If you deal with the subject of cables, sooner or later you will come across the terms wire and stranded wire. But what exactly is the difference and what are the advantages and disadvantages? This article takes a closer look at the main features of wires and strands and highlights the different areas of application and their advantages.
What it’s all about: Wire and strand usually describe the inner conductor of a cable through which electrical signals are transmitted. In order to protect the signal transmission and minimise loss over distances, this inner conductor is protected with a sheath and other components. Further information on the structure of a cable, e.g. a coaxial cable, can be found at koax24.de | Structure.

A single inner conductor wire:
A wire consists of just a single conductor, often made of copper or steel. For very thin cables, a steel wire is often used to ensure stability, which is often silver-plated or copper-plated. A copper wire, sometimes tinned or silver-plated, is often used for thicker cables and offers greater flexibility compared to a steel wire.
As a rule, wires are therefore solid and therefore only slightly bendable, making them best suited for fixed installation. The advantages of a solid wire are generally a lower attenuation value and a higher electrical load capacity, which can increase signal transmission and signal quality.

Several individual wires, twisted together – stranded wire:
A stranded wire is an inner conductor with many very thin individual wires. Some of these are only a fraction of a millimetre in diameter and are braided together to form a single inner conductor. This ensures a particularly high degree of flexibility, which increases with the number of interwoven individual wires. Stranded wires are often used in moving applications where the cable is repeatedly bent.
Another advantage of stranded conductors over wires is the reduced risk of conductor breakage. The cable can still be used even if a certain number of the individual wires are broken.
Summary: The correct choice of inner conductor is heavily dependent on the intended application of the cable. However, this should not be the only decisive factor in choosing the right cable. Other factors such as the material of the outer sheath, the insulation and other components of the cable play an important role.
You can’t find the right type of connector for the type of cable that is essential for your application. Who hasn’t encountered this problem? You can easily overcome this challenge with our matching adapters. These help you to combine a wide variety of connector types so that you always have the right solution to hand.
Despite our high standards to provide all suitable connector types for every coaxial cable, it is unfortunately still possible that the availability of your desired connector on the market is limited. This is where our high-quality adapters from various manufacturers such as Telegärtner or Rosenberger come into play. They create a transition between the connector you are looking for and any other connector, which we assemble to your desired cable instead.
If you are unable to find the right connector in our online cable configurator, our experts will of course be happy to provide you with support and help you to realize your requirements. Get in touch with us!
Our passive signal connection box is equipped with BNC sockets as well as a 37-pin D-Sub socket. By default, the signals are all passed on 1:1 to the pins of the D-Sub connector. Signals can also be transmitted over longer distances using a suitable connection cable. The common connection via the D-Sub connector enables the connection cable to be changed quickly without having to disconnect an individual BNC connection.
We offer our breakout box in various standard versions with 6, 8, 12 or 18 BNC sockets. The connection is made via a standard D-Sub female connector or according to customer specifications.

The connection box makes it possible to tap all signals via a BNC socket. Either a standard 37-pin D-Sub cable or a cable whip specially manufactured by us can be used for this purpose.
Corrugated cables with low loss properties, such as the Cellflex® variants, are usually also referred to as semi-flexible cables. In addition to a strong electrical performance, they also have an extremely robust design, which makes them ideal for applications in radio systems. Due to their PE jacket, they can also be used outdoors, where they are used for mobile phone base stations, HD TV and mobile internet, among other things.
A side effect of the special design with corrugated shielding is that this type of cable is only suitable for fixed installation. An application with frequent movement frequency is not compatible with the high bending radius. However, the cables offer excellent technical values, low losses and a high shielding effect.

The standard LMR cables are suitable for a wide range of applications, for example for measurement technology, laboratory use, audio and radio applications, broadband communication and in the automotive sector. The cables can be used reliably at frequencies up to 6 GHz and, thanks to their PE outer sheath, both indoors and outdoors. In our online shop you will find numerous connectors that are compatible with the various LMR cables, but you can also get them pre-assembled according to your wishes using our online cable configurator.
Ultraflex (UF):
The Ultraflex version of the LMR cables is suitable for moving applications with smaller bending radii than regular cables thanks to its stranded inner conductor. They can also be used outdoors and have low-loss characteristics. Our product range includes the UF versions of the LMR-195, LMR-240 and LMR-400.
Fire resistant (FR):
The LMR-FR cables have a fire-resistant polyethylene sheath and comply with the MIL-C 17F standard. They are suitable for installation inside buildings. We stock the FR versions of the LMR-100A, LMR-195, LMR-240, LMR-400 and LMR-600.
Direct Burial (DB):
The waterproof LMR-DB variant has a UV-resistant outer jacket and a waterproof structure. Due to their high weather resistance, these cables are particularly suitable for outdoor use. We have the LMR-400-DB in our range.
FAKRA connectors are mainly used in vehicles to connect GSM mobile radio and GPS antennas for transmitting camera data. As a large number of connections are laid in parallel, we offer plastic coding in up to 11 different colors as accessories for the connectors to virtually eliminate the risk of mix-ups.
FAKRA connectors comply with the DIN 72594-2 standard and are suitable for a temperature range of -40°C to +105°C. They can be combined with the common cable types RG58, RG174, RG316 and RG178, among others.
Assemblies with FAKRA connectors and a matching cable can be put together individually and easily in our online cable configurator. We can realize your requirements at a reasonable price from just one piece. Of course, you can also purchase all FAKRA connectors and coding as individual parts from our online shop.
FAKRA Codierungen
The different colored FAKRA codings prevent a cable from being plugged in incorrectly. This is achieved by differently arranged recesses in the housings, which only fit into each other if the coding is the same color. The only exception is the color “water blue”. This Z-coding serves as a universal connection that is compatible with all other colors.
We only use Rosenberger products for both the connectors and the coding, which are of course processed according to the manufacturer’s specifications.
