Uhf Radio Repeater 400MHz Bi-Directional Amplifier (BDA) Tetra UHF Channel Selective Signal Repeater Booster pūnaha i hangaia hei whakaoti rapanga o te tohu waea ngoikore, he iti ake te utu i te taapiri i te Teihana Turanga (BTS) hou.Ko te mahi matua o te punaha RF Repeaters ko te whiwhi tohu iti-hiko mai i te BTS ma te tuku auau reo irirangi katahi ka tuku i te tohu whakakaha ki nga waahi kaore i te tika te kapinga whatunga.Na ka whakanuia ano te tohu pūkoro ka tukuna ki te BTS ma te huarahi rereke.
Nga waahanga matua
◇ Hototahi ki TETRA, TETRAPOL, P25 (Ph1 me Ph2)
◇ PA ahorangi teitei, Te whiwhinga punaha teitei, Hangarau ALC mohio
；
◇ tātaritanga aunoa, Mahi Aunoa te mahi watea;
◇ Ka taea e te kaiwhakamahi te whakahaere mana whiwhi, UL me DL motuhake, mo ia hongere;
◇ Aroturuki rohe me te mamao (he kowhiringa) me te whakaoho hapa aunoa & te mana mamao;Kawa SNMP (kwhiria) .
◇ IP67/NEMA4X Te hoahoa huarere mo te whakaurunga o nga rangi katoa.
