DiSEqC / 22KHz Block
 
 
    Features
 
* CE Approved

* Round Model, Easy Installation

* Low Insertion Loss

* Excellent Return Loss

* Low Voltage Drop Down

* Suitable for SMATV systems
 
Introduction

This 22 KHz Block is designed for use in SMATV systems to block the 22KHz 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).
