RF Harmonic and
Spurious
Suppression
Meets or exceeds ETSI requirements
VSWR!operation!
Up to 1.5:1. Proportional foldback threshold from 1.5:1. Continued operation with
foldback to infinite VSWR. Protected against sudden short and open-circuit
conditions with mute to remove sustained arcing conditions, at all phase angles.
