3 Graders monoblock til 4 brugere
Beskrivelse:
This Monoblock LNB was designed for the reception of up to 4 satellites and the independent distribution of their signal to up to 4 single tuner STBs (or 2 in case double-tuner STBs are used). It can be used for satellite broadcast reception of any two satellites spaced with 3° degrees on an 80cm dish antenna. It is optimized for High Definition transmissions, provides excellent Noise Figure performance and manufactured to the highest industry quality
standards.
