Specific Of Operation In Transmission Mode; Power Reduction At Overload - Acom Owner's Manual

4.7. Specific of Operation in TRANSMISSION Mode

Under no circumstances should operation with antenna output SWR above 10:1 be
allowed!
In many cases, the tuner may be able to handle SWR even higher than 3:1 at the antenna output, but if the
protection for antenna overcurrent, overvoltage, forward or reflected power is activated, the operator
should reduce power input to the tuner (e.g., transceiver excitation).

4.8. Power Reduction at Overload

When matching of loads with SWR above 3:1 (up to 10:1) is possible, the maximum allowed tuner power
must be reduced gradually as per
