Allnet ANT-CAB-RSMA-RSMA-300 WLAN.eu Antenna Cable LMR-195 R-SMA (m) R-SMA (f) 300 cm content_copy

The Allnet antenna cable ANT-CAB-RSMA-RSMA-300 is an LMR-195 cable with a length of 300 cm, specifically designed for use in wireless networks. It connects an R-SMA plug to an R-SMA socket and is used for transmitting high-frequency signals between wireless devices and external antennas. The cable is suitable for use in WLAN systems in the 2.4 GHz and 5 GHz frequency bands, with signal transmission ensured by low attenuation of approximately 0.95 dB at 2.4 GHz and approximately 1.50 dB at 5 GHz. These values are critical for signal quality and range in wireless networks, as excessive attenuation can lead to signal loss and reduced wireless range.

Applications
This cable is typically used in professional and industrial environments where stable and reliable wireless connections are required. Examples include WLAN infrastructures in companies, public institutions, or industrial settings. Outdoor use is possible due to the materials and temperature resistance, with the cable designed for temperatures from -40 to +85 degrees Celsius. The high mechanical stability and black, halogen-free PUR jacket ensure good resistance to UV radiation and chemical influences.

Functions and Features in Detail
The cable features a solid copper conductor with a diameter of 0.97 mm, ensuring efficient signal transmission. The insulation consists of SPE (special modified polyethylene) with a diameter of 2.67 mm, providing good electrical insulation and mechanical stability. The outer conductor consists of an aluminum foil covered with a tinned copper braid, offering 85% optical coverage. This braid protects the cable from electromagnetic interference and provides high shielding effectiveness. The jacket is made of PUR (polyurethane), has a diameter of 4.95 mm (±0.2 mm), and is halogen-free, increasing safety in case of fire.

Technology Explained Simply
The attenuation values of 0.95 dB at 2.4 GHz and 1.50 dB at 5 GHz indicate how much signal strength is lost during transmission over the cable. The lower the attenuation, the better the signal transmission. Materials such as the copper conductor and tinned copper braid ensure high electrical conductivity and shielding. The SPE insulation provides good electrical insulation and is resistant to moisture. The PUR jacket is flexible, resistant to mechanical stress and UV radiation, making the cable suitable for indoor and outdoor use.

Compatibility and Accessories
The cable is compatible with devices using R-SMA connectors, particularly in WLAN systems. It can be connected to various antenna types that also feature R-SMA sockets. Use in combination with external antennas allows targeted alignment of radio radiation and extended range. The specified frequency bands (2.4 GHz and 5 GHz) indicate that the cable is suitable for most modern WLAN standard applications.

Installation and Mounting
During installation, the specified bending radius must be observed: 15 mm for single bending during installation and 75 mm for repeated bending. Violating these values can cause mechanical damage to the cable and impair signal transmission. The cable is suitable for indoor and outdoor use, with temperature resistance from -40 to +85 degrees Celsius enabling broad application. Installation typically involves connecting the R-SMA plugs to the respective devices and antennas.

Operational Advantages
The combination of low attenuation, high shielding effectiveness, and mechanical robustness ensures reliable signal transmission. The use of a halogen-free PUR jacket increases safety in case of fire, as no toxic gases are released. The black color allows for discreet integration into existing installations. The 300 cm length provides sufficient flexibility for positioning antennas and devices without requiring additional extensions.
