Introduction:
Times Microwave Systems offers TRAD™ and NuTrac™ radiat-
ing cables to provide RF coverage in structures which are other-
wise difficult to cover. Conventional examples include rail and
transit tunnels, underground mines, subways, metal-hulled ships,
offshore oil rigs, nuclear power plants and buildings with metal
supporting structures.
Multi-point, antenna based communications systems are unable
to provide uniform RF coverage. In order to provide adequate
coverage, many service providers increase the power levels to
unacceptable levels. This problem can be overcome with the use
of radiating cables instead of point source antennas. These
cables act as continuous antennas, and are designed to emit RF signals at very low power levels.
These low power levels reduce the potential for interference with other nearby systems using the
same frequencies and allow for frequency reuse. Examples are the creation of mini-cells within a
building and low-level roadside AM broadcast systems.
Other advantages of radiating cables are their ability to carry multiple frequencies on a single cable,
and to function as a single broadband antenna. The radio frequency signals are fed between the
transmitter and antenna and a controlled amount of energy is leaked into the surrounding environ-
ment which provides the needed RF coverage. The radiating cable is designed to both receive and
transmit RF signals in the surrounding controlled environment across this single broadband antenna
cable.
T-RAD Leaky Feeder Cable:
Times Microwave offers the T-RAD series of flexible, low-loss leaky feeder cables. This design pro-
vides a cost effective solution where point source antennas are not practical. The T-RAD cables uti-
lize a continuous single slot design, which is achieved by bonding a metalized shield to the low-loss
foamed polyethylene core. This foamed core/shield design yields a very flexible lightweight design,
which allows for easy installation. The slot opening is designed to provide a balance between down-
line signal attenuation and coupling loss. It’s broadband design allows it to be used from lower
frequency AM/FM radio rebroadcast through the higher frequency 802.11 WLAN applications.
There are currently two different jacket versions available with the T-RAD cables. The standard
T-RAD cable utilizes a flexible PVC outer jacket while the T-RAD-FR series utilizes a non-halogen,
low-smoke flame retardant jacket. Both designs exhibit excellent flexibility, and provide very cost
effective installation methods.
A wide range of connector styles are available for the T-RAD cables. The T-RAD-400 and -600 sizes
were designed to accept the Times LMR EZ-style crimp connectors. A special thinner crimp ring is
required to properly crimp the outer ring to the connector body. Reference the section for proper
connector attachment procedures. For the T-RAD-900 size, the standard LMR EZ style clamp
connectors are used.
nu-TRAC Radiating Cable:
Times Microwave also offers the nuTRAC radiating cable series to address applications where
longer runs of cable are required. Typical applications are long road tunnels, metros and subway sys-
tems. The nuTRAC series of cables are larger cables that offer lower down-line signal attenuation
while still providing adequate RF coverage within the surrounding environment. This delicate bal-
ance of attenuation and coupling loss is achieved by the isolated overlapping shields that are separat-
ed by a thin polyethylene interlayer. The coupling mechanism between the inner and outer shields
provide for controlled RF coverage. This transfer of energy between the two shields results in a
design that exhibits relatively little sensitivity to the surrounding environment and its mounting
effects. This design feature provides for a cable that is easier to install and reduces the concerns of
mounting which results in an overall lower cable installation cost.
Times offers two jacket options for the nuTRAC series. For applications that do not require flame
performance the standard nuTRAC is used, which employs a UV resistant polyethylene jacket. For
applications that require flame performance, the nuTRAC-FR series would be used. The outer jacket
on the –FR cables is a non-halogen, low-smoke and flame retardant polyolefin material. Many metro
and subway applications require the use of non-halogen materials, as well as providing higher levels
of flame performance.
