75E Antenna Elevation Correction — SB-0013-1.00

Symptom

 

  

The elevation reading obtained does not match the actual elevation scale 

on the 75 cm Elliptical antenna

Possible Cause

 

  

Elevation scale on antenna is off by approximately 2 degrees from 

the Point Dish tool reading.

Recommended Action

 

  

When aligning the antenna, set the initial elevation reading with the 

value from Point Dish. When sweeping the azimuth to locate the satellite, increase the 
elevation in one-half degree increments, until the satellite is found and you have peaked 
the dish for the strongest signal. Example: If the Point Dish elevation reading is 29, it will 
be closer to 31 degrees when you have located the satellite and peaked the dish.
