ʻO Yagi Antenna kahi antenna i hoʻopau ʻia i haku ʻia me kahi oscillator ikaika (ʻo ka mea maʻamau he oscillator folded), kahi hōʻike passive, a me kekahi mau alakaʻi passive i hoʻonohonoho like ʻia. I ka makahiki 1920, ua haku ʻo Hidetsugu Yagi lāua ʻo Taiki Uta mai ke Kulanui ʻo Tohoku ma Iapana i kēia antenna, i kapa ʻia ʻo "Yagi Uta Antenna" a i ʻole ka "Yagi Antenna".

1. Ke alakaʻi ikaika: He kuhikuhi maikaʻi ka Antenna a hiki ke kuhikuhi i nā nalu lekiō ma kahi kuhikuhi kikoʻī. ʻO ke kuhikuhi radiation kiʻekiʻe e like me ko ka luna hoʻokele, me ka hoʻopau pono ʻana i ka clutter a me ke keakea ʻana i nā kuhikuhi ʻaʻole i hoʻopaʻa ʻia.
2. Loaʻa kiʻekiʻe: Ke hoʻohālikelike ʻia me nā antenna dipole, ʻoi aku ka kiʻekiʻe o ka antenna horn a hiki ke hopu maikaʻi i nā hōʻailona mamao, hoʻomaikaʻi i ka maikaʻi o ka hoʻokipa a me ka mālamalama.
3. Hoʻolālā maʻalahi: i haku ʻia me nā oscillators ikaika, nā mea hoʻonaninani passive, a me nā alakaʻi passive i hoʻonohonoho like ʻia, maʻalahi ke ʻano, maʻalahi nā mea e loaʻa ai, haʻahaʻa ke kumukūʻai, a māmā, paʻa, a maʻalahi hoʻi e hānai.

1. Ke kahua kamaʻilio: RF horn antenna i hoʻohana ʻia no ka hawewe pōkole a me ka ultra shortwave kamaʻilio, e like me ke kamaʻilio lekiō lōʻihi, a hiki ke hoʻohana ʻia e like me nā antenna waho no nā mea hoʻonui hōʻailona kelepona e hoʻonui i nā hōʻailona kelepona. Hiki iā ia ke hoʻonui i ka laulā a hoʻomaikaʻi i ka ikaika hōʻailona ma nā pūnaewele Wi Fi, kūpono no ka hoʻopili ʻana i nā hale mamao a i ʻole ka hoʻonui ʻana i ka uhi nui.
2. Ma ke kahua o ka hoʻolaha ʻana a me ke kīwī, hoʻohana pinepine ʻia ka antenna horn microwave ma ke ʻano he kīwī e loaʻa ana i ka antenna, hiki ke loaʻa i nā hōʻailona televise ma nā kuhikuhi kikoʻī a hoʻomaikaʻi i ka hopena hoʻokipa.
3. Radar kahua: Ma muli o kona kuhikuhi a loaʻa nā hiʻohiʻona, millimeter wave horn antenna hiki ke hoʻohana no ka ʻike ʻana i nā pahuhopu i nā ʻōnaehana radar.
4. Nā kahua ʻē aʻe: Mm wave horn antenna i loaʻa i nā noi i ka ʻoihana, ka loaʻa ʻana o ka ʻikepili a me ka nānā ʻana i nā ʻōnaehana (SCADA), a me nā kumu ʻepekema a me nā lāʻau lapaʻau, e like me ke kamaʻilio uila ma waena o ka loaʻa ʻana o ka ʻikepili mamao a me nā lako nānā, a me ka hōʻailona hōʻailona a me ka lawe ʻana i kekahi mau hoʻokolohua ʻepekema.
Ua hoʻohana nui ʻia ʻo Yagi antenna i nā kahua kamaʻilio kelepona ma muli o kona ʻano maʻalahi, haʻahaʻa haʻahaʻa ke kumu kūʻai, a me ka hana maikaʻi.

Kaʻaleʻaleʻanā lako ʻo Yagi Antennas e uhi i ke alapine a hiki i 173MHz. Hāʻawi mākou i nā antenna horn maʻamau o ka loaʻa 7dBi, a me nā antenna horn polarized pālua e like me nā koi o nā mea kūʻai aku.
