75 Ohm 22 kHz Block
 
Introduction

This 22 kHz Block is designed for use in SMATV/ VSAT systems to block the 22 kHz tone burst and DiSEqC signals.

This disables the satellite band select function but does not influence the received signal.

It can be easily installed at any point between satellite receiver and dish antenna.
