Televes K20-12 Compact Headend 12 transpondér DVB-S2 na QAM

Distributing satellite TV over a coaxial cable network usually requires a rack full of receivers and modulators, consuming space, power, and budget. The Televes K20-12 Compact Headend solves this by integrating 12 DVB-S2 satellite tuners and 12 QAM modulators into a single 1U-high unit. It receives up to 12 satellite transponders, processes them, and re-modulates them into a DVB-C (QAM) signal for distribution over existing coaxial infrastructure. This professional headend is ideal for hotels, hospitals, campuses, and multi-dwelling units that need centralized satellite TV distribution without a separate receiver for every television.

Who is it for

System integrators, installers, and property managers who need to distribute satellite channels over an existing cable TV infrastructure will find the K20-12 indispensable. It is perfect for hospitality environments, apartment buildings, office complexes, and any facility requiring centralized TV distribution. The K20-12 replaces multiple consumer satellite receivers and simplifies the distribution of both pay-TV and free-to-air channels.
