CLEANING INSTRUCTIONS
To clean the antenna, use mild dish washing liquid (one that is not
harsh to the hands and without ammonia) in lukewarm water.
WARNING: Do not let paint solvents, cleaning solvents or adhesive
caulking come in contact with the antenna. Chemicals in these
materials might destroy the finish.
IMPORTANT! Please read all instructions before installing.
TECH TIP:This antenna will
read “short circuit” when tested
with an ohm meter or continuity
tester.
For installations where the
cable exits through the bottom
center of the antenna’s ferrule,
replace the grommet at the
exit hole in the ferrule with
the supplied Grommet Plug.
Remove the Grommet Plug

INSTALLATION INSTRUCTIONS
SELECT A LOCATION FOR THE ANTENNA
Choose a location that is as high as feasible, as free as
practical from obstructions, and as far as possible from
other antennas and strong sources of RF. Cable runs
should be kept as short as possible. If cable length
exceeds 25’, the use of RG-8X or RG-8 A/U coax (sold
separately) is highly recommended, to reduce signal
attenuation caused by the cable.
HOW TO MOUNT THE ANTENNA TO A DECK OR BULK-
HEAD, USING A MARINE MOUNT
This antenna can be mounted self supporting only if
you are using the recommended Shakespeare 4187-HD
stainless steel ratchet mount (sold separately). Use the
1”-14 thread adapter (supplied) to attach the antenna to
the mount. The slot in the side of the thread adapter will
accommodate up to RG-213 size coax cable.
ASSEMBLE THE ANTENNA SECTIONS AS FOLLOWS:
1. Bolt the mount to the deck or bulkhead according to the
directions included with the mount you choose. Be sure
to heed any cautions, included with the antenna mount,
regarding drilling fiberglass surfaces.
2. Thread the 1”-14 thread adapter onto the mount and
hand tighten.
3. Feed the coax through the slot in the side of the thread
adapter or through the bottom and through the hole in
your antenna mount, if one is provided.
4. Install an PL-259 connector (sold separately) for the size
coax that you have chosen, according to the instructions
packed with the connector.
5. Attach the PL-259 connector to the base of the antenna
and tighten securely.
6. Place the rubber O-ring in the groove on the antenna
ferrule.
7. Seat the antenna ferrule on top of the 1”-14 thread
adapter and tighten the coupling ring securely. The
adapter has special facets to prevent the antenna from
rotating once the coupling ring has been tightened.
HOW TO MOUNT THE ANTENNA TO A MAST:
1. Feed the coax through the slot in the side of the thread
adapter or through its bottom.
2. Install an PL-259 connector (sold separately) for the size
coax that you have chosen, according to the instructions
packed with the connector.
3. Attach the PL-259 connector to the base of the antenna
and tighten securely.
4. Strap the thread adapter to the mast using stainless
steel U-bolts, a mast mounting device, or strapping and
appropriate hardware (not supplied).
5. Place the rubber O-ring in the groove on the antenna
ferrule.
6. Seat the antenna ferrule on top of the thread adapter
and tighten the coupling ring securely. The adapter has
special facets to prevent the antenna from rotating once
the coupling ring has been tightened.
COMPLETING THE INSTALLATION
1. Route the coaxial cable to your VHF radio, keeping it
as far as possible from other electrical equipment
and cables.
2. Install a connector (sold separately) that is appropriate
for your size coax and your radio’s antenna connection.
