ʻO Tetra 380MHz Band koho 380-385 MHZ 390-395 MHZ ʻElua ala ʻelua Radio UHF Outdoor hōʻailona Repeater Amplifier me RJ45
Hoʻolālā ʻia ka alapine alapine 380-385 MHz (uplink)/390-395 MHz (downlink) e hoʻoponopono i nā pilikia o ka hōʻailona kelepona nāwaliwali, ʻoi aku ka maikaʻi ma mua o ka hoʻohui ʻana i kahi Base Station (BTS) hou.ʻO ka hana nui o ka ʻōnaehana RF Bi-Directional Amplifier ka loaʻa ʻana o ka hōʻailona haʻahaʻa haʻahaʻa mai BTS ma o ka hoʻouna ʻana i ka lekiō a laila hoʻouna i ka hōʻailona hoʻonui ʻia i nā wahi i lawa ʻole ai ka uhi pūnaewele.A hoʻonui ʻia ka hōʻailona kelepona a hoʻouna ʻia i ka BTS ma o ka ʻaoʻao ʻē aʻe.
Nā Manaʻo Huahana:
● Me ka hoʻolālā modularized, maʻalahi no ka mālama
● lako polokalamu mamao ka nānā 'ana (serial port), oluolu nomālama a mālama.
● IP55 dustproof & wai, me nā koi haʻahaʻa ma ka hoʻonohonoho ʻana;
● Me ka mana amplifier kiʻekiʻe-linearity a me ka duplexer kiʻekiʻe-rejection, hiki ke hōʻole i ka intermodulation a me nā hōʻailona hoʻopunipuni
