Cable connections
NOTE:
Connect a user supplied coaxial cable to the appropriate antenna connector if the transceiver has more than one. See
your transceiver’s instruction manual for details.
Example: IC-7300

Ground connections
The ground wire of the antenna tuner is used as an antenna
element. The transceiver and antenna tuner must have
an adequate ground connection. Otherwise, the overall
efficiency of the transceiver and antenna tuner installation
will be reduced. Interference, RF feedback, and electrical
shocks from other equipment could also occur.
For best results, use the heaviest gauge wire or strap
available, and make the connection as short as possible, as
shown below.
L
A long wire connected to the GND terminal as a counterpoise is
also acceptable.

WARNING!
Mount the AH-730 securely with the
supplied nuts and bolts. Otherwise, vibrations and
shocks could loosen the antenna tuner, making it fall,
causing personal injury.
CAUTION: DO NOT
mount the

Waterproofing the antenna connection
CAUTION:
If you skip the following steps, moisture will
get into the connector, and this could damage the antenna
tuner.
CAUTION:
•
NEVER
modify, bend, twist, pull or heat the control cable and the coaxial cable.
•
NEVER
hang something heavy on the control cable and the coaxial cable.
•
NEVER
mount the AH-730 without securing the control cable and the coaxial cable so that they cannot be pulled or
stretched.
1. Cut off just the top of the weatherproof cap, and pass
the antenna wire through the cap.

2. Insert the antenna wire into the opening of the crimp-on
wire terminal.
L
Crimp or solder the antenna wire.

3. Put the crimp-on wire terminal, star washer, and wing
nut on the base nut, in that order, and then tighten the
wing nut.
L
Make sure the base nut is tightened firmly before you
tighten the wing nut, as shown below.

Carefully bend the wire terminal up after you tighten the
wing nut. (

4. Place the weatherproof cap over as much of the
insulator as possible. (

L
How far down it will go depends on the height of the wing
nut.
5. Start wrapping the rubber vulcanizing tape at the bottom
of the insulator, then the weatherproof cap, and finally
the antenna wire to prevent water seeping. (

Wrap user supplied electrical tape over the rubber
vulcanizing tape to secure waterproofing.
