DSC GS-50ANTQ 50ft Quad-Band External Antenna Extension Kit

The DSC GS-50ANTQ is a 50-foot (15.24 m) quad-band external antenna extension kit designed to extend the cellular receive antenna of compatible DSC GSM/GPRS/HSPA alarm communicators to a superior signal location. When a communicator is installed in a basement, metal enclosure, or other RF-attenuated environment, the GS-50ANTQ provides the cable reach necessary to place the antenna at a wall penetration, roofline, or other high-signal point — improving link reliability without relocating the panel. The kit is rated for both interior and exterior mounting, making it equally suited to a discreet interior run or a fully exposed exterior installation. As a genuine DSC accessory engineered alongside the communicator product family, it maintains the system integrity expected in UL-listed life-safety applications and installs via the communicator's threaded antenna connector with no additional hardware required.

Key features & benefits

• 50-Foot (15.24 m) Cable Reach — Provides 15.24 m of low-loss antenna cable, giving installers the flexibility to route from the panel to the optimal RF reception point — whether at a window, exterior wall, or roofline — without compromising panel placement.
• Interior and Exterior Mounting Rated — Officially rated by DSC for both interior and exterior mounting locations, accommodating a wide range of installation environments and eliminating the need for separate indoor-only or outdoor-only antenna accessories.
• Signal-Strength Optimization — Designed specifically to improve cellular signal strength received by the communicator in difficult RF environments such as basements, concrete structures, or steel enclosures where the communicator's onboard whip antenna may yield insufficient signal.
• Direct Communicator Connector Interface — Attaches directly to the threaded antenna connector on compatible DSC communicator panels, replacing the factory whip antenna with no adapters or additional components required.
• Part of a Matched Antenna Extension Family — The GS-50ANTQ is the longest option in DSC's quad-band antenna extension kit family, which also includes the GS-15ANTQ (15 ft, interior-only) and GS-25ANTQ (25 ft, interior/exterior), allowing integrators to select the minimum cable length needed for each job.
• Genuine DSC Life-Safety Accessory — Supplied and supported directly by DSC (Digital Security Controls), ensuring compatibility assurance and traceability within UL-listed alarm system installations.
