The Style 407 Heavy Duty 4-Way Swivel Mount is a
versatile antenna mount made of chrome plated br ass. Its four-
way swivel action permits easy lowering of the anten na to clear
overhead obstructions. The mount is not self-suppor ting and
must be used with a Shakespeare Style 408-R Sta ndoff Bracket
(sold separately). Standard 1”-14 threads.
Tools required: Drill, drill bit for 1/4” wood or
sheet metal screws, screwdriverInstallation
Instructions
1. Choose a mounting location that is as high as possible, as fre e
as possible from obstructions, and as fa r as possible from
other antennas.
2. Using the mount’s base plate as a template, mark the locations
for the four mounting holes. Drill 1/4” mounting holes.
Note: When drilling berglass, u se metal
drilling bits, not wood boring bit s. If possible,
support the surface with a wooden backup pad
during drilling, to mi nimize push-through
damage.
3. Assemble the Swivel Mount by joining the two sections and
securing them with the hex-head bolt, lockwasher, and nut
(supplied). Note that this joint can be in one of two positions,
according to whether you’re mounting to a vertical or
horizontal surface.
4. Attach the mount assembly to the mounting su rface using
machine screws, lockwashers, and nuts (sold separately). For
some types of surfaces, you might need to su bstitute stainless
steel woodscrews or other hardware.
5. Attach the antenna to the Swivel Mount, being caref ul not to
damage the antenna’s cabling, if any. Fit the antenna into your
upper support bracket (sold separately) and secure it.
IMPORTANT: If the thickness of the mounting
surface is not adequate to support the antenna
under expected stress, a wooden back-up pad
(not supplied) should be applied underneath the
mounting surface during installat ion.
