MFJ-1020C Active Antenna Owner's Manual
4
6. Turn the BYPASS switch off.
7. Increase the GAIN Control to approximately midway (12 o'clock).
8. Rotate the TUNE Controls for maximum noise or signal as heard on your
receiver.
9. You will notice that pushing the BYPASS Switch to the "ON" position while
listening to a station bypasses the gain and selectivity stages of the MFJ-
1020C. This will decrease the received noise level. Turning the bypass back
"OFF" will raise the level of received signals which will be determined by:
(A) GAIN CONTROL ADJUSTMENT
(B) TUNE ADJUSTMENT
(C) PROPER BAND SELECTION
10. With some antennas connected externally to the MFJ-1020C, a high GAIN
setting may make the unit appear to chirp or whistle as the TUNE is rotated.
Turn down the GAIN adjustment until these are removed or disappear.
Notes
1. Connection of the AC Adapter automatically disconnects the internal battery.
2. Use a Heavy Duty 9V alkaline battery.
3. Use only the amount of gain needed to receive the desired station.
4. Never use an external antenna and the telescoping antenna at the same time.
