A 6 dBi LPDA (Log-Periodic Dipole Array) antenna is a directional antenna designed for wideband applications, offering a gain of 6 decibels isotropic (6 dBi) across a specific frequency range. Typically, these antennas cover a range from 700 MHz to 3500 MHz, encompassing various cellular bands like GSM, 3G, 4G/LTE, and even some 5G frequencies. They are characterized by their directional radiation pattern, meaning they focus the signal in a specific direction, and are commonly used for applications like cellular signal boosting, network extension, and base station setups.
