Mā te pou arataki, te tīwiri whakarārangi rānei e whakaurua ana mā roto i te pakitara arataki ngaru ka whakauruhia he tauhohenga ā-rohe. Ko tōna whānui, te hohonu o te urunga me tōna tūranga e pā ana ki te kore haere tonu e whakatau ana mēnā he capacitive, he inductive rānei te pānga, me te kaha o tana whakarerekē i te taurite.
Ko te urunga papaku ka puta he whakatikatika iti. I te toronga atu o te pou ki roto i te aratohu, ka rerekē te kaha o te oro, ā, ka taea te whiti i te oro. Nā tēnei ka whai hua ngā tīwiri whakahāngai mō te whakatikatika taiwhanga, te tapahi whakaputa me te utu mō ngā manawanui kāore e taea te matapae tino tika i te wā hoahoa.
Ngā painga o te whakataurite ka taea te whakarite
- ka taea te whakarite i te whakataetae i a koe e aroturuki ana i te ngaronga whakahoki, te VSWR rānei;
- e rua, neke atu rānei ngā tīwiri e whakarato ana i te mana whakahaere tāpiri mō te rahi me te āhua;
- ka taea e te whakatikatika te utu mō te urutau, te tirotiro, te piko, te kawenga rānei;
- ka taea te raka i te tautuhinga whakamutunga i muri i te manatoko.
Ko te whānui o te whānui e whakatauhia ana e te hanganga katoa, ehara i te mea nā te tīwiri anake. Ka taea e te nui o te urunga te hanga i te haruru koi, te whakanui ake i te ngaronga, te whakararuraru i ngā aratau teitei ake, te whakaiti rānei i te whakahaere mana. Nō reira, me mahi te whakahāngai puta noa i te whānuitanga mahi katoa kaua i te kotahi auau anake.
Ko ngā pou me ngā tīwiri he mea whakauru noa ki rotongā urutau arataki-ngaru-ki-whakakotahime ētahi atu wāhanga arataki ngaru me whakawhiti te mara i waenga i ngā hanganga tuku rerekē.

Ngā Whakaiti Vane Nekeneke
Ka huri te whakaitiiti o te hiko o tētahi vane dielectric nekeneke mā te neke i roto i ngā rohe o ngā kaha rerekē o te mara hiko. I waenganui o te mara aratau-matua, ka nui ake te pūngao ka mimitihia e te vane; i te taha o te pakitara taha, ka ngoikore te mara, ā, ka heke te whakaitiiti. Ka taea e te tikanga te whakaiti i te tohu ka taea te whakarerekē me te kore e whakarerekē i te ara arataki ngaru.
Ngā Ngaronga Arataki Ngaru me te Kore-ōrite o te Āraitanga
He hononga te whakaiti me te kore taurite engari he rerekē. Ka whakahokia e te kore taurite tetahi wāhanga o te pūngao taupatupatu ki te pūtake, ko ngā mate hiko me ngā mate uruhanga ka huri i tetahi wāhanga o te pūngao whakamua hei wera.
Ko ngā pūtake matua o te pirau ko:
- ngā whakaata mai i ngā kaupae, ngā piko, ngā tirotiro, ngā āputa flange, ngā wāhanga hē rānei;
- te ngaronga o te ara iahiko i puta mai i te iahiko mata i roto i ngā pakitara ara iahiko;
- te ngaronga hiko-kore mai i ngā matapihi, i ngā tautoko, i ngā mimiti, i ngā wāhanga kua whakakīia rānei;
- te taratara o te mata, te poke, te waikura me te kore e pai te pā atu ki te hiko.
He rite anō te mahi a te arataki ngaru ki tētahi hanganga whakawhiti-teitei. Kāore ngā auau i raro i te tapahi o te aratau kua tīpakohia e horapa noa, ā, ka tino whakaitihia. Nā tēnei take, me whakaū te awhi whakahaere, te rahi o te arataki ngaru me te aratau e hiahiatia ana i mua i te arotautanga o te taurite.
4. Ngā Whakawhiti, Ngā Āhuatanga me te Hononga Flange
Mā te whakawhiti, mā te urutau rānei ka huri haere te mara i waenga i ngā rahi arataki ngaru rerekē, ngā aronga, ngā pāpāho tuku rānei. Ko te tikanga, he whānui ake te taurite o ngā whakawhāititanga i te kotahi taahiraa koi, engari he pai ake te whakawhiti taahiraa kiato ina iti te wāhi.
Ngā urutau arataki-ngaru-ki-whakakotahiwhakakotahihia he whakawhiti ā-ringa me tētahi pūwero, he pūwhakarewa rānei e whakaoho ana i te aratau arataki ngaru e hiahiatia ana. Me mahi tahi te tūnga pūwero, te mokowā poto whakamuri me tētahi huānga whakahāngai puta noa i te awhi kua tohua.
He aha te hiranga o te whakarārangi i ngā flange
Ko ngā wāhanga arataki ngaru he mea hono mā roto i ngā flange. Ko tā rātou mahi he pupuri i te tūnga ā-mīhini, he whakarato i te whakapā hiko pono, me te whakaiti i te turuturu me te whakaata ā-roto. Ka taea e te āputa, te āputaputa, te mata hiri kua pakaru, te pēhanga pūtu kore taurite rānei te whakararu i te haere tonu, inā koa i ngā roangaru poto ake.

