TUNE USING GRAPHS & CHARTS IN THE MANUAL
Final tuning may be accomplished by using a transmitter capable of low power with a VSWR mismatch and an impedance bridge. A signal generator may be used with an impedance bridge before connecting the transmitter. Depicted in previous slide is the Delta Electronics RG4 Signal Generator and the OIB-3 Impedance Bridge. If using a transmitter, the OIB-3 bridge may be left in line with between the ATU and the transmitter for tuning and operational monitoring.
