SSB

The Style 6390 is a Phase III® series HF/SSB Marine antenna of 18’ 4” overall
length, including the 1”-14 thread adapter. The two-section, side-fed antenna has
stainless steel ferrules and a side feed termination stud. Its conductors run the full
length of the antenna sections, and the antenna’s insulating properties will support
input power up to 1 KW. The design of the Phase III antenna series facilitates
mounting to a mast or attachment to a standard marine mount.

Select a location for the antenna.

Choose a location that is 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.

How to mount the antenna to a deck or bulkhead, using a marine mount:

The recommended mount is a Shakespeare Style 409-R or 410-R Stainless
Steel Mounting Kit (each sold separately). Use the 1”-14 thread adapter (supplied)
to attach the antenna to the mount.

Assemble the antenna sections as follows:

1. Remove the tape that holds the tip section of the antenna to the base section

during shipping.

2. Inspect the O-ring to be sure it is seated in the bottom groove of the base

section’s upper ferrule. Thread the tip section onto the base section’s upper
ferrule and tighten.

Mounting the Antenna to deck or bulkhead:

1. Use a Shakespeare Style 409-R or 410-R Mounting Kit (each sold separately)

to install the antenna on your boat. Install the mounting kit’s stand-off bracket
at least 4 feet above the antenna’s base where possible. Follow the directions
included with the mount you choose.

2. 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.

3. Thread the 1”-14 thread adapter onto the mount and tighten.

4. Proper ground plane (counterpoise) is necessar y for maximum per formance of

the antenna. It is suggested that a qualified marine technician be used, to insure
proper installation.

5. Place the rubber O-ring in the groove on the antenna ferrule.

6. 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. Strap the thread adapter to the mast
using stainless steel U-bolts, a mast
mounting device, or strapping and
appropriate hardware (not supplied).

2. Place the rubber O-ring in the groove
on the antenna ferrule.

3. 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. Follow the radio manufacturer’s
instructions for connecting the
antenna to your SSB equipment.
