I roto i te mara o te hangarau ngaruiti, he mea nui te mahi a te pūihi hei whakatau i te whai huatanga me te whai huatanga o ngā pūnaha whakawhitiwhiti kōrero ahokore. Ko tētahi o ngā kaupapa e tautohetia ana ko te mea he pai ake te pūihi mēnā he nui ake te whakanui. Hei whakautu i tēnei pātai, me whakaaro tātou ki ngā āhuatanga maha o te hoahoa pūihi, tae atu ki ngā āhuatanga o te **Pūihi Ngaruiti**, te **Whānuitanga Pūihi**, me te whakataurite i waenga i ngā hangarau **AESA (Active Electronically Scanned Array)** me te **PESA (Passive Electronically Scanned Array)**. Hei tāpiri, ka tirohia e tātou te tūranga o te **1.70-2.60Te Pūihi Pūoro GHz Paerewa Gain** hei mārama ki te whakanui me ōna pānga.
Te Mārama ki te Whakanui Antenna
Ko te whakanui pūihi he ine i te pai o te whakahaere, te arotahi rānei o te pūihi i te pūngao auau reo irirangi (RF) ki tētahi ahunga motuhake. Ko te tikanga ka whakaatuhia i roto i ngā desipere (dB) ā, he mahi ia o te tauira irahiko o te pūihi. He pūihi whakanui-teitei, pērā i te **Pūihi Pūoro Paerewa**e mahi ana i te awhe **1.70-2.60 GHz**, ka arotahi te pūngao ki tētahi hihi whaiti, ka taea te whakapai ake i te kaha o te tohu me te awhe whakawhitiwhiti kōrero i tētahi ahunga motuhake. Heoi, ehara i te mea ko te whakanui ake i te kaha he pai ake i ngā wā katoa.

Te Tūranga o te Whānuitanga o te Pūihi
Ko te **Whānuitanga o te Pūihi** e pā ana ki te whānuitanga o ngā auau ka taea e te pūihi te mahi pai. Tērā pea he whāiti te whānui o te whānui o te pūihi whai-rahi, ka whakawhāiti i tōna kaha ki te tautoko i ngā tono whānui, maha-auau rānei. Hei tauira, ko te pūihi haona whai-rahi kua arotauhia mō te 2.0 GHz tērā pea ka uaua ki te pupuri i te mahi i te 1.70 GHz, i te 2.60 GHz rānei. He rerekē, ko te pūihi whai-rahi iti me te whānui o te whānui he nui ake te whakamahinga, ka pai mō ngā tono e hiahia ana ki te tere auau.

Te Aronga me te Taupoki
He tino pai ngā pūihi whakanui-teitei, pērā i ngā whakaata parabolic, ngā pūihi haona rānei, i roto i ngā pūnaha whakawhitiwhiti kōrero tohu-ki-tohu e tino hira ana te kukū o te tohu. Heoi, i roto i ngā horopaki e hiahia ana kia horahia ngā tohu katoa-ahunga, pērā i te pāpāho, i ngā whatunga pūkoro rānei, ka waiho pea he ngoikoretanga te whānui o te hihi o te pūihi whakanui-teitei. Hei tauira, i te wā e tuku tohu ana ngā pūihi maha ki te kaiwhiwhi kotahi, he mea nui te taurite i waenga i te whakanui me te taupoki kia pono ai te whakawhitiwhiti kōrero.

AESA vs. PESA: Te Hua me te Ngāwari
Ina whakatauritea ngā hangarau **AESA** me **PESA**, ko te whakanui i te kaha tētahi o ngā āhuatanga maha hei whakaaroaro. Ko ngā pūnaha AESA, e whakamahi ana i ngā waeine tuku/whiwhi takitahi mō ia huānga pūihi, e tuku ana i te whakanui teitei ake, te urungi hihi pai ake, me te pono ake i ngā pūnaha PESA. Heoi, ko te uaua me te utu nui ake o te AESA kāore pea e tika mō ngā tono katoa. Ahakoa he iti ake te ngāwari o ngā pūnaha PESA, ka taea tonu te whakarato i te whakanui e ranea ana mō te maha o ngā whakamahinga, ka waiho hei otinga whai hua ake i roto i ētahi horopaki.
Ngā Whakaaro Whaihua
He whiringa rongonui te **1.70-2.60 GHz Standard Gain Horn Antenna** mō te whakamātautau me te ine i roto i ngā pūnaha ngaruiti nā te mea he pai te mahi me te whakanui taurite. Heoi, ko tōna pai ka whakawhirinaki ki ngā whakaritenga motuhake o te tono. Hei tauira, i roto i tētahi pūnaha radar e hiahia ana ki te whakanui teitei me te whakahaere hihi tika, he pai ake pea te AESA. He rerekē, ko tētahi pūnaha whakawhitiwhiti ahokore me ngā whakaritenga whānui ka whakatairanga pea i te whānui i te whakanui.
Whakamutunga
Ahakoa ka taea e te whakanui teitei ake te whakapai ake i te kaha me te whānuitanga o te tohu, ehara i te mea koinei anake te mea e whakatau ana i te mahi whānui o te pūihi. Me whai whakaaro hoki ki ngā āhuatanga pēnei i te **Whānui Antenna**, ngā whakaritenga kapinga, me te uaua o te pūnaha. Waihoki, ko te kōwhiringa i waenga i ngā hangarau **AESA** me **PESA** ka whakawhirinaki ki ngā hiahia motuhake o te tono. Hei whakamutunga, ko te pūihi "pai ake" ko tētahi e tino tutuki ana i te mahi, te utu, me ngā whakaritenga whakahaere o te pūnaha e whakatinanahia ana. He painga te whakanui teitei ake i roto i te nuinga o ngā wā, engari ehara i te tohu whānui mō te pūihi pai ake.
