Antenna o le pū fa'ata'amilomiloO se antenna e masani ona faʻaaogaina i faiga fesoʻotaʻiga uaealesi. O lona mataupu faavae o le galue e faʻavae i luga o uiga o le faʻasalalauina ma le polarization o galu eletise. Muamua, ia malamalama o galu eletise e mafai ona i ai ni auala eseese o le polarization, e aofia ai le polarization faʻalava, polarization faʻatulagaina ma le polarization faʻataʻamilomilo. O le polarization faʻalava o lona uiga o le vector o le fanua eletise e oscillates i le itu faʻalava, ma o le polarization faʻatulagaina o lona uiga o le vector o le fanua eletise e oscillates i le itu faʻatulagaina. I le polarization faʻataʻamilomilo, o itu oscillation i itu faʻatulagaina ma faʻalava e iai i le taimi e tasi, ma fausia ai se vector o le fanua eletise e feliuliuaʻi. O le antenna horn polarized faʻataʻamilomilo e ausia ai le faʻasalalauina o galu eletise e ala i se mamanu ma se fausaga faapitoa. E masani ona aofia ai se reflector foliga-horn ma se oscillator e fesoʻotaʻi i le lua o le horn. A ulufale atu galu eletise i le antenna horn polarized faʻataʻamilomilo, latou te ulufale muamua i le lua e ala i le vibrator. O le mamanu o le oscillator e mafua ai ona tele ni ata ma ni refraction o galu eletise i luga o le reflector i totonu o le lua, lea e mafai ona faʻateleina ai le lelei o le faʻasalalauina o galu eletise. E ala i le mamanu fa'ata'atitia sa'o ma le foliga o le reflector, e mafai e le circularly polarized horn antenna ona fetu'una'i le ala o le sosolo o le galu eletise i totonu o le lua e tusa ai ma le tele o le galu eletise ma le tele o le oscillator, ina ia mafai ona gaosia ai le circularly polarized radiation. O le mataupu faavae o le galue o se circularly polarized horn antenna e mafai ona aoteleina e pei o laasaga nei:

E ulufale atu galu eletise i totonu o le lua e ala i le vibrator.

E toe atagia ma toe fa'afo'isia galu eletise i luga o le fogāeleele o le reflector i totonu o le lua, ma suia ai lo latou ala o lo'o fa'asalalauina.

A maeʻa ona toe atagia ma toe faʻafoʻisia le tele o galu eletise, e fausia ai ni faʻasalalauga faʻapolarized faʻataʻamilosaga.

O galu eletise e fa'apola fa'ata'amilomilo e fa'asalalauina e ala i le pū ma fa'aaoga mo feso'ota'iga uaealesi.

I se tulaga lautele, o le antenna horn circularly polarized e ausia ai le faʻasalalauina o galu eletise e ala i se mamanu ma se fausaga faapitoa.O ia antenna e faʻaaogaina lautele i faiga fesoʻotaʻiga uaealesi ma e mafai ona tuʻuina atu le faʻasalalauga o faailoilo e sili atu ona mautu ma faʻatuatuaina.
