I-Tetra 380MHz Ibhendi Ekhethiwe 380-385 MHZ 390-395 MHZ Two Way Radio UHF Outdoor Signal Repeater Amplifier ene-RJ45
Ibhendi yefrikhwensi engu-380-385 MHz (uplink)/390-395 MHz (downlink) iklanyelwe ukuxazulula izinkinga zesignali yeselula ebuthakathaka, eshibhe kakhulu kunokwengeza i-Base Station entsha (BTS).Ukusebenza okuyinhloko kwe-RF Bi-Directional Amplifiers uhlelo ukuthola isignali yamandla aphansi evela ku-BTS ngokudluliswa kwamafrikhwensi omsakazo bese idlulisela isignali ekhulisiwe ezindaweni lapho ukutholakala kwenethiwekhi kungenele.Futhi isignali yeselula nayo iyakhuliswa futhi idluliselwe ku-BTS ngendlela ehlukile.
Izithombe ezinhle kakhulu zomkhiqizo:
● Ngedizayini ene-modularized, kulula ukuyilungisa
● Ukuqapha okukude kwesofthiwe (imbobo ye-serial), kulula ngakhoukugcinwa nokuphatha.
● I-IP55 ingangenisi uthuli futhi ingangeni manzi, enezidingo eziphansi endaweni yokufaka;
● Nge-high-linearity power amplifier kanye ne-high-rejection duplexer, ekwazi ukwenqaba ukuguquguquka kanye namasignali angamanga.
