HF Balun with Diversity Reception Output

The HamTEK BLN-DRX-0001 HF Choke with DRX (Diversity RX) is the first balun designed to use what others throw away. It’s a choke balun that suppresses unwanted common-mode currents on your antenna feedline and simultaneously extracts that same signal as a protected, low-level output for noise-cancelling or diversity reception systems. Connect the DRX output to a noise canceller or diversity input and your main antenna becomes its own noise probe. No need for a secondary antenna system. Built and tested in the UK, the BLN-DRX-0001 combines robust construction with true
RF innovation — turning common mode signals into an asset for cleaner, quieter reception.
