The Faraday Cage Effect of Insulated Metal Garage Doors
In modern villas across Riyadh, Dammam, and Jeddah, heavy double-sided steel insulated garage doors and thick concrete boundary walls create a Faraday Cage effect. These dense metallic structures reflect and attenuate radio frequency signals, preventing wireless remote transmitters from reaching the internal receiver on the motor unit.
How External Coaxial Antenna Extensions Resolve Signal Blockage
- Low-Loss 50Ω / 75Ω RG-58 Coaxial Cabling: Relocates the RF receiving element from the motor logic board to an external outdoor position outside the metal barrier.
- High-Gain Tuned Whip Antenna (433.92 / 868 MHz): Mounted high on the exterior perimeter wall or garage soffit to achieve line-of-sight signal capture from over 80 meters away.
- Weatherproof IP66 Housing: Sealed against intense summer UV rays and desert sand ingress.
