ʻO ka Prime Focus Parabolic Antenna ke ʻano kuʻuna a koʻikoʻi loa o ka antenna reflector. Loaʻa iā ia ʻelua mau ʻāpana nui: kahi reflector metala i hoʻohālike ʻia e like me ka paraboloid o ka hoʻohuli a me kahi hānai (e laʻa, he antenna pepeiaohao) i loaʻa ma kona kiko kikowaena.

Hoʻokumu ʻia kāna hana ma ke ʻano geometric o kahi parabola: ʻo nā nalu poepoe e puka mai ana mai ke kiko kikowaena e hōʻike ʻia e ka ʻili parabolic a hoʻololi ʻia i loko o kahi kukuna nalu mokulele kuhikuhi kiʻekiʻe no ka hoʻoili ʻana. I ka ʻaoʻao ʻē aʻe, i ka wā o ka hoʻokipa ʻana, ua hōʻike ʻia nā nalu hanana like mai ke kahua mamao a hoʻopaʻa ʻia ma luna o ka hānai ma ke kiko kikowaena.

ʻO nā pono nui o kēia antenna ʻo ia kona ʻano maʻalahi, ka loaʻa kiʻekiʻe loa, ka pololei pololei, a me ke kumukūʻai hana haʻahaʻa. ʻO kona mau hemahema nui ka pale ʻana o ke kukuna nui e ka hānai a me kona ʻano kākoʻo, kahi e hōʻemi ai i ka pono o ka antenna a hoʻokiʻekiʻe i nā pae lobe ʻaoʻao. Eia kekahi, ʻo ke kūlana o ka hānai ma mua o ka reflector e alakaʻi ai i nā laina hānai lōʻihi a me ka mālama paʻakikī. Hoʻohana nui ʻia ia i nā kamaʻilio ukali (e laʻa, ka hoʻokipa TV), ka astronomy radio, nā loulou microwave terrestrial, a me nā ʻōnaehana radar.
