Ko te antenna Cassegrain he antenna whakaata-rua tino pai, ko tona ingoa me tona hoahoa i ahu mai i te telescope Cassegrain. Kei roto ko te whakaata tuatahi (he paraboloid) me te whakaata tuarua (he hyperboloid), kei runga ake i te waahi o te whakaata tuatahi.

Ko te tikanga whakahaere e whai ake nei: ko te haona whangai i te tuatahi ka whiti ngaru hiko ki te whakaata tuarua, ka whakaatahia nga ngaru ki runga i te whakaata tuatahi. Ka whakahiatohia e te whakaata tuatahi enei ngaru ki te kurupae whakarara, tino aronga mo te tuku. Ko tenei ara whatu "kopa" ka taea te whakauru i te whangai ki muri i te whakaataata tuatahi, ka tino whakaiti i te ngaronga o te raina whangai me te whakamaarama i te tiaki.

Ko nga painga matua o tenei antenna ko te nui o te whiwhinga, te iti o te taha taha, te hanganga kiato (ka whakatauritea ki te parapara-roa-roa), me te tuunga o te kai me nga kaiwhiwhi i muri i te whakaata tuatahi, e whakaiti ana i te mate tuku. Ko tana tino kino ko te aukati i tetahi waahanga o te kurupae matua e te whakaata tuarua me tona hanganga tautoko. Kei te whakamahia nuitia i roto i nga whakawhitiwhiti korero amiorangi, irirangi arorangi, me nga punaha radar tawhiti.
