ʻO ka Prime Focus Parabolic Antenna ka mea maʻamau a me ke ʻano kumu o ka antenna reflector. Aia ʻelua ʻāpana nui: kahi mea hoʻoheheʻe metala i hoʻohālikelike ʻia e like me ka paraboloid o ka hoʻololi a me kahi hānai (e laʻa, kahi antenna horn) aia ma kona wahi kiko.

Hoʻokumu ʻia kāna hana ma luna o ka waiwai geometric o kahi parabola: ʻike ʻia nā alo nalu spherical e puka mai ana mai ke kiko kikoʻī e ka ʻili parabolic a hoʻololi ʻia i kahi kukuna nalu mokulele e kuhikuhi pono ana no ka lawe ʻana. ʻO ka mea ʻē aʻe, i ka wā hoʻokipa, ʻike ʻia nā nalu like ʻole mai ke kahua mamao a hoʻopaʻa ʻia i ka hānai ma ke kiko kiko.

ʻO nā pōmaikaʻi koʻikoʻi o kēia antenna ʻo kona ʻano maʻalahi, loaʻa kiʻekiʻe loa, kuhikuhi pololei, a me ke kumu kūʻai haʻahaʻa. ʻO kāna mau hemahema nui, ʻo ia ka paʻa ʻana o ka beam nui e ka hānai a me kāna ʻano kākoʻo, e hōʻemi ana i ka pono antenna a hoʻonui i nā pae lobe ʻaoʻao. Hoʻohui hou, ʻo ke kūlana o ka hānai i mua o ka reflector e alakaʻi i nā laina hānai lōʻihi a ʻoi aku ka paʻakikī o ka mālama ʻana. Hoʻohana nui ʻia ia i nā kamaʻilio ukali (e laʻa, ka hoʻokipa TV), ka lekiō hōkū, nā loulou microwave terrestrial, a me nā ʻōnaehana radar.
