DU 3000 Antenna Tuner
Notes
1. An SWR or 1:1 is best, but an SWR as high as 2:1 may be acceptable. Check
you transmitter manual for details.
2. If you can
’t get an acceptable SWR, lengthen or shorten you antenna and/or
feedlines and retune.
3. If you get low SWR readings at more than one setting, use the setting that:
Gives the highest FORWARD power reading.
Gives the lowest REFLECTED power reading.
Uses the largest capacitance (highest number) on the TRANSMITTER and
ANTENNA controls.
4. Any time a new or different antenna is connected, it is necessary to repeat the
tuning procedure for each antenna.
