14/18V rackmounted satellite multiswitch. 5 input simple interface design provides 4 satellite polarity inputs plus 1 off air antenna and 16 outputs for quick installation. Available in 40 to 2150MHz wide frequency range. Compatible with DIRECTV phase III and other reception systems that utilize 22kHz tone switching. PIN diode matrix reduces polarity transfer time and digital artifacts, providing consistent picture quality. 14 or 18V DC and 22kHz tone are provided to power the LNB and conduct internal switching. Built-in amplifier compensates for insertion losses, reducing need of external amplification. Heavy-duty high efficiency internal power supply eliminates excessive current draw requirements on receivers.
