Description
Dual linear polarization log Periodic antenna DS-SJ-20400C, operating from 0.2 to 4GHz with a nominal 7dB gain and low VSWR 2.5:1 with N Type Female output connector. The model DS-SJ-20400C has a high front-to-back ratio, and high power gain through at all frequency in the band. It can handle full 300W continuously and 3000W peak power. Constructed of lightweight corrosion-resistant aluminum, the antenna will provide years of trouble-free indoor and outdoor service. This log Periodic antenna has dual linear polarization, ideally suited for gain reference, antenna measurement, reflector feed, chamber evaluation, far-field measurement, system intergration and other applications. Standard tripod will be provided according to customers' requirement, the joint is universal.
