Using A Remote Antenna With The T18 Transmitter
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.
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. The cable connects to the "Antenna"
connector on the rear panel of the T18 Transmitter. Make sure the center wire on the cable enters the hole in
the center of the receptacle. The connectors screw together and only need to 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 may 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.
