描述

The YS4306 is a 6-element directional Yagi antenna designed for UHF communications in the 430–450 MHz frequency range. It delivers a nominal gain of 12.2 dBi with a front-to-back ratio of 20 dB and supports both vertical and horizontal polarization, offering horizontal and vertical beamwidths of 58° and 67° respectively. The antenna is constructed from high-strength 6061-T6 aluminum and is rated for 300 W maximum power with a VSWR of less than 2:1 and return loss of -10 dB maximum, featuring an N-female connector termination and fixed tuning. It is engineered to withstand harsh environmental conditions including wind velocities up to 150 mph and is suitable for both transmitting and receiving applications in fixed-installation scenarios such as base stations, repeaters, and point-to-point communications systems.
