I hangaia te punaha Whakanui-a-Kingtone Bi-Directional Amplifier ki te whakaoti rapanga o te tohu waea ngoikore, he iti ake te utu atu i te taapiri i te Teihana Turanga (BTS) hou.Ko te mahi matua o te punaha RF Bi-Directional Amplifiers 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.
◇ PA raina teitei;Te whiwhinga punaha teitei ；
◇ Hangarau ALC mohio;
◇ Hangarau AGC mohio;
；
◇ Mahi Aunoa te mahi watea;
◇ Hangarau whakauru me te mahi pono;
◇ Aroturuki a-rohe me te mamao (kowhiringa) me te whakaoho hapa aunoa & te mana mamao;
◇ Te hoahoa huarere mo te whakaurunga o nga rangi katoa;
