The MFJ-1025 and your antenna system turn into a directional receiving array, You can place a null up to 60dB deep on any type of noise and interference arriving from many single directions and wave angles. Wipeout interference and noise before it gets into your receiver! 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 Wipe out ... lightning crashes from distant thunderstorms, severe power line noise from arcing transformers and insulators, lamp dimmers, touch-controlled lamps, electric drills, motors, industry process, TV birdies...Strong local ham overloading your sensitive receiver? 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.
A noise blanker cant...Interference is much strong than the desired signal can be completely removed without affecting the desired signal.
Prevent overload by canceling noise before it gets into your sensitive receiver.
The MFJ-1025 is effective with all types of interference on all modes.

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. Examples... two verticals become steerable array... your beverage and your transmitting antenna can enhance weak signals...two parallel staggered. Beverage antennas can improve the 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.
