Antenna Operation - Alpha Antenna Alpha Loop Sr User Manual

Antenna Operation

The Alpha Loop Sr antenna has a built in tuning knob, which is black, on the Alpha Match, as
depicted Figure 1 above, and other images as well. It is with this knob that you tune the
antenna to the lowest SWR of less than 1.9:1 on any frequency from the 10 Meter through the
40 Meter band. The following technique has proven to be the easiest method for tuning the
Alpha Loop Sr in nearly all scenarios:
1) After attaching your coax (per Step 14 above), turn your radio on and to the frequency
you would like to operate, then adjust the volume so you can hear it while standing at
the antenna.
2) Turn the black knob on the Alpha Match till you hear the loudest noise level coming
from the speaker on the antenna.