Ngā Karapa Maamaa me te Tika
He pai te mahi a ngā flange whakapā noa ina he papatahi, he ma, he tika te tūnga o ngā mata hono. I ngā auau teitei ake, ko ngā hapa iti o te rahinga e tohu ana i te wāhanga nui ake o te roanga ngaru, nō reira ka nui ake te hiranga o te whakaotinga mata, te tūnga arataki me te taipana pūtu.
Ngā Tirotiro Huihuinga Whaihua
- whakaū kei te whakamahia e ngā wāhanga e rua te rahi o te arataki ngaru me te paerewa hototahi o te flange;
- horoia ngā mata e hono ana, ka tirotirohia mēnā he pakaru, he kopa, he waikura rānei;
- whakarārangihia ngā pūaha i mua i te whakakīkī i ngā here;
- whakaukia ngā pūtu kia ōrite kia noho rite tonu ngā mata o te flange;
- manatokohia te ara kua huihuia mā te whakamahi i tētahi tātari whatunga whārite kua whakatikatikaina.

Hononga Whakakākā
Ka whakamahia e te kōkō he mowhiti, he awaawa rānei kua huna ki te taha o te pūaha hei whakahaere i te iahiko i te hononga. Ina tika te rahi mō te awhi whakahaere, ka taea e ia te whakaiti i te aro ki tētahi āputa miihini iti, me te whakapai ake i te hononga hiko. Nā te mea he whakawhirinaki te kōkō ki te auau, me taurite tōna āhua ki te awhi e hiahiatia ana.
Me pēhea te Manatoko i te Taurite o te Aratohu Ngaru
- Whakatikatikahia he tātari whatunga whārite i ngā papa tohutoro e tika ana.
- Inehia te S11, te ngaronga whakahoki rānei puta noa i te awhe mahi katoa, kaua i te auau kotahi.
- Tahurihia te hua ki te VSWR mēnā koinei te whakatakotoranga o te kaupapa.
- Whakatikatikahia ngā tīwiri whakarārangi, ētahi atu huānga rerekē rānei, kia iti noa te pikinga i a koe e mātakitaki ana i te horomitanga katoa.
- Tirohia anō i muri i te whakakīkī whakamutunga, te whakatautau i te pāmahana me te tāutanga o ngā wāhanga tata.
Ka tautuhia he hua pai e te whakatakotoranga o te pūnaha. Kāore pea e ranea te pūwāhi whakaata iti kotahi mēnā he whānui te whānui o te whānuitanga o te raraunga e hiahiatia ana e te tono, he pumau te whakahaere hiko, he mahi auau rānei i muri i te huihuinga.
Me pēhea te whiriwhiri i tētahi tikanga taurite
- Ngā Ārai:kiato, pumau, ā, e tika ana mō tētahi urupare auau kua hoahoatia.
- Ngā pou, ngā tīwiri rānei:he mea whakarite, he mea whai hua hoki mō te whakatikatika i ngā ātete hanga.
