Tikanga mahi otaura coaxial
Ko tetaura coaxialkua wehea kia wha nga paparanga mai i roto ki waho: te waea parahi pokapū (he whenu kotahi o te waea totoka, te waea taupae maha ranei), te insulator kirihou, te paparanga mesh me te kiri waea.Ko te waea parahi o waenganui me te paparanga kawe kupenga ka hanga i te kohanga o naianei.I whakaingoatia na te hononga coaxial i waenga i te waea parahi pokapū me te paparanga kawe whatunga.
Nga taura coaxialwhakahaere i te au tauutuutu kaua i te au tika, ko te tikanga he maha nga wa ka huri te ahunga o te ia mo ia hekona.
Mena ka whakamahia he waea auau ki te tuku i te naianei teitei, ka mahi te waea hei antenna e tuku ana i te reo irirangi ki waho, ka pau te kaha o te tohu ka whakaitihia te kaha o te tohu kua riro mai.
Tauira coaxialkua hoahoatia hei whakaoti i tenei raru.Ko te reo irirangi ka puta mai i te waea o waenganui ka wehea e te paparanga kawe mata, ka taea te whakatuu whenua hei whakahaere i te reo irirangi kua tukuna.
Tauira coaxialhe raru ano hoki, ara, mena he ahua nui te tangohanga o tetahi waahanga o te taura, he rerekee ranei, katahi ka kore e rite te tawhiti i waenga i te waea o waenganui me te paparanga kawe mata, na reira ka hoki mai nga ngaru reo irirangi o roto ki te puna tohu.Ko tenei paanga ka whakaiti i te mana tohu ka taea te whiwhi.Hei whakatau i tenei raru, ka taapirihia he paparanga kiriweti kirihou i waenga i te waea o waenganui me te paparanga arataki mata kia pai ai te tawhiti i waenga i a raatau.Ma tenei ano ka maro te taura kia kore e ngawari te piko.
Ko te rauemi whakamarumaru otaura coaxialkua tino pai ake i runga i te kaikawe o waho, mai i te kaikawe o waho tubular tuatahi, ka huri hei whakarewa kotahi, he whakarewa takirua.Ahakoa he pai rawa te mahi whakangungu a te kaitakawaenga o waho, ehara i te mea ngawari ki te whakapiko me te kore e watea ki te whakamahi.Ko te kaha o te whakamarumaru o te whiri papa-kotahi te mea kino rawa atu, a ko te impedance whakawhiti o te whiri papa-rua he 3 nga wa iti iho i tera o te whiri papa-kotahi, no reira ka tino pai ake te whakamarumaru o te whiri papa-rua i tera o te kotahi- whiri paparanga.Ko nga kaihanga taura coaxial nui kei te whakapai tonu i te hanganga o waho o te taura hei pupuri i tana mahi.
