Using A Remote Antenna
The optional ANT 005 Coaxial Antenna is intended
for use with rack-mounted transmitters or in
installation areas where a remote antenna is needed
for maximum operating distance.
Per FCC Rules, only antennas supplied by Williams
Sound may be used with this transmitter.
Do not cut or alter the antenna cable before
reading the instructions below!
The ANT 005 Coaxial Antenna is a length of coaxial
cable with an "F" connector on one end and an
80-inch antenna built onto the other end. The last 80
inches of the antenna make up the active element,
which is covered by nylon braid. The active
element should never be altered. The remainder of
the antenna cable is RG-59 coax feedline. The
feedline can be shortened if you have the tools to
install a new F-connector. If you need a longer
feedline, extension cables are available from
Williams Sound in 50 foot lengths (WCA 008 50).
Never splice coax cables together. Always use
proper connectors.
Installing The Remote Antenna
Step 1: Remove the “rubber duckie” antenna from
the T20’s top panel by turning it
COUNTER-CLOCKWISE.
Step 2: Use a pliers to remove the cap on the
connector. Be sure to turn COUNTER-
CLOCKWISE to remove the cap.
Step 3: The ANT 005 Coaxial Antenna connects
to the “Antenna” connector on the rear
panel of the T20 Transmitter. To attach the
cable, making sure the center wire on the
cable enters the hole in the center of the
receptacle. The connectors screw together
and need only be “finger-tight.”
Remote Antenna Location Guidelines
For maximum signal strength, it is best to select an
antenna location somewhere within the listening
area. The preferred location is towards the front of
the listening area and above the seats. The active
element (nylon braid covered portion) should be kept
straight, not coiled, and must be vertical.
Radio signals will generally pass through non-metal
structures. The antenna can be mounted on a wall, in
a corner, or behind a wooden beam. It may also be
hung vertically from the ceiling, with a small weight
attached to the end to make it hang freely. If you
need to run the feedline through a wall, a 1/2" hole is
necessary to pass the connector through.
Avoid placing the antenna within four feet of steel
beams or near structural steel elements. Metal
studs, ductwork, and foil-backed insulation can
absorb radio energy, greatly reducing the range
of the system. DO NOT put the active element
(last 80 inches) inside a metal conduit. The
feedline is categorized as Class II wiring. Thus, it
may be (but is not required to be) routed through
metal conduit, but NOT with microphone cables
or AC power wiring.
Nylon clamps and screws are provided to attach the
Coax Antenna to a wall. Locate the clamps every 3 -
4 feet. DO NOT bend the cable sharply at any point.
Allow at least a 3" radius for turns. DO NOT staple
the cable in place. Use the cable clamps provided or
hang the antenna from the excess nylon braid at the
end of the antenna element.
