WHAKAPĀ MAI INĀIANEI

Ko te Yagi Antenna he pūihi mura mutunga i titoa mai i tētahi oscillator hohe (he oscillator takai te nuinga), he whakaata kore mahi, me ētahi kaiwhakahaere kore mahi kua whakaritea kia whakarara. I ngā tau 1920, i hangaia tēnei pūihi e Hidetsugu Yagi rāua ko Taiki Uta o Te Whare Wānanga o Tohoku i Hapani, e mōhiotia ana ko te "Yagi Uta Antenna" ko te "Yagi Antenna" noa iho rānei.

Āhuatanga

1. Kaha te ahunga: He pai te ahunga o te pūihi, ā, ka taea e ia te arotahi i ngā ngaru reo irirangi ki tētahi ahunga motuhake. He rite tonu te ahunga mōrahi o te irahiko ki tō te kaiwhakahaere, ā, ka pehi pai i te raruraru me te pokanoa ki ngā ahunga kāore i te ūnga.
2. Te whakanui ake i te oro: Ki te whakaritea ki ngā pūihi dipole, he nui ake te whakanui o te oro o te pūihi haona, ā, ka pai ake te hopu i ngā tohu tawhiti, ka whakapai ake i te kounga me te mārama o te oro.
3. Hanganga māmā: he mea tito mai i ngā orooro hohe, ngā whakaata kore mahi, me ētahi kaiwhakahaere kore mahi kua whakaritea kia whakarara, he tino māmā te hanganga, he ngāwari te tiki rauemi, he iti te utu, ā, he mama, he pakari, he ngāwari hoki te whāngai.

Tono

1. Mara whakawhitiwhiti kōrero: He pūihi RF e whakamahia ana mō te whakawhitiwhiti ngaru poto me te ngaru poto rawa, pērā i te whakawhitiwhiti reo irirangi tawhiti, ā, ka taea hoki te whakamahi hei pūihi o waho mō ngā whakakaha tohu waea pūkoro hei whakarei ake i ngā tohu waea pūkoro. Ka taea e ia te whakawhānui i te whānuitanga o te kapinga me te whakapai ake i te kaha o te tohu i roto i ngā whatunga Wi-Fi, he pai mō te hono i ngā whare mamao, te whakawhānui rānei i te kapinga tauine nui.
2. I roto i te ao o te pāpāho me te pouaka whakaata, he maha ngā wā ka whakamahia te pūihi haona ngaruiti hei pūihi whiwhi pouaka whakaata, ka taea te whiwhi tohu pouaka whakaata i ngā ahunga motuhake me te whakapai ake i te pānga whiwhinga.
3. Mara radar: Nā ōna āhuatanga ahunga me te whakanui, ka taea te whakamahi i te pūihi haona ngaru mirimita hei kimi i ngā ūnga i roto i ngā pūnaha radar.
4. Ētahi atu mara: He maha ngā whakamahinga o te pūihi haona ngaru Mm i roto i te ahumahi, i ngā pūnaha kohikohi raraunga me te aroturuki (SCADA), me ngā kaupapa pūtaiao me te hauora, pērā i te whakawhitiwhiti kōrero ahokore i waenga i ngā taputapu kohikohi raraunga mamao me te aroturuki, tae atu ki te whiwhinga me te tuku tohu i roto i ētahi whakamātautau pūtaiao.
Kua whānuitia te whakamahinga o te pūihi Yagi i roto i ngā mara whakawhitiwhiti ahokore maha nā tōna hanganga māmā, te utu hanga iti, me te mahi pai.

QualwaveKa hipokina e ngā Antenna Yagi te awhe auau tae atu ki te 173MHz. Kei a mātou ngā antenna haona whakanui paerewa o te whakanui 7dBi, me ngā antenna haona porowhita takirua kua whakaritea kia rite ki ngā hiahia o ngā kiritaki.
