DCW2004B VHF Sequencer

The DCW 2004 B VHF Sequence-Controller provides precise sequential controlled switching of a VHF power amplifier, rig, transverter and LNA/pre-amplifier and also provides a remote feeding voltage for the Super-Amp range of pre-amplifiers via the coaxial cable.
Covers 6m-70cm

The supply of voltage to masthead preamplifiers via the coaxial cable means easy installation without any need for additional supply lines.
The DCW 2004 B offers three different switching outputs for the precisely delayed switching of power amplifiers, transverters and other devices.
This Sequence Controller removes the risk of damage to preamplifiers by removing the risk of RF spikes from the amplifier feeding into the device.

Suitable for use on 6m through to 70cm.
