## Summary description

Ropam AT-GSM-EXT20 is a 20-meter coaxial extension cable designed for GSM antennas. It provides a reliable RF link between a GSM antenna and equipment, preserving signal integrity over distance. Suitable for extending antenna placement on buildings, masts, or inside enclosures; commonly used in alarm systems, routers, and cellular signal boosters where antenna relocation is required.

## Long description

Ropam AT-GSM-EXT20 is a 20-meter coaxial antenna extension cable designed to connect GSM antennas to equipment while maintaining RF signal integrity over extended distances. The cable enables flexible antenna placement on buildings, masts, or inside enclosures, allowing devices such as alarm panels, routers, and cellular boosters to be positioned separately from the antenna for improved reception or installation convenience.
Advantages
The extension cable offers low-loss RF transmission suitable for GSM frequency ranges, a rugged outer sheath for outdoor or indoor routing, and standard connector compatibility for straightforward installation. Its 20 m length reduces the need for relocating equipment close to the antenna and supports stable cellular links by minimizing reflections and impedance mismatch when properly terminated.
Suitable for
Extending GSM antenna placement on buildings and rooftops
Connecting external antennas to alarm systems and security panels
Linking antennas to cellular routers and mobile broadband devices
Integrating with signal boosters and repeaters where antenna relocation is needed
Routing antenna connections through masts, enclosures, or conduits
Key specifications
Cable type: coaxial extension for GSM antennas
Length: 20 m
Designed frequency range: GSM cellular bands
Construction: center conductor, dielectric, shield, and protective outer jacket
Environmental suitability: indoor and outdoor routing when protected from extreme exposure
Connector compatibility: standard GSM antenna connectors (verify device connector type before installation)
How to use
Route the cable between the antenna and the equipment, avoiding sharp bends and kinks to preserve signal quality. Secure the cable along its run using clips or ties, and protect outdoor sections from prolonged direct sunlight or water ingress at connections. Connect matching connectors at both ends, ensuring tight, yet not over-tightened, coupling to prevent mechanical damage. After installation, check signal levels and adjust antenna position if necessary to achieve the desired reception.
Usage recommendations
For best performance, keep cable runs as short as practical and use proper grounding and surge protection where required. Verify connector types and, if needed, use appropriate adapters rather than forcing mismatched fittings. Inspect connections periodically and replace the cable if outer jacket or shielding is damaged.
