Tetra 380MHz Band Selective 380-385 MHz 390-395 MHZ Two Way Radio UHF Outdoor Signal Repeater Amplifier yokhala ndi RJ45
Gulu lafupipafupi 380-385 MHz (uplink) / 390-395 MHz (downlink) lakonzedwa kuti lithetse mavuto a siginecha yofooka yam'manja, yomwe ndi yotsika mtengo kwambiri kuposa kuwonjezera Base Station yatsopano (BTS).Kugwira ntchito kwakukulu kwa RF Bi-Directional Amplifiers system ndikulandila siginecha yamphamvu yotsika kuchokera ku BTS kudzera pawayilesi yawayilesi ndikutumiza siginecha yokwezeka kumadera omwe kulumikizidwa kwa netiweki sikukwanira.Ndipo siginecha yam'manja imakulitsidwanso ndikutumizidwa ku BTS kudzera mbali ina.
Zowonetsa Zamalonda:
● Ndi kamangidwe ka modularized, yosavuta kukonza
● Kuwunika kwakutali kwa mapulogalamu (seri port), yosavutakusamalira ndi kasamalidwe.
● IP55 yopanda fumbi & yopanda madzi, yokhala ndi zofunikira zochepa pa malo oyika;
● Yokhala ndi amplifier yamphamvu yamphamvu kwambiri komanso duplexer yokana kwambiri, yotha kukana kusinthasintha kwa mawu ndi ma sigino abodza.
