The Zetagi F27 TVI CB Harmonic Noise Filter is an essential accessory for anyone seeking clear, uninterrupted CB radio communication. Acting as a low-pass filter, it is specifically engineered to reduce harmonic signals above 30 MHz, ensuring clean signal transmission and interference-free radio use.
This filter is especially useful in environments where radio transmissions may interfere with televisions or other electronic devices. It prevents unwanted harmonics from reaching sensitive equipment, while allowing your 27 MHz radio signals to pass through unaffected—making it ideal for high-power radio setups where harmonics can be a problem.
Technical highlights include a working frequency range of 0–30 MHz and a maximum output power of up to 300 watts, supporting even high-powered CB radios. With an impressively low insertion loss of just 0.25 dB, you enjoy minimal signal loss and superior communication quality.
Its compact design (110 x 33 x 50 mm) makes it easy to integrate into any radio setup without taking up much space. The standard 50 Ohm impedance ensures perfect compatibility with most CB radios and antenna systems. Both input and output feature UHF (PL) connectors for simple, fast, and standard installation—no extra adapters needed.
This low-pass filter not only preserves radio signal clarity but also protects nearby equipment from unwanted interference. It's especially beneficial in densely populated areas, where radio transmissions might disrupt televisions or other sensitive devices. If clean signals and interference-free operation are priorities, this noise filter is a must-have—compact, powerful, and designed for reliable, hassle-free communication. Choose it for maximum performance and purity in your CB radio experience.
