The MFJ-1025 is a powerful tool that can turn your antenna system into a directional receiving array. It allows you to place a null up to 60dB deep on any type of noise and interference coming from multiple directions and wave angles. With this device, you can wipe out interference and noise before it even reaches your receiver. It works effectively on all modes - SSB, AM, CW, FM - and covers frequencies from 1.5 to 30 MHz. One push of a button allows you to instantly switch from nulling to peaking a signal, improving weak signal reception. The MFJ-1025 can eliminate various types of noise, including lightning crashes, power line noise, lamp dimmers, electric drills, and more. It can even null out a strong local ham operator who may be overloading your receiver. Additionally, it can help you uncover exotic distant stations hidden beneath local AM broadcast signals. This device is compatible with all modes and frequencies within the MF and HF amateur bands and shortwave broadcasts. It effectively cancels interference without affecting the desired signal, preventing overload in your sensitive receiver. The MFJ-1025 allows you to adjust both the direction and wave angle of null or peak, while the antennas remain physically stationary. It can also be used as an adjustable phasing network, combining two antennas to improve directional patterns and signal levels. The MFJ-1025 offers flexibility and control, allowing you to null or peak signals with ease. It can be connected between your transmitting antenna and transceiver and can be used with either a built-in active antenna or an external one. The device features a near-constant amplitude-phase control and an RF sense T/R switch to bypass your transceiver when transmitting. It also has an adjustable delay time and can be used with an external antenna to null or peak signals.
