• Make sure the mounting surface is wide
enough to accommodate the antenna’s base
(see Figure 5). Also make sure it is flat, level
(within ±1°), strong enough to support the
antenna’s weight, and rigid enough to
prevent antenna vibration.
• Be sure to preserve enough free space outside
the access hatch to allow a technician to
remove the hatch and perform maintenance.
• Select a location that is not too high above the
waterline (less than 1/2 the vessel’s length),
and as close as possible to the intersection of
the vessel’s fore-and-aft centerline and
midships.
• Be sure to mount the antenna near enough to
the TV-Hub to allow you to connect the 100 ft
(30 m) coax cable between them, while still
maintaining sufficient slack in the cable.
NOTE: For RF1, you must use an RG-11 cable. If
you need to use a longer cable, use a RG-11 (75

)
cable that does not exceed 200 ft (60 m) in length (see
“Prepare the RF Cables” on page 8 ).
