The present invention provides a HF / VHF band ultra-wideband electromagnetic pulse protection module, characterized in that: it comprises a coaxial cavity low-pass filter, the gas discharge tube, high-power and low-power TVS TVS tube tube, coaxial cavity TVS and power between the gas discharge...
The HF band is defined as the frequency range of 3 to 30 MHz. In practice, most HF radios use the spectrum from 1.6 to 30 MHz. Most long haul communications in this band take place between 4 and 18 MHz. Higher frequencies (18 to 30 MHz) may also be available from time to time, ...
求翻译:HF (high-frequency): Signals in the range of 3 to 30 MHz. In amateur radio, HF is also shorthand for 160-10 meters (1.8 to 29.7 MHz), or the “HF bands.” 160 meters actually falls in the MF range (0.3 to 3 MHz). The 6- meter band (50-54 MHz) is often included ...
