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 ®
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

2
nu-TRAC ®
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

3
Tunnels/Rail-Transit:
Times Microwave supplies both the nuTRAC and T-RAD-
600 cables for a wide variety of tunnel applications. The
T-RAD-600 cable has been used to provide communications
for the PATH rail tunnels at the World Trade Center site in
New York City. T-RAD-600 is used as a backbone to provide
radio frequency coverage throughout the mile long rail
tunnels between New Jersey and lower Manhattan. A
cascaded amplifier system offsets the attenuation and cou-
pling losses, which are characteristics of all leaky feeder
systems. The nuTRAC series has been used extensively in
the New York City subway system to provide police radio coverage, in the London
Underground system to provide a wide range of RF coverage and in the Moscow and St

Petersburg metro system’s to provide Tetra, GSM900 and UMTS coverage

In-Building Communications
T-RAD-600 cable successfully provides broadband
coverage in building applications for VHF, UHF,
cellular, PCS and 802.11b WLAN frequencies

Typically this cable is run through a building, where
point source antennas are not practical. The T-
RAD’s flexible lightweight design allows it to be
routed easily for quicker and more cost effective
installation. With the use of cross-band couplers a
single T-RAD cable backbone can support multiple
use frequencies. In addition to in-building applica-
tions, the cable has been utilized by many utilities to
provide broadband RF coverage

Offshore Oil-Rigs:
Times Microwave has supplied the T-RAD-600FR series
to the offshore oil-rig industry. The multi-deck layout of
many oil rigs combined with many shadowed areas, cre-
ates a difficult environment in which to obtain consistent
radio frequency coverage with single point antennas

T-RAD cables have been utilized to provide deck to deck
broadband RF communications coverage, and elevate
coverage in the dead spots which are common in such
an environment. The jacket material used on the –FR series cables is a flame-retardant, non-halo-
gen, low-smoke material, that provides an increased level of safety, which is always a concern for off-
shore applications

4
Mining:
T-RAD-600 leaky feeder cables are used to provide underground
communications for a wide variety of mining applications. The
cable is run throughout the mining tunnels and allows a
controlled amount of signal to leak into the surrounding
environment. This enables the
cable to receive and transmit,
where radio frequency coverage
is required. T-RAD cable can be
run into splitters, providing a
means to run leaky feeder cable
into any shadowed or cross-tun-
nel areas. Times maintains
MSHA mining approvals for
both its T-RAD-FR (MSHA
Approval #07-KA070009P)leaky
feeder cables, as well as its
LMR-FR (MSHA Approval
#07-KA070010P) series of low-loss coaxial cables

Perimeter Detection Systems:
Times Microwave supplies T-RAD-600DB cable for direct burial
detection system applications. This cable provides coverage
around highly sensitive areas that require added security, such
as prisons, nuclear facilities and military installations. The
T-RAD cable radiates a signal creating an EMF field, which
when disturbed by an intrusion alerts security personnel. The
added water-blocking material and dual jacketed outer polyeth-
ylene jacket of the DB series, allows this cable to be directly
buried where perimeter routing is required. This application
provides an undetectable RF perimeter around the monitored
location

Commercial and Military Shipbuilding:
Much like the offshore oil-rig applications, many
of the same coverage issues that plaque RF design-
ers are also found in shipbuilding applications

Many large vessels have multi-deck designs, with
many enclosed stairwells and shadowed areas

With the use of the T-RAD and nuTRAC designs,
RF engineers can design a layout to provide the needed radio coverage aboard ship. From relatively
low frequency VHF applications to applications where 2.4 GHz WiFi coverage is need, these cables
can offer broadband controlled RF coverage
