Stronger gain, more efficient, and counter-interference. Equipped with a high-performance antenna, the 2.4G antenna is increased from PLDB's 8 DBi to gain up to 13 DBi, 5.8G antenna gain up to 16 DBi, VSWR ≤ 1.4, and efficiency is close to 80%. 2.4G antenna ± 45 ° polarization, 5.8G antenna horizontal and vertical polarization, effectively avoid the interference of the dual antenna.
