ʻO Yagi Antenna kahi antenna i hoʻopau ʻia i ka hopena i haku ʻia me kahi oscillator hana (ʻo ka maʻamau he oscillator pelu ʻia), kahi reflector passive, a me kekahi mau alakaʻi passive i hoʻonohonoho ʻia ma ke ʻano like. I ka makahiki 1920, ua hana ʻo Hidetsugu Yagi lāua ʻo Taiki Uta mai ke Kulanui ʻo Tohoku ma Iapana i kēia antenna, i ʻike ʻia ʻo "Yagi Uta Antenna" a i ʻole "Yagi Antenna" wale nō.

ʻAno

1. Kuhikuhi ikaika: Loaʻa i ka antenna ke kuhikuhi maikaʻi a hiki ke hoʻopili i nā nalu lekiō i kahi kuhikuhi kikoʻī. ʻO ke kuhikuhi radiation kiʻekiʻe loa e like me ke kuhikuhi o ka luna hoʻokele, e kāohi pono ana i ka haunaele a me ke komo ʻana i nā kuhikuhi ʻaʻole i kuhikuhi ʻia.
2. Loaʻa kiʻekiʻe: Ke hoʻohālikelike ʻia me nā antenna dipole, ʻoi aku ka kiʻekiʻe o ka loaʻa o ka antenna pepeiaohao a hiki ke hopu maikaʻi i nā hōʻailona mamao, e hoʻomaikaʻi ana i ka maikaʻi o ka hoʻokipa a me ka maopopo.
3. ʻAno maʻalahi: i haku ʻia me nā oscillator hana, nā mea hoʻomālamalama passive, a me kekahi mau alakaʻi passive i hoʻonohonoho like ʻia, he maʻalahi ke ʻano, maʻalahi ke kiʻi ʻana i nā mea hana, haʻahaʻa ke kumukūʻai, a he māmā, paʻa, a maʻalahi hoʻi e hānai.

Noi

1. Kahua kamaʻilio: ʻO ka antenna pepeiaohao RF i hoʻohana ʻia no ke kamaʻilio pōkole a me ka nalu pōkole loa, e like me ke kamaʻilio lekiō mamao loa, a hiki ke hoʻohana ʻia ma ke ʻano he antenna waho no nā mea hoʻonui hōʻailona kelepona paʻalima e hoʻomaikaʻi i nā hōʻailona kelepona paʻalima. Hiki iā ia ke hoʻonui i ka laulā uhi 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 a me ke kīwī, hoʻohana pinepine ʻia ka antenna pepeiaohao microwave e like me ka antenna hoʻokipa kīwī, hiki ke loaʻa nā hōʻailona kīwī ma nā kuhikuhi kikoʻī a hoʻomaikaʻi i ka hopena hoʻokipa.
3. Kahua radar: Ma muli o kona mau ʻano kuhikuhi a me ka loaʻa, hiki ke hoʻohana ʻia ka antenna pepeiaohao nalu millimeter no ka ʻike ʻana i nā pahuhopu i nā ʻōnaehana radar.
4. Nā kahua ʻē aʻe: Loaʻa i ka antenna pepeiaohao nalu Mm nā noi i ka ʻoihana, nā ʻōnaehana loaʻa ʻikepili a me ka nānā ʻana (SCADA), a me nā kumu ʻepekema a me nā lāʻau lapaʻau, e like me ke kamaʻilio uea ʻole ma waena o ka loaʻa ʻikepili mamao a me nā lako nānā, a me ka loaʻa ʻana o ka hōʻailona a me ka hoʻouna ʻana i kekahi mau hoʻokolohua ʻepekema.
Ua hoʻohana nui ʻia ka antenna Yagi ma nā kahua kamaʻilio uea ʻole ma muli o kona ʻano maʻalahi, ke kumukūʻai hana haʻahaʻa, a me ka hana maikaʻi.

QualwaveHoʻolako nā lako Yagi Antennas i ka laulā alapine a hiki i ka 173MHz. Hāʻawi mākou i nā antenna pepeiaohao loaʻa maʻamau o ka loaʻa 7dBi, a me nā antenna pepeiaohao polarized pālua i hoʻopilikino ʻia e like me nā koi o nā mea kūʻai aku.
