## Long description

The Kathrein ESU 53 Grey Metal is a programmable single-cable outlet designed for interference-free reception in single-cable satellite systems. The outlet contains a micro-controller that monitors signalling within single-cable installations and enforces user ID checks so that only enabled user bands are transmitted from the end device to the multi-switch. Configuration is performed using the free "Kathrein ESU" app together with the SWP 50 programming device, ensuring controlled access to satellite signals and stable operation across multiple residences.
Advantages
The ESU 53 provides programmable user-band control to prevent signal interference in shared single-cable systems. Built from grey metal, it offers durable construction for long-term reliability. The integrated micro-controller enforces user ID checks and protects other outlets from misconfigured or incompatible end devices. Configuration can be protected with a PIN to prevent unauthorised changes.
Suitable for
Single-cable satellite installations in apartments or multi-dwelling units
Systems requiring user-band restriction to avoid cross-residence interference
Installations where durable, metal-shelled outlets are preferred
