4-in-1 Filter - Four-in-One Filter, LC Filter, Passive Filter
- This product includes four independent bandpass filters. The filters are divided into 4 frequency bands. The P1 filter ranges from 0.5 to 1.5 MHz, which is suitable for medium-wave radio listening. The P2 filter ranges from 4.5 to 12 MHz, which is suitable for the low-frequency band of short-wave and the 40-meter amateur band. The P3 filter ranges from 12 to 30 MHz, which is suitable for the high-frequency band of short-wave and the 20-meter, 15-meter, and 10-meter amateur bands. The P4 filter is the FM broadcasting frequency, ranging from 88 to 108 MHz. The four-in-one filter can be used in combination with the one-to-four active distributor, providing a pre-filtering function for SDR, radios, and receivers.
- Malachite, pre-filter, compensates for the lack of a pre-filter design in the all-metal aluminum shell Malachite radio. It reduces interference in the medium-wave, short-wave, and FM broadcast frequency bands. The filter is divided into four groups: 0.5 - 1.5 MHz, 4.5 - 12 MHz, 12 - 30 MHz, and 80 - 110 MHz. It can be used in conjunction with a 1/4 distribution unit to achieve simultaneous reception of multiple channels and multiple frequency bands.
