The DELOCK antenna cable (manufacturer's part number 12498) is a coaxial connection cable for high-frequency applications, made of RG-174 cable with a length of approximately 3 meters. It connects devices equipped with BNC and SMB connectors, for example in radio technology, antenna systems, or measurement and transmission technology. The cable features a BNC connector at one end and an SMB connector at the other, with both contacts gold-plated to ensure a stable and corrosion-resistant electrical connection. The black cable jacket has a diameter of approximately 2.7 mm and is suitable for indoor use as well as in protected outdoor areas, provided there is no direct exposure to weather conditions.

Applications
This cable is suitable for applications in the field of high-frequency technology, particularly for connecting antennas to receivers, transceivers, or measuring instruments. Typical use cases include radio systems, WLAN systems, satellite receivers, or laboratory environments where reliable signal transmission at frequencies up to the GHz range is required. The 50 Ω impedance matches the standard for many HF systems and ensures minimal reflection and signal distortion.

Features and Specifications in Detail
The RG-174 cable is a flexible, flat coaxial cable with high mechanical durability and low signal attenuation. The cable attenuation is 1.5 dB per meter at a frequency of 1.5 GHz, enabling good signal quality over the full length of 3 meters. The gold-plated contacts ensure long-lasting electrical conductivity and protect against oxidation, extending the cable's service life. The connection technology using BNC and SMB connectors is widely used in HF technology and allows for quick and secure installation.

Technical Explanation
A coaxial cable such as RG-174 consists of a central conductor surrounded by an insulator, which is in turn surrounded by a shield (usually made of metal braid) and an outer protective jacket. This structure minimizes electromagnetic interference and ensures clean signal transmission. The 50 Ω impedance is a standard value used in many HF systems to minimize reflections and signal loss. The attenuation of 1.5 dB per meter at 1.5 GHz indicates how much signal strength is lost over the cable's length — the lower the attenuation, the better the signal transmission. The cable is not designed for use in damp or wet environments, as no specific protection rating (e.g., IP67) is specified.

Compatibility and Accessories
The cable is compatible with devices that use BNC and SMB connectors. It can be used, for example, to connect antennas to radio modules or measuring instruments. In the source Accessories and Alternatives, no specific accessories are mentioned, so no further combination options can be derived from the sources.

Installation and Mounting
Installation is done by simply plugging the BNC and SMB connectors into the corresponding sockets on the devices. The connectors are mechanically stable and provide a secure connection without requiring additional fastening. Due to the flexible cable structure, it can be easily bent and routed in confined spaces. No special mounting equipment or tools are required.

Operational Advantages
The cable provides reliable signal transmission at high frequencies, thanks to its low attenuation and gold-plated contacts. The 3-meter length offers sufficient flexibility for typical applications without significantly degrading signal quality. The use of BNC and SMB connectors enables universal compatibility with many HF devices. The cable construction is robust and suitable for use in technical installations.
