Te nuingaVHFKo nga Whakanui-a-rua he mea whakarite i te Reo Irirangi i hangaia hei hapai i te tono auau motuhake.

- Kingtone JIMTOM®VHFWhakanui-a-rua(BDA) kua hoahoatia hei whakaoti rapanga o te tohu pūkoro ngoikore, he iti ake te utu i te taapiri i te Teihana Paerewa hou (BTS).Ko te mahi matua o te RF VHF Bi-directional-Amplifier(BDA) 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 kapi o te whatunga.Na ka whakanuia ano te tohu pūkoro ka tukuna ki te BTS ma te huarahi rereke.

Nga waahanga matua

◇ Hototahi ki DMR, TETRA, TETRAPOL, P25 (Ph1 me Ph2)

◇ PA ahorangi teitei, Te whiwhinga punaha teitei, Hangarau ALC mohio

；

◇ tātaritanga aunoa, Mahi Aunoa te mahi watea;

◇ Kaiwhakamahi te whakarite mana whiwhi, UL me DL motuhake;

◇ Mana Whakahaere Aunoa;

◇ Aroturuki a-rohe me te mamao (kowhiringa) me te whakaoho hapa aunoa & te mana mamao;

◇ IP67 / NEMA4X hoahoa huarere mo te whakaurunga o nga rangi katoa;
