Assembly and Mounting Instructions
Step 1 - Assemble the Dome
a. Remove and save the three #10-24 screws securing the
19" (49 cm) dome’s radome to the baseplate. Remove
the radome and set it aside in a safe place. Refer to
Figure 2 on page 3 throughout this procedure.
b. Note the location of the forward (“FORE”) reference on
the base of the FB250 antenna. Knowing the location of
this reference point is very important throughout the
assembly process. You may want to apply a temporary
label to the FB250 radome to better mark the reference.

c. Attach the mounting bracket to the base of the FB250
antenna as described in the instructions provided with
the mast-mount kit.
d. Attach the mast-mount collar to the mounting bracket
using three supplied M4 socket-head cap screws.
e. Insert the blue plastic sleeve into the mast-mount collar.
f. Place the FB250 antenna assembly onto the stanchion
inside the 19" (49 cm) dome’s baseplate.
g. Align the “FORE” reference on the FB250 with the
“Forward” arrow on the 19" (49 cm) dome’s baseplate.
h. Secure the FB250 antenna assembly in place using the
three set screws supplied in the kit.

Be sure to ground the antenna to the ship’s hull using the

and stanchion are not suitable grounding points.
