All DTC receivers operating at frequencies above 850MHz require downconverters. DTC downconverters offer excellent low noise performance and are gain selectable, which dictates how much cable they can drive (typically 10-15m for the low gain and 50-100m for high gain; for precise cable run length calculations contact DTC). Power is drawn from the connected receiver.

DTC downconverters are connected directly under the antenna and are designed for permanent outdoor deployment with magnetic, cable-tie and screw-hole fixings for maximum flexibility.

Available in three variants;
- DCBGS (Surveillance) TNC to TNC
- DCBGSB (Broadcast) N-Type to BNC
- DCEBGSB (Broadcast, Extended Barrel) N-Type to BNC.
