## Long description

The Kathrein VWS 04 is a compact TV signal amplifier designed to improve reception quality for satellite intermediate frequency (Sat-IF) and terrestrial signals. With F-type connectors and compact dimensions (74 x 46 x 21 mm), it is intended for indoor mounting and for use where signals are distributed to multiple receivers. The unit complies with applicable safety and EMC directives.
Advantages
The amplifier provides gain for the Sat-IF band (950–2500 MHz) while offering a passive bypass for the terrestrial range (5–862 MHz). It supports remote powering over the RF output and includes a DC bypass for LNB remote feeding. Its small size and F connectors make it simple to integrate into existing installations to reduce signal loss when splitting signals between several receivers.
Suitable for
 Enhancing Sat-IF signals (950–2500 MHz) in multi-receiver installations
 Indoor installations where a small-form amplifier is required
 Setups requiring remote feeding of an LNB via the RF line
 Distributing satellite signals to several receivers with reduced loss
