TracPhone® FB250 Assembly and Mounting
Instructions for a 19" (49 cm) Dome
The following instructions explain how to assemble the TracPhone
FB250 antenna within the 19" (49 cm) dome, which matches the
TracVision®M5 satellite TV antenna. They also explain how to mount
the dome to your vessel. These instructions are a supplement, not a
substitute, for the TracPhone FB250/FB500 Installation Manual. Be
sure to follow all installation guidelines contained therein.
Tools Required
• Drill with 3/8" (10 mm) bit
•Socketwrenches
• Light hammer; center punch; tape; scriber/pencil
• M3 and M6 allen wrenches
• #2 Phillips screwdriver
Do not remove the radome from the TracPhone FB250 antenna.
The antenna is a sealed unit. You do not need to disassemble the
antenna to mount it within the 19" (49 cm) dome.

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.
Figure 1 FB250 Forward 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.

(“FORE”)
Be sure to ground the antenna to the ship’s hull using the
supplied grounding strap. The 19" (49 cm) dome’s baseplate
and stanchion are not suitable grounding points.

Assembly and Mounting Instructions
Step 2 - Mount the Antenna Assembly
a. Make sure that you have chosen a suitable mounting
location based upon the guidelines in the Installation
Manual.
b. At the mounting site, lay out the four mounting bolt
holes. Make certain that the “FWD” arrow is parallel
with the vessel’s centerline and pointed toward the
bow.

c. Drill the four 3/8" (10 mm) bolt holes in the mounting
surface.

d. Bring the antenna coaxial cable from belowdecks up
through the center of the 19" (49 cm) dome’s baseplate
and connect it to the FB250 antenna’s TNC connector.

e. Position the antenna assembly in place over the holes
drilled in the mounting surface, with the “FORE”
forward reference facing the bow. Ensure all holes line
up.

Connector
The FB250’s “FORE” forward reference must point toward
the bow of the vessel for the antenna to work properly.

f. At each of the four baseplate mounting holes, place a
1/4" flat washer on a 1/4"-20 bolt and insert the bolt
into the hole from above, as shown in Figure 5.

g. Secure each mounting bolt to the mounting surface
using a 1/4" flat washer and a 1/4"-20 lock nut from
below. Tighten all four bolts until the four rubber feet
are bottomed against the mounting surface.
h. Place the radome onto the baseplate and secure in place
with the three #10-24 screws you removed earlier.
i. Install a protective screw cap over each radome screw.
j. Follow the instructions in the TracPhone FB250/FB500
Installation Manual to complete the installation.
