2m 70cm DualBand Filter 200W Low Loss
Low insertion loss and high power 2m 70cm DualBand Filter 200W transmit/receive. The filter will prevent receiver overload from any HF 6m and 4m station and will suppress all harmonic over 450MHz. Including 720MHz, 864MHz, GSM 930MHz, or 23cm 1296 MHz.
Especially good to put it in line with DualBand 2m-70cm single connector antennas.
Our 2m/70cm dual-band filter is designed to effectively filter out unwanted signals and interference, ensuring a clean and clear signal for your transmissions. It features a bandpass design, which allows signals within the 2m and 70cm bands to pass through while blocking out signals outside of these frequencies. Its compact size and easy installation make it a convenient and practical addition to your radio setup.
