MFJ-1025 – 1.5-30 MHz Noise Canceller


MFJ-1025 Noise Canceller (alternative to the MFJ-1026) without the built-in Active Antenna. Plug your station antenna into the MFJ-1025 and your antenna system turns into a directional receiving array!


Place a null up to 60dB deep on any type of noise. Plug your station antenna into the MFJ-1026 and your antenna system turns into a directional receiving array!  You can place a null up to 60dB deep on any type of noise and interference arriving from any single direction and wave angle.

It works on all modes. SSB, AM, CW, FM and frequencies from 1.5 to 30 MHz. You can instantly change from nulling to peaking a signal at a push of a button and improve weak signal reception!

Wipe out all types of Noise. Lightning crashes from distant thunderstorms, severe power line noise from arcing transformers and insulators, lamp dimmers, touch-controlled lamps, electric drills, motors, industry processes, and TV birdies.

Can’t copy your QSO? Cast a deep null on him and literally take him out – you won’t even know he’s there. You can dig out a weak station hidden under a powerful one on the same frequency!

Null out your local AM broadcast station. Underneath, you might find an exotic distant station on an island you’ve never heard of.

Works on SSB, AM, CW, FM, RTTY, SSTV, Packet and Pactor. All modes.
It works on all frequencies from 1.5 to 30 MHz, including all MF and HF amateur bands and shortwave broadcasts.
Interference is much stronger than the desired signal. Can be completely removed without affecting the desired signal.  Prevent overload by cancelling noise before it gets into your sensitive receiver.

Signals can be peaked or nulled.  The MFJ-1025 and your antenna can electrically “rotate the array” while the antennas remain physically stationary adjust both direction and wave angle of null or peak change from nulling to peaking with the push of a button ignore mutual coupling effects as phase and level are adjusted.

Use the MFJ-1026 as an adjustable phasing network. You can combine two antennas to give you various directional patterns and improve receiving signal levels. For example, two verticals become steerable array your beverage and your transmitting antenna can enhance weak signals two parallel staggered Beverage antennas can improve front-to-back ratio or steer nulls.

Connects between transmitting antenna and transceiver. To null, adjust the amplitude and phase controls for minimum S-Meter reading or lowest noise. To Peak, push the reverse button. use a built-in active antenna or an external one. Has near constant amplitude phase control.

RF sense T/R switch bypasses your transceiver when you transmit. Adjustable delay time.  Use an external antenna to null or peak signals.
