Antenna Cable

The most common use of aerial cables, also known as coaxial cables, is to carry antenna, satellite or even cable TV signals to a TV set. For television antennas, cable TV networks, video transmission, mainly 75 ohm impedance cables are used, while for wireless data transmission, transmitting antennas, transceiver devices, 50 ohm versions are usually used.

With a good quality, ideal antenna cable, metal objects around the wire will not cause any loss of performance and external electromagnetic noise will not interfere with the signal. Therefore, these types of wires can be used easily and well in almost any environment.

Types of antenna cables we offer

There are three main types of antenna cables in our range. The first is 50 ohm coaxial cables, which are commonly used for amateur radio, between transceivers and antennas. The second is the 75 ohm coaxial cable, used for analogue TV (antenna) and video signal transmission, but also for transmitting signals from AHD cameras to camera recorders. There are also WiFi antenna cables, which are used to connect a WiFi antenna to a WiFi device.

50 ohm antenna cables

Among the 50 ohm antenna cables, RG-174, RG-58, H-155, H-500 or H-1000 are the most popular types. All these designations are product names of a particular manufacturer, which have become so well established that other manufacturers have since adopted the same designation. There are, of course, some manufacturers (SSB, Draka in our range) who use their own designation, but their cables can also be matched with the above designations. Each cable can be fitted with a different outer diameter, bending radius and connector. Their pitch is progressively more favourable in the order of listing, i.e. smaller. In practice, this means that a lower signal loss is to be expected over 100 m of cable length. This also requires the use of connectors of the right quality.

75 ohm antenna cables

75 ohm antenna cables are typically used for one-way communication, i.e. for TV, DVB-T antenna, cable TV reception, SAT satellite reception between the equipment and the antenna. They also include the transmission of analogue system video signals such as AHD, HD-TVI, HD-CVI and PAL system signals. These aerial cables therefore allow signal transmission over a wide frequency range, so they can deliver high quality picture and sound to the TV set.

WiFi antenna cables

Different WiFi devices may have different connections and antenna connections, which is why cable converters with different connectors are needed to ensure ideal signal transmission. These are typically pre-fabricated cables, as the miniature nature of the connectors means that they can hardly be assembled by hand.

Construction and characteristics of coaxial cables

Coaxial cables can be divided into 4 separate parts.

Shielding layer

Most commonly, braided copper shielding is used, which has the great advantage that it can be easily bent without causing any damage.


Several types of insulation can be distinguished:

  • Polytetrafluoroethylene
  • Polypropylene
  • Polyethylene

Inner core

The inner core can be twisted or solid, made mainly of copper for good conductivity. It is important to note that if the conductor will be subjected to higher than average mechanical stress, it is recommended to choose copper-coated steel as the inner conductor, as steel has even better mechanical parameters than copper.


Coaxial cables are usually coated with soft PVC because this material has the best composition both chemically and in terms of durability.
