## Long description

The ESU 57 Grey Metal Kathrein programmable single-cable outlet ensures interference-free reception in single-cable satellite systems. Housed in a robust grey metal enclosure, the outlet integrates a micro-controller that monitors signalling within the single-cable installation and enforces user ID checks so that only enabled user bands are transmitted from the end device to the multiswitch.
Advantages
Programmability via the dedicated Kathrein ESU app and the SWP 50 programming device allows precise control of enabled user bands. The metal housing provides durable protection for the electronics and supports long-term installation. Intelligent monitoring prevents a misconfigured or incompatible end device from affecting other programmable outlets, maintaining stable, interference-free operation across multiple residences.
Suitable for
 Single-cable satellite installations in multi-dwelling units
 Installations requiring per-outlet user-band control and security
 Professional and residential projects where durable metal housing is required
