MOUNTING INSTRUCTIONS
STEP1:
Connect the terminal of the ground strap provided with
the spring mount to the chassis of the vehicle for
ground reference.
The terminal is compatible with M6 studs / screws.
Connect the connector of the cable assembly to the N
connector located in the base of the spring mount.
Recommended mating torque is 130N.cm
STEP2:
Secure the spring mount on the bracket or on the
chassis of the vehicle using one of the two following
options:
Option A: use 4 3/8
screws (or eq.) to secure the mount
through 4 holes equally spaced on a ∅
114.3 mm
circle..
Option B
: use ¼ screws (or eq.) to secure the mount
through 6 holes located on a ∅111 mm circle
Refer to the technical drawing of the base for more
details on both options.
Washers should be used to prevent major scratches that
might reduce the mount’s compatibility to salt spray.
STEP3:
Remove the protective cap
located on top of the
spring mount.
Inspect visually the inner
part of the connector of the
antenna to make sure no
sand, dirt or plastic
material will prevent
proper electrical mating.
Screw the antenna tube
onto the spring mount until
it comes a mechanical
stop.
STEP4:
Secure the assembly using the M5 screw sets provided
with the antenna tube.
At least one out of the 3 screws shall be tightly screwed
to prevent un-mating of the antenn
a with shocks or
vibrations.
