4 Maintenance
In case of functional errors, check the antenna for possible damage.
Visual inspection
Visual inspection is a basic check to verify that the hardware is not damaged. Check
the driven element, the directors and the reflector and the stabilizer bar for complete-
ness and visual damage.
If one of the elements mentioned is missing, bent, broken or torn off, the antenna has
to be repaired or replaced.
Electric functional test
An electronic functional test requires a network analyzer to measure the VSWR. The
test should be done in an empty room (no interfering, especially metallic, objects as
well as other persons should be present).
In case of a working antenna, the results should conform to the following specifications
in the antenna's specified frequency range (see
Z900",
●
VSWR < 2.5:1
If the antenna does not work as expected, contact the Rohde & Schwarz support.
