Ko te antenna porowhita-rakau he antenna koki matarohia ko nga rohe o te ringa whakarewa e whakatauhia ana e nga pihinga torino takakau. Ahakoa he rite tonu te ahua ki te porowhita Archimedean, na tana hanganga pangarau ahurei ka waiho hei "antenna motuhake-auau" pono.

Ko tana mahi e whakawhirinaki ana ki tana hanganga taapiri-whaiaro (he rite te ahua o te whakarewa me te hau) me tona ahua koki noa. Ko te rohe kaha o te antenna i te auau motuhake he rohe ahua mowhiti me te porowhita o te roangaru kotahi pea. I te huringa o te auau whakahaere, he pai te neke haere o tenei rohe hohe i runga i nga ringaringa torino, engari ka mau tonu tona ahua me ona ahuatanga hiko, ka taea te whanui whanui.

Ko nga painga nui o tenei antenna ko tana mahi ultra-whanui (te whanui o te 10:1 neke atu ranei he mea noa) me tona kaha ki te whakaputa i nga ngaru polarized porohita. Ko ona ngoikoretanga matua he iti noa te whiwhinga me te hiahia mo te kupenga whangai kai taurite. Kei te whakamahia nuitia i roto i nga tono e hiahia ana ki te mahi whaanui, penei i te Whakatau Hikohiko (ECM), nga whakawhitiwhiti whanui, me nga punaha aro turuki.
