Characterizing and Verifying Antenna Systems
Typical Measurements
Typical Measurements
The following typical measurements are used to characterize the
antenna feedline system and help identify problems:
• Before installation—incoming inspection
–cable return loss
–characteristic impedance
–velocity factor
• Installation—baseline tests
–insertion loss
–antenna return loss (SWR)
–feedline system return loss (SWR)
–fault location
–length
• Maintenance—compare to baseline
–antenna return loss (SWR)
–feedline system return loss (SWR)
–fault location
