Prepare The Rf Cables - KVH Industries TV3 Installation Manual

Prepare the RF Cables

Follow the steps below before you begin wiring
the antenna.
a. Determine the number of RF coax cables you
need to connect to the antenna for your
particular installation (see Figure 10).
NOTE: A system with a dual linear LNB requires
an additional 50 ft (15 m) RG-6 RF cable with a
sealing boot (KVH part no. 32-0819-50). Spare
right-angle connectors and right-angle boot
extensions are supplied in the kit.
b. Determine the type of RF cable(s) and
connectors required for any RF cables
required in addition to what is supplied in
the antenna kit (see Figure 11). Then follow
the guidelines below to select and prepare the
antenna's RF cable(s).
IMPORTANT!
• RF cables must be rated for 75not 50
• Use of any cables not specified in
Figure 11 will void the warranty.
• Low-quality, poorly terminated, or
improperly installed RF cables are the
most common cause of system problems.
Terminate all RF cables with high-quality
"F" connectors using the proper
stripping/crimping tools, exactly to the
manufacturer's specifications.
• When determining cable lengths, be sure
to account for an adequate service loop,
approximately 8" (20 cm) at both ends of
each cable.
