ʻO Tetra 400 MHz Two Way Radio UHF Channel Selective RF BDA Signal Repeater Bi-Directional Amplifier he mea hoʻoikaika hōʻailona RF i hoʻohana ʻia no ka hoʻomaikaʻi ʻana i nā kamaʻilio lekiō i nā kūlana i hōʻailona ai ka lekiō.
Hoʻohana ʻia ʻo BDA (Bi-Directional Amplifier) e hāʻawi i ke kamaʻilio bidirectional ma waena o nā pahu lekiō a me ke kahua kahua i mea e kūpono ai i nā ʻano kaiapuni.Hiki ke hoʻohana ʻia ma waho e hoʻonui i ka laulā o ka base station, e hoʻolako i nā lawelawe kamaʻilio ma nā wahi me nā hōʻailona ʻole a nāwaliwali paha, i hāpai nui ʻia no nā tunnels, nā alanui, nā alahao, nā wahi o waho, nā wahi noho congested, etc.
Nā hiʻohiʻona nui
◇ He kūpono me TETRA, TETRAPOL, P25 (Ph1 a me Ph2)
◇ PA linearity kiʻekiʻe, loaʻa ʻōnaehana kiʻekiʻe, ʻenehana ALC akamai
◇ Duplex piha a me kahi kaʻawale kiʻekiʻe mai ka uplink a i lalo;
◇ ʻO ka diagnostic auto, hana maʻalahi ka hana;
◇ Mea hoʻohana adjustable gain control, UL a me DL kūʻokoʻa, no kēlā me kēia kaha;
◇ Ka nānā 'āina a me ka mamao (koho) me ka 'akomi hewa 'alarm & remote control; SNMP protocol (koho) .
◇ IP67/NEMA4X Hoʻolālā ʻo Weatherproof no ka hoʻokomo ʻana i nā wā āpau.
