DCS high-frequency signals are short-wave signals, which require high equipment conditions and process a large amount of information. Therefore, high frequency signals are relatively difficult to amplify. Generally, the power of Cheap Hand Held Cell Phone Blocker is lower than that of high frequency. The higher the frequency, the greater the impedance, so it is more difficult to amplify, but the high frequency signal has a clear voice and high stability.
