Explanation:
Detailed explanation-1: -A Yagi–Uda antenna, or simply Yagi antenna, is a directional antenna consisting of two or more parallel resonant antenna elements in an end-fire array; these elements are most often metal rods acting as half-wave dipoles .
Detailed explanation-2: -Omni antennas can pick up cellular signals from any direction, but Yagi antennas usually need to be pointed directly at a cellular tower for the best performance.
Detailed explanation-3: -A Yagi antenna is one of two outdoor antennas you can purchase to improve your cellular signal. This antenna aims its power in a single direction to zero in on a particular network carrier which often allows it to get more gain-a stronger signal-than Omni-directional antennas.
