Tetra 380MHz Band Selective 380-385 MHz 390-395 MHZ Two Way Radio UHF Kunze Chiratidzo Repeater Amplifier ine RJ45
Iyo frequency bhendi 380-385 MHz (uplink)/390-395 MHz (downlink) yakagadzirirwa kugadzirisa matambudziko eiyo isina simba nharembozha, iyo yakachipa zvakanyanya pane kuwedzera Base Station (BTS).Kushanda kukuru kweRF Bi-Directional Amplifiers system ndeyekugamuchira yakaderera-simba chiratidzo kubva kuBTS kuburikidza neredhiyo frequency kutapurirana uye wobva waendesa chiratidzo chakasimudzirwa kunzvimbo dzisina kuvharwa netiweki.Uye iyo nharembozha inokwidziridzwa uye kuendeswa kuBTS kuburikidza neyakapesana.
Zvinonyanya kukosha:
● Ne modularized design, nyore kugadzirisa
● Software remote monitoring (serial port), nyorekuchengetedza uye kutarisira.
● IP55 isina guruva & isina mvura, ine zvinodiwa zvakaderera pane yekuisa nharaunda;
● Iine high-linearity simba amplifier uye high-rejection duplexer, inokwanisa kuramba intermodulation uye zviratidzo zvenhema.
