The Retekess F4408A is a high-performance wireless RF signal repeater designed to extend the coverage range and improve signal reliability of paging and service calling button systems in restaurants, cafes, hotels, clinics, and warehouses.
Operating at 433.92 MHz (with 315 MHz support), the repeater receives weak signals from distant transmitters or call buttons and re-transmits them with a powerful 500mW output power. This easily overcomes physical obstacles like thick walls and metal structures, preventing missed call signals between buttons and receiver units or wrist pagers.
Key Features
- Range Extension: Drastically amplifies call button signals up to 500-1500 meters in open area settings.
- Broad Compatibility: Works seamlessly with Retekess call buttons (e.g., T117, TD019) and standard 433.92MHz transmitters.
- Multi-Transmitter Support: Capable of learning and repeating signals from up to 100 individual transmitters.
- Easy DIP Switch Configuration: Built-in switches allow straightforward mode selection and learning options.
- Continuous DC Power Supply: Powered via a 12V DC power adapter for non-stop operational stability.
