Ko te hanganga taketake o te hononga RF coaxial kei roto ko te kaikawe pokapū (he pai, he kino ranei te whakapiri ki te pokapū), te rauemi dielectric i waho o te kaitarai o roto (mea whakamaarama) me te whakapiri o waho rawa atu (te mahi whakamarumaru, ara, te huānga papa o te ara iahiko).Ko te hononga RF coaxial me te huihuinga taura whakawhiti coaxial i roto i te waea atamai ki te takaro i te momo tauranga RF kōwae me te papahoahoa i waenga i te mahi o te tuku tohu RF, i tua atu, ka taea hoki te whakamahi hononga RF ki te pakaru i te ara iahiko RF, na reira ka arahi ki te te tohu RF o te waeine i raro i te whakamatautau, ki te whakatutuki i te whakamatautau o te RF circuit.
