Tetra 400 MHz Two Way Radio UHF Channel Selective RF BDA Signal Repeater Bi-Directional Amplifier ke RF signal booster e sebelisetsoang ho ntlafatsa puisano ea seea-le-moea maemong ao lets'oao la seea-le-moea.
BDA (Bi-Directional Amplifier) e sebelisetsoa ho fana ka puisano ea mahlakore a mabeli pakeng tsa liteishene tsa seea-le-moea le setsi sa motheo e le hore li lekane tikolohong ea mofuta ofe kapa ofe.E ka sebelisoa ka ntle ho atolosa sebaka sa tšireletso ea setsi sa setsi, ho etsa hore litšebeletso tsa puisano li fumanehe libakeng tse se nang matšoao kapa tse fokolang, tse amoheloang haholo bakeng sa lithanele, litsela, literene, libaka tse ka thōko, libaka tsa bolulo tse phetheselang, joalo-joalo.
Likarolo tse ka Sehloohong
◇ E lumellana le TETRA, TETRAPOL, P25 (Ph1 le Ph2)
◇ High linearity PA, High tsamaiso phaello, Intelligent ALC theknoloji
◇ Duplex e felletseng le ho itšehla thajana ho tloha holimo ho ea ho downlink;
◇ Tlhahlobo ea Auto, Opereishene ea Othomathike e bonolo;
◇ Taolo e feto-fetohang ea mosebelisi, UL le DL e ikemetseng, mocha ka mong;
◇ Tlhokomelo ea lehae le e hole (ka boikhethelo) e nang le alamo ea phoso ea othomathiki &taolo ea remoutu; protocol ea SNMP (ka boikhethelo).
◇ Moralo oa IP67/NEMA4X o thibelang boemo ba leholimo bakeng sa ho kenya maemo a leholimo kaofela.
