Please avoid using the antenna length close to that of a half wave or multiple of a half wave in length.
WARNING
●
Never place your antenna in a location where it may come into contact with POWER
LINES. SERIOUS INJURY or DEATH may result if the antenna were to make contact
with power lines.
●
Locate the tuner and antenna in a manner that is not accessible during operation. The
antenna will have high voltage while transmitting.
CAUTION
For operator safety, a good outside earth ground or water pipe ground should always be
installed and connected to the ground terminal of the MFJ-926. Make certain the safety ground
also connects to the transmitter and other station accessories. A wing-nut post marked
GROUND is provided for ground and counterpoise wire connections.
ANTENNA LENGTH
The MFJ-926 Remote Automatic Antenna Tuner will match an antenna of suitable length to any
transmitter. Lower frequencies require longer antennas while higher frequencies require shorter lengths.
The MFJ-926 does have a limited amount of inductance and capacitance and will only match antennas
within its limits. The antenna may be to long if the tuner does not find a match. Simple testing methods
can be used to determine how to adjust your antenna.
OPERATION
After verifying each of the connections to the tuner, choose your desired frequency and switch the
transmit mode as desired. Press the PTT key, the MFJ-926 will automatically tune. You will hear some
“click click” noisy, it means the auto tuner is tuning.
When you go back to the frequency which is tuned before, MFJ-926 will pickup the existing L/C
combination from memory setting and match the system.
To reset the tuner, just simply disconnect the power from the MFJ-926.
