The MFJ-1025 is effective with all types of interference on all modes. Signals can be peaked or nulled. Â 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 ...

The MFJ-1025 is designed to cancel noise or interference, or boost signal-to-noise ratio, before the noise affects sensitive receiver circuits. Unlike conventional noise blankers, the MFJ-1025 can be effective on all types of noise, including unwanted signals. The MFJ-1025 provides user adjustment of phase and amplitude of two antenna inputs.

Follow the MFJ recommendations regarding the antennas in order to obtain the best results. The changes made were shown to be improved both by our instruments and by ear.

The MFJ-1025/1026 contains BCB filters that roll off at about 1.9MHz. To extend operation lower in frequency: Remove L3, L4, L5, L6. Short C8 and 16. Increase the value of C12 and 13 by the same factor as the decrease in frequency. For half the frequency, double C12 and 13.

It contains an auxiliary preamp, and an internal whip antenna that can be used as a noise antenna. In receive mode, the MFJ-1025 takes the input from two antennas, main and auxiliary. At each antenna input there is a high pass lter with 5.6 H …

2013年6月17日 · 使用“mfj-1026相位衰减/放大器”的时候，可以调高参考天线（参考天线有rf放大开关），衰减主天线的信号（一般不谐振的天线收噪声多一些），这样也就改善了选择性。

MFJ 1025 is a versatile noise and interference canceler that can enhance your reception experience. It allows you to combine or subtract signals from two antennas, effectively reducing unwanted noise or boosting weak signals. With adjustable phase and amplitude controls, you can fine-tune the signal to your liking.
