Coaxial
The principle of the Coaxial Cable is based on the high frequency signal being transmitted along the electromagnetic field existing between the inner conductor and the outer shield which share a common axis (hence co-axial).
The dielectric on insulation, the physical size of the conductor and the type and construction of the shield all play a part in determining the electrical performance of the finished Coax cable.
The main standards influencing commonly used coax are the military standard MIL-C-17F or RG Type cables and the Uniradio metric styles on URM types in this section you will find the TV Relay, Satellite TV Coax Cables together with RG and URM Types.
Signum Flexible “Low Loss” coaxial communications coaxial is designed for use in wireless system applications ,short feeder antenna runs or jumper assemblies , they are double shielded and more flexible than corrugated cables with much lower losses than traditional “RG” style coax. Signum coax is available with FireFighter LSZH sheath for Indoor/Outdoor applications or PE sheath for use outdoors , they are available as 50Ω as standard but are also available in 75Ω for video applications in CCTV. CATV ,baseband or broadband , satellite applications or any other 75Ω wireless application.

High performance Low Loss range suitable for TV, satellite and video applications – CCTV , CATV , baseband or broadband . Far more flexible than any corrugated solution This versatile range is available in a number of sizes with FireFighter® Low Smoke Zero Halogen sheath according to IEC60332-3-24 as standard. PE sheathed and steel wire armoured versions are available on request.

With 50 Ohm Coaxial Cables being the best compromise between high power handling AND low signal attenuation (Loss), practically any application that demands high power handling capacity will use 50 Ohm Coaxial Cable. A good rule of thumb is that any device that functions as a transmitter or transceiver tends to use 50 Ohm Coaxial Cable. This includes devices such as CB/Ham Radios, Broadcast Radio/TV Transmitters, Wi-Fi and Cellular Phone Repeaters and 2-Way Radios (Walkie Talkies).
We supply and stock a wide range of popular 50 Ohm Coaxial Cables. RG-58 50 Ohm Coaxial Cable provides acceptable performance for most applications.
There are instances where cables must withstand extreme temperatures (i.e. up to 200 degrees Celsius), such as military and aerospace applications, in these applications PTFE Teflon insulation is used .These high-temperature coaxial cables can handle extreme changes in temperature time and time again.
For installations where protection against mechanical shock e.g., direct burial or rodents is required, DataGuard armoured coaxial cables offer maximum performance.
Our coaxial cables are available in outer jackets of PVC, PE (duct grade) or FireFighter® LSZH which have low smoke emission without poisonous gases. LSZH FireFighter cables are the preferred choice when installing in public places where human life and valuable materials and equipment need to be protected.

75 Ohm Coaxial Cables ensure that the signal gets through the cable in the most efficient way possible, losing very little signal strength in the process. If the device being connected via coaxial cable is a receiver of some kind, 75 Ohm Coax is ideal. This includes devices such as Satellite and Cable TV Receiver Boxes, High Definition Televisions and AM/FM Radio Receivers.
The combination of low attenuation and capacitance effectively make 75 Ohm Coaxial Cable ideal for practically all types of digital audio, digital video and data signals. This is why every cable TV company uses 75 Ohm coax for distributing its digital video channels as well as its broadband internet data signals. Direct broadcast satellite dishes and over-the-air HDTV antennas also require 75 Ohm Coaxial Cable to ensure that all of the digital channels transfer down the cable with the lowest loss and distortion possible.
For installations where protection against mechanical shock e.g., direct burial or rodents is required, DataGuard armoured coaxial cables offer maximum performance.
Our 75 ohm coaxial cables are available with LSZH FireFighter materials which are the preferred choice when installing in public places where human life and valuable materials and equipment need to be protected.
We also stock connectors (i.e. BNC) with matching impedance in our connectors and accessories area of the website.

Digital signals generally look like a square wave instead of the typical sine wave seen with analogue signals. Capacitance tends to “store” the peaks of the square waves, skewing the shape of the square to look more like a straight line. When this happens, the receiver has trouble reconstructing the signal after it has travelled down the coax. Technically 93 Ohm Coaxial Cable has the lowest capacitance of any type. RG62 is a low loss 93 Ohm coaxial cable suitable for use on video, RF signal, antenna and broadcast transmissions.

Premium Low Loss RF Feeder transmission line family is backed by a complete line of user-friendly accessories common to both the copper and aluminium outer conductor, these cables provide a reliable solution when used as backbone feeders in cellular radio systems, including GSM, UMTS, CDMA, PDC and LTE, as well as WIMAX. Other common uses for this family include the cabling of antenna arrays, radio equipment interconnections and jumper assemblies. The foam dielectric cables combine flexibility with high strength and superior electrical performance and are extremely light
Range includes 1/4” to 1-5/8”, Corrugated or Superflexible, provide users with a perfect match for the most complicated and demanding applications.
