He aha te pūihi V?
Ko te pūihi AV he pūihi waea ahunga i hangaia e ngā huānga kawe hiko e rua e toro atu ana ki waho mai i tētahi pūwāhi whāngai noa. Ina tirohia mai i runga, ka hangaia e ngā waewae pūihi e rua he hanganga mārama-āhua-V.
Ka taea te kī ko te pūihi V he whakaritenga pai ake o ngā pūihi waea roa e rua. Mā te whiriwhiri i te roa o te waewae me te koki e tika ana, ka taea e te hihi e whakaputaina ana e ngā waea e rua te whakakaha i ngā ahunga kua tohua, ka nui ake te aronga i te pūihi waea roa kotahi.
E honoa whānuitia ana ngā pūihi V ki ngā pūnaha whakawhitiwhiti kōrero auau-teitei, inā koa i te whānuitanga HF. Heoi, kāore tō rātou auau mahi e whakatauhia ana e te roopu pumau anake. Ko te mahi tuturu e whakawhirinaki ana ki te roa hiko o ia waewae, te koki tihi, te tikanga whāngai, te teitei tāutanga, ngā āhuatanga whenua e karapoti ana, me te mea kei te tuwhera, kei te mutu rānei ngā pito waea.
Hanganga me te Mātāpono Whakahaere
Ko te pūihi V noa he mea tito mai i ngā wae waea roa e rua e hono ana ki tētahi pūwāhi whāngai taurite kei te tihi o te V. He rerekē te whakaoho o ngā ia i ngā waewae e rua, arā, he ōrite te rahi me ngā ahunga inamata rerekē kei te pūwāhi whāngai.
Ka whakaputahia e ia waea tōna ake tauira irahiko. Ina tīpakohia tika te āhua o te pūihi, ka taupatupatu ngā poro irahiko matua i hangaia e ngā waewae e rua, ā, ka honoa ki te tuaka pokapū o te V. Mā tēnei tāpiritanga mara ka whakanuia te kaha o te irahiko ki te ahunga e hiahiatia ana, ā, ka whakapai ake i te aronga o te pūihi.
E rua ngā koki e whakamahia ana i te wā e whakaahua ana i te hanganga:
- Ko te koki i waenganui i ngā waewae pūihi e rua ko te koki whakauru, ko te koki tihi rānei.
- Ko te koki i waenganui i te waewae kotahi me te tuaka pokapū he haurua o te koki kua whakaurua.
Ehara te koki tino pai i te uara pumau whānui. Ka rerekē i runga i te roa hiko o ngā waewae pūihi me te auau mahi e whakaarohia ana.

Ngā Antenna V Whakaohooho me te Whakamutu
Ko ngā pūihi V ka taea te wehewehe kia rua ngā whirihoranga.
Ka whakaatahia e te pūihi V tuwhera, he pūihi rānei e whakaata ana i tētahi wāhanga o te ngaru iahiko mai i ngā pito o ōna kaiārahi. Ka hangaia e ēnei whakaata he ngaru tū i te taha o ngā waewae o te pūihi. Ko te tikanga, ka puta he tauira hihi rua-aronga o tēnei momo pūihi, me te hihi kaha i ngā taha e rua e rerekē ana i te taha o te tuaka o te pūihi.
Ka whakamahia e te pūihi V kua mutu ngā kawenga ātete i ngā pito tawhiti o ngā waea e rua. Ka whakaitihia e ngā kawenga ngā whakaata o te iahiko, ā, ka āwhina i te pupuri i te mahi ngaru haere. Ka taea e tēnei te pehi i te irahiko i te taha whakamuri, ā, ka waihanga i tētahi tauira mutunga-ahi e anga ake ana.
Ko te hoahoa kua mutu te tuku i te whanonga ahunga ōrite ake puta noa i te whānuitanga auau whānui, engari ka tohatohahia ētahi mana RF i roto i ngā ātete whakamutu. Nō reira, me whakataurite e te kaihoahoa pūihi te whānui o te hononga, te ahunga, te whai huatanga, me ngā whakaritenga whakahaere-mana.
Te Awhe Auau me te Roa Hiko
E whakamahia whānuitia ana ngā pūihi V tuku iho i te awhe HF mai i te 3 ki te 30 MHz pea nā te mea he roa ngā roangaru o tēnei roopu e whai hua ai ngā hanganga pūihi waea mō ngā whakaurunga whakawhitiwhiti kōrero pumau.
Heoi, ko te pūihi V e tautuhia ana e tōna āhuahanga me te roa hiko, kaua e te whānuitanga auau kotahi. Tērā pea he haurua te roanga ngaru o ia waewae, he kotahi te roanga ngaru, he maha rānei ngā roanga ngaru te roa, i runga i te tauira irahiko me te whakanui e hiahiatia ana.
I te roa haere o te hiko o ngā waewae, ka taea te whakapai ake i te aronga o te pūihi. I taua wā anō, ka puta pea ētahi atu porowhita taha, ā, ka taea e te tauira irahiko te tairongo ake ki te auau, te teitei o te tāutanga, te kawe hiko o te whenua, me ngā ātete hangahanga.
