ARSVCom - Antenna Setup 

4 antenna setups can be defined, and automatically will calculate any offset for each of them. For instance a rotary dipole can be selected, so the appointing will be selected via long/short path. 

It's very normal to use a 90º offset antenna when 2 antennas are too close on the same mast. So the ARSVCOM will use the offset defined for each of them. 

If any antenna is selected as bi-directionability, 2 arrows will be displayed. One the larger arrow display the direct position, meanwhile the short arrow is the 180º position
