Sea Tel 2400 Dual Band C/Ku

16-6

EAR Controlled - ECCN EAR99

Example: The antenna pictured in the screen capture below is imbalanced so that it is “Front, or

Bottom, Heavy”. The LV trace is plotting above the red line, indicating that CW drive is required

to maintain the current elevation position.

•

The Azimuth display plots below the red line when the antenna is driven CW and plots above

the red line as the antenna is driving CCW.
