2.0 Maintenance
Before performing any maintenance,
follow the safety information in the
ETS-Lindgren Product Information
Bulletin
included with your shipment.
Maintenance of the Model 3160 Series is
limited to external components such as
cables or connectors.
If you have any questions concerning
maintenance, contact ETS-Lindgren
Customer Service.
 When not in use, the Model 3160 Series Pyramidal Horn Antenna
should be stored on a shelf face down to keep dust out of the feed
areas.
 If the Model 3160 Series is used outdoors, the antennas should be
checked for water accumulations. Water has a high dielectric constant
and can alter performance.
 If an antenna is dropped, the feed/horn joint should be checked for
misalignment.
Annual Calibration
The electromagnetic performance of the Model 3160 Series is almost exclusively
dependent on the physical dimensions of the horns. Comparisons with
computed gain and antenna factor result in differences within 1 dB. Therefore, it
is not necessary to calibrate Model 3160 Series antennas; only a mechanical
check is required to guarantee performance. However, if calibration is required,
see the Product Information Bulletin included with your shipment for information
on ETS-Lindgren calibration services.
