3.1 

   Limits of Normal Operation 

 
The antenna is designed to perform optimally within these operational limits: 
 

Random vibration 

1.05 g rms with the following spectral density 
5-20 Hz………….0.02G2/Hz 
20-150 Hz……….-3dB/octave 

Single frequency vibration 

5-10 Hz with amplitude 2.54 mm 
10-15 Hz with amplitude 0.76mm 
15-25 Hz with amplitude 0.40mm 
25-33 Hz with amplitude 0.23mm 

 

3.2 

   Absolute Maximum Limits 

Exposure outside these limits may cause permanent damage: 
 

Temperature 

-45 to +60 °C
