AT-100 Active Antenna Owner's Manual
7. INPUT: Either wire antenna or telescoping antenna on the
top cover. (Not both at the same time.) Input is
connected to the spacer where the telescoping
antenna will be used.
8. OUTPUT: SO-239 connector for output to radio receiver.
9. GROUND: Post/Wing-nut type ground connector.
OPERATION
Carefully unpack your AT-100 from the packing carton and inspect it for signs
of damage. If any damage is apparent, notify the transportation carrier or
dealer immediately.
We recommend keeping the packing carton for moving,
storing, or reshipping the tuner.
Installation Procedures
1. You may connect either the telescoping antenna provided or an external
wire antenna of your choice. To connect the telescoping antenna; screw the
antenna end through the top cover and into the spacer located on the PC
board. If you chose to use external wire antenna; plug it into the INPUT
SO-239 connector located on the back of the unit. (DO NOT HAVE
BOTH ANTENNAS CONNECTED AT THE SAME TIME!)
2. Connect a cable from the output of the AT-100 to your receiving equipment.
3. Connect a wire (#18 ga. approx.) from the wing-nut ground to the receiver
ground which, in turn, should be connected to an earth ground. If the unit
is operated in a portable application, this ground need not be connected.
Tuning
1. Make sure the AT-100 BYPASS switch is in the ON position.
2. Select the band and frequency of desired operation on your receiving
equipment.
3. Set the GAIN and POWER controls on your receiving equipment to the
desired settings before applying power to the AT-100. Actual setting may
vary from antenna to antenna.
4. Turn the AT-100 GAIN control full counter-clockwise.
5. Set the AT-100 BAND Selector Switch to the selected band. The red LED
will light.
