The distribution networks of today are exposed for ingress from other communication
networks as LTE, 3G, 4G etc and this means that the coaxial cables have to fulfil very high
screening demands to be able to protect the systems from this type of ingress. Choosing
Macab’s triple shielded coaxial cable gives you a top of the line cable with copper inner
conductor and a very high screening efficiency.
Inner conductor
Classification:
In drop cables the most common used conductors are
electrolytic copper (CU) or copper clad steel (CCS). The CCS
conductor can be used thanks to the radio frequency signal
is carried only on the surface of the conductor (skin effect).
CCS has much higher loop resistance than the CU conductor
and that is a very important factor when the cable is used for
remote powering.

Foil
The first shield consists of a polyester aluminium foil bonded
to the dielectric which guarantees 100% coverage. The foil is
mainly for preventing ingress of high frequencies. Depending
of the thickness and the overlap of the foil different shielding
efficiencies will be achieved.
Dielectric
Gasinjected foam is the latest technology for producing
the dielectric of coaxial cables. A nitrogen gas is physically
injected into polyethylene (HPDE) which produces a foam
with excellent mechanical and ageing performances.
Braid
Shielding
To increase the shielding efficiency you can add a braid. If the
braiding coverage is 40% you can reach an efficiency of appr
75 dB. Higher braiding coverage will increase the shielding
efficiency. The braid gives better shielding performances for
lower frequencies. The efficiency is complex and depends of
many different parameters such as how many strands you
are using in the braid, the diameter of the strands, number
of groups of strands, the length of the twisting and what
material you are using.
The shielding is introduced to protect the RF signals from
external interferences. The shielding can be made in several
different ways as single, double, triple and quad. The most
common solution today is the triple shielded. The way to test
and measure the shielding efficiency is defined by EN50117
and the methods are Transfer Impedance for low frequencies
(<30 MHz) and Screening Attenuation for higher frequencies.

Foil
The LSNH, halogen free jacket, is a type of jacket that
doesn’t generate halogens, have a low smoke emission and
is flame and fire retardant when burning.
An extra foil as outer shielding increases the shielding
performance specially for the high frequencies and it’s also
an extra protection for moisture.
Packaging

For your convenience we can offer you different type of
packaging.
Depending in which environment you are installing the
cable you have several different type of jacket to choose in
between.
