MFJ-1025 Noise Canceller is a powerful tool for reducing or eliminating unwanted noise and interference from your HF and VHF signals.

Using MFJ’s advanced dual-antenna noise cancelling and phasing system, the MFJ-1025 allows you to dramatically reduce man-made noise sources, such as power line buzz, computer noise, plasma TVs, and local RFI, without sacrificing signal quality.

By combining signals from your main antenna and a separate noise sensing antenna, the MFJ-1025 cancels out noise through precise phase and amplitude adjustments, leaving your desired signal clear and strong.

Ideal for urban and suburban radio operators, this noise canceller is compatible with HF transceivers and receivers from all major brands (Yaesu, Icom, Kenwood, Elecraft, etc.), covering 1.5 to 30 MHz and VLF reception.