Tauira me te Arotahitanga o te Irahiko
Ko te tauira irahiko o te pūihi V whakakorikori he mea e rua ngā ahunga. Ka honoa ngā mara i hangaia e ngā wae waea e rua hei hanga i ngā porowhita nui e tata ana ki te tuaka pokapū o te V.
Ka whakatauhia te tauira irahiko whakamutunga e ētahi āhuatanga:
- Te roa o ia waewae pūihi
- Kei roto ko te koki i waenganui i ngā waewae
- Auautanga whakahaere
- Te aukati whāngai-ira me te taurite
- Teitei o te tāutanga i runga ake i te whenua
- Te whānui o te waea me te ngaronga o te arataki
- Whirihoranga tuwhera, mutunga rānei
Mā te whakanui ake i te roa o te waewae ka nui ake te aronga, engari ka taea hoki te hanga i ngā taha taha kaha ake. Nā konei, kaua e whakaarohia te whakanui pūihi motuhake mai i te whānui o te hihi, te taumata taha-taha, te ōwehenga mua-ki-muri, me te mahi aukati.

Te Whāngai me te Taurite Āraitanga
Nā te mea he hanganga waea taurite te pūihi V, he mea whāngai noa ki tētahi aho tuku taurite. Mena ka whakamahia he taura coaxial, me whakamahi pea he taura pūmau, he whatunga ōrite rānei hei whakaiti i te iahiko aratau-noa i runga i te taura, hei pupuri hoki i tētahi tauira irahiko ōrite.
Ka rerekē te aukati tāuru me te roa o te waewae, te koki tihi, te auau whakahaere, te teitei o te tāutanga, me ngā hanganga tata. He mea nui te taurite aukati tika hei whakaiti i te mana whakaata me te whakatutuki i te mahi pumau o te pūnaha.
I roto i te whakawhanaketanga pūihi mahi, ka arotakehia e ngā kaihangarau te ngaronga hokinga mai, te VSWR, te tauira irahiko, te whakanui, te polarization, me te whai huatanga i mua i te whakaoti i te āhua o te pūihi.
Ngā Painga o ngā Antenna V
He maha ngā painga mahi a te pūihi V:
- Hanganga waea māmā
- Teitei ake te aronga i te huānga waea roa kotahi
- He iti te utu hanga
- He pai mō ngā tāutanga HF pumau nui
- Te roa o te waewae ngāwari me te hoahoa koki-pito
- Kei te wātea i roto i ngā whirihoranga ngaru-ātaahua me ngā whirihoranga ngaru-haere
Ngā Herenga Hoahoa
He maha anō hoki ngā herenga o ngā pūihi V:
- He nui te wāhi tāutanga e hiahiatia ana mō ēnei i ngā auau iti iho.
- Tērā pea ka puta he ngaru tū kaha i ngā putanga haruru.
- Ka taea e ngā waewae roa o te pūihi te whakaputa i ngā taha roa.
- Ka tino rerekē te mahi i te auau.
- Ka pā pea ngā āhuatanga o te whenua me te teitei o te tāutanga ki te tauira irahiko.
- Ka whakahekehia te whai huatanga o ngā putanga kua whakamutua nā te mea ka mimitihia te mana e ngā kawenga.
Ngā tono noa
Ko ngā pūihi V kua whakamahia i ngā wā o mua i roto i:
- Whakawhitiwhiti reo irirangi HF pūwāhi-ki-pūwāhi
- Ngā teihana tuku me te whiwhi ngaru poto
- Ngā hononga whakawhitiwhiti kōrero pumau tawhiti
- Ngā pūnaha aroturuki reo irirangi me te whiwhi tohu
- Rangahau whakawhitiwhiti kōrero me te mātauranga pūihi
- Ngā whakamātautau waea-pūihi ahunga
- Ngā pūnaha whakawhitiwhiti kōrero mō ngā āhuatanga ohorere me ngā rohe tawhiti
Te Hiranga o te Hangarau
Ahakoa kei te piki haere te whakamahi a ngā pūnaha whakawhitiwhiti kōrero hou i ngā arai kiato, ngā pūihi haona, ngā pūihi whānui, me ngā pūnaha pūihi e whakahaerehia ana e te hiko, he tauira nui tonu te pūihi V i roto i te ariā pūihi.
E whakaatu mārama ana i te pānga o te roa o te ara iahiko, te āhua o te iahiko, te āhua o te pūihi, me te taupatupatu mara ki te ahunga o te irahiko me te ahunga o te irahiko. He mea nui te mārama ki ēnei whanaungatanga ina ako ana i ngā hanganga pūihi matatau ake, tae atu ki ngā rarangi taupatupatu, ngā pūihi ine whānui, ngā pūihi ngaruiti ahunga, me ngā pūnaha whakamātautau pūihi.
Ka whakawhanakehia e RF MISO ngā otinga pūihi me te ngaruiti mō ngā whakamātautau RF, te ine, te whakawhitiwhiti kōrero, te radar, me ngā tono whakauru pūnaha. Mā te māramatanga pakari ki ngā hanganga pūihi taketake ka āwhina i ngā kaihangarau ki te whiriwhiri i ngā hua e tika ana me te aromatawai i ngā tawhā matua pēnei i te whakanui, te polarization, te whānui o te hihi, te aukati, me te tauira hihi.
