Antenna Assembly Instructions
Please follow the steps listed below to assure proper operation of this antenna and deploy as
described.
Step
Assembly Operation
1
Remove all items from the Carry Bag and inspect each item for any damage.
2
Identify and count all parts, comparing them to the Parts List.
3
Determine how you will physically mount the antenna, whether you purchased one of
the Alpha Antenna mounting options or have one of your own.
4
Attach the
Outer Loop Element
by laying the Alpha Match depicted in Figure 1 on a flat
surface, then attach (screw) the PL-259 connectors on the Outer Loop into the SO-239
connectors on the Alpha Match.
5
Setup the tripod on a flat stable surface and screw the Tripod into the bottom of the
Alpha Match, again it is better to turn the tripod rather than the Alpha Loop Jr.
6
Mount the completed Alpha Loop Jr Antenna by positioning it in a location where it
cannot touch other objects such as lamps, desks, poles, wires, power lines, ladders,
people, etc.). Your deployed antenna should now appear as depicted in Figure 2.
7
Now it is time to connect the antenna to your radio. If your radio has a SO-239, use the
included BNC to PL-259 adapter to attach the Feed Line to your radio, otherwise attach
the BNC connector to your radio.
Antenna Operation
The Alpha Loop Jr antenna has a built in tuning knob on the Alpha Match. It is with this black
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 Jr in nearly all scenarios:
1)
After attaching your coax to your radio, turn the tick mark on the Inner section of the
Brass Reduction Drive so that it points in relatively close proximity to the frequency
range marked on the Alpha Match.
a.
Please note that the capacitor can turn past 360 degrees without damaging any
component.
b.
Also note that you can tune from 7 through 29.7 MHz on either side of the
marked frequency designation.
2)
Now power on your radio/antenna analyzer on and to the frequency you would like to
operate; IF ATTACHED TO ANTENNA ANALYZER SKIP TO STEP 5.
