meter readings on BIRD Thruline 4304A?
If you're getting intermittent or inconsistent meter readings on your BIRD Measuring Instruments, there are a few things to check: * First, clean the DC contact. * Next, inspect the transmission line or antenna for faults. * Finally, the meter itself might be defective and need replacement.
How to troubleshoot no meter reading on BIRD Thruline 4304A Measuring Instruments?
If your BIRD Measuring Instruments show no meter reading, possible causes include: * Lack of RF power. Check the RF source. * The element might be pointing the wrong way. Rotate the element to the correct orientation. * The meter might be burned out or damaged.
