DCW2004B VHF Sequencer

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.
