4.0 TROUBLE SHOOTING AND MAINTENANCE
4.1
General
Problems in transmission and reception applications can be the result of faulty equipment,
transmission lines or the antenna. If problems occur in the operation of the system, check first
and ensure the problem is not being caused by another piece of equipment or the transmission
line. The AS-1735/SRC can be checked as described in this section.
4.2
Equipment Required
Due to the design of the AS-1735/SRC, trouble shooting tactics are limited to visual inspections
of the various components. The antenna’s internal electrical system contains a DC short to
ground so any continuity tests will always indicate a short circuit. This is normal. Other than a
screwdriver, no special tools are required.
4.3
Typical Troubles
The main area of concern would be the UG-352 connector; check for solid contact on the threads
and that the centre contact is not broken or loose. Symptoms of a poor connector would be
random fluctuations of reflected power during operation or abnormally high VSWR readings.
The AS-1735/SRC is an integrally constructed piece of equipment. The only replacement part is
the UG-352 connector which must be procured from the manufacturer. If the antenna requires
more extensive repair, it must be returned to the manufacturer for complete replacement or repair
(see contact information in Section 6).
4.4
Preventative Maintenance
On a regular basis, i.e. once a month, the AS-1735/SRC antenna should be visually inspected for
rigidity, cleanliness and general condition. At this time, it is also recommended to remove the
UG-352/U connector to check as to whether or not any moisture has formed inside due to
condensation. If so, the connector should be wiped dry and reconnected.
