The universal single feed system UAS 571 is suitable for the reception of satellites in Ku-band, such as Astra, Eutelsat, or TürkSat. Switching between the frequency bands (low/high) and the polarizations (horizontal/vertical) is done by selecting the program on the receiver. The feeding system complies with the Astra specification for universal feeding systems. It is suitable for single systems with two polarizations and two frequency ranges (2 x low/high band) and for linear polarization. There is an independent choice of horizontal/vertical and low/high band from any receiver. Switching between horizontal/vertical and low/high band is done via the coaxial cable using 14/18 V and 22 kHz. Power is supplied via a low voltage cable. The UAS 571 is suitable for multifeed due to its compact design (CAS 60/80/90/120). The LNB and cable connections are completely protected in a vented housing with a protection class of IP 54.
