The MHA has an operational current 'window' and providing the current consu
window and within the specified DC voltage range, the MHA operates correctl
MHA current consumption is outside this window, an MHA alarm is activated.
An MHA alarm is triggered if the MHA Low Noise Amplifier (LNA) is defective o
operational limits.
Note
If open or high impedance exists along the antenna line supplying the MHA DC
VSWR alarm condition.
