Repeater (ZKR-1)

Repeater is a cost effective solution for making up the coverage blind area and expanding the coverage scope. Radio frequency signal can be received and transmitted, uplink and downlink signal both can be ampliformed. It is effective to expand coverage range and make up the blind area, restrain the interferefering signal, improve communication quality and expand the coverage scope. The output power of the Repeater is 25W, 20W, 10W, 5W, 2W, 1W and 0.5W etc.
