ANT0104 Pūihi Whānui-Arotahi-Ahurangi
| Kaiārahi-mw | He Kupu Whakataki ki te Pūihi Whānui-ā-Ahu katoa |
Te whakauru atu nei i te hangarau ngaruiti rangatira.,(leader-mw) te pūihi whānui-rahi hou ANT0104. Kua hangaia tēnei pūihi kaha kia mahi i runga i te whānuitanga auau mai i te 20MHz ki te 3000MHz, kia pai ai mō ngā momo tono tae atu ki ngā whakawhitiwhiti ahokore, ngā pūnaha radar me ētahi atu.
Ko te whakanuinga mōrahi o tēnei pūihi he nui ake i te 0dB, ā, ko te rerekētanga porowhita mōrahi he ±1.5dB, e whakarite ana i te tuku tohu pono me te ōrite. Ka whakarei ake anō i tana mahi mā te tauira hihi whakapae ±1.0dB, e whakarato ana i te kapinga pai ki ngā taha katoa.
He āhuatanga porowhita poutū tō te ANT0104, he mea tino pai mō ngā tono e pai ake ai te tuku poutū. Hei tāpiri, ko te VSWR ≤2.5:1 me te aukati 50 ohm o te pūihi e whakarato ana i te taurite aukati tino pai me te iti o te ngaronga tohu.
Nā te hoahoa kiato me te pakari e pai ai mō te whakamahi i roto, i waho hoki, ā, nā te mahi maha-ara ka taea te hono atu mā te kore he raru i roto i ngā taiao katoa.
Ahakoa me whakanui ake e koe te kaha o te tohu o tō whatunga ahokore, me whakapai ake rānei i te mahi a tō pūnaha radar, me whakarite rānei kia pono ngā whakawhitiwhiti kōrero puta noa i te whānuitanga o ngā auau, ko te ANT0104 Ultra Wideband Omnidirectional Antenna te otinga tino pai.

| Kaiārahi-mw | Raraunga Whakamātautau |
| Kaiārahi-mw | te ine i te pūihi |
Mō te ine ā-ringa o te tauwehenga aronga pūihi D, ka tautuhia e mātou mai i te whānuitanga o te awhe hihi irahiko pūihi.
Ko te Arotahitanga D te ōwehenga o te mātotoru mana whakapūtanga mōrahi P(θ,φ) Max ki tōna uara toharite P(θ,φ)av i runga i te porowhita i te rohe mara-tawhiti, ā, he ōwehenga kore-ahu nui atu i te 1, ōrite rānei ki te 1. Ko te tātai tatau penei:
Hei tāpiritanga, ka taea te tatau i te ahunga D mā te tātai e whai ake nei:
D = 4 PI / Ω _A
I roto i te mahi, ka whakamahia te tātaitanga logarithmic o D hei tohu i te ahunga o te pūihi:
D = 10 log d
Ka taea te whakamārama i te aronga D i runga ake nei hei ōwehenga o te whānuitanga porowhita (4π rad²) o te whānuitanga hihi pūihi ω _A. Hei tauira, ki te mea ka whiti te pūihi ki te wāhi porowhita o runga anake, ā, ko tōna whānuitanga hihi ko ω _A=2π rad², ko tōna aronga ko:
Ki te tangohia te logarithm o ngā taha e rua o te whārite i runga ake nei, ka taea te whiwhi i te ahunga o te pūihi e pā ana ki te isotropy. Me mōhio ko tēnei ahunga ka taea anake te whakaata i te irahiko tauira ahunga o te pūihi, i roto i te waeine o te dBi, nā te mea kāore te pai o te tuku i te mea ko te ahunga pai rawa atu. Ko ngā hua tatau penei:
3.01 akomanga: : dBi d = 10 log 2 rauemi
Ko ngā waeine whakanui pūihi ko dBi me dBd, arā:
DBi: ko te hua e whiwhihia ana e te irahiko pūihi e pā ana ki te pūtake pūwāhi, nā te mea ko ω _A=4π te pūtake pūwāhi, ā, ko te hua ahunga ko 0dB;
DBd: ko te pikinga o te irahiko pūihi e pā ana ki te pūihi haurua-ngaru rua;
Ko te tātai tahuritanga i waenga i te dBi me te dBd ko:
2.15 akomanga: : dBi 0 rauemi DBD
