Which ASR-11 beam is the normal radiation beam and is always used to transmit and receive?

Explanation:
The low beam is the normal radiation beam. In the ASR-11, multiple beam patterns exist to suit different scanning needs, but the low beam provides the standard elevation coverage used for everyday surveillance and is the beam that is used to transmit and receive by default. The other beams are special-purpose: the high beam elevates the focus to higher angles for higher-altitude targets, the mid beam covers mid-elevation sectors, and the narrow beam offers tighter beamwidth for higher angular resolution but narrower coverage. So for routine operation, the system transmits and receives using the low beam.
