  • Does the longer the antenna length Dec,29 2020
    Does the longer the antenna length, the better the signal it receives? Don't take it for granted, because the theory and practice prove that this statement is unscientific, and the optimal length of the antenna is actually one fourth of the wavelength. The length of the antenna is determined by the frequency of the transmitted and received signals, that is, the wavelength. When the length of the a...
