Pūihi VHF ki o koutou ringa: whaiaro-hanga te hoahoa

pūihi VHF - he pūrere tikanga nei hoki te fariiraa i radiation. Ka taea e anake ēnei whakarerekētanga mahi ki tohu poto. Tauira ki tetahi rerekē tetahi i roto i te auau. Pūihi mō te reo irirangi FM ki o koutou ringa ake e haere i runga i nga tohutohu. I roto i tenei take, he mea nui ki te whakaaro i te momo o te kaiwhiwhi. I tua atu, kia tuhia te reira e reira he momo rerekē o Antennas, e rerekē i roto i te hanganga me te tawhā.

Ko te tauira mō te kaiwhiwhi ohie

He he he pūihi hoki FM kaiwhiwhi ki o koutou ringa pinepine atu i runga i te turanga poutū. I te wa ano pauna reira pai ki te whakamahi i te roa iti. Hei whakatika i nga amo whakamahia fehokotaki'anga inverter. Matua hauhake rewa, e ka pupuri i te tautoko. Me kia tōna diameter i te iti rawa 1.2 cm. hoki amplification o te tohu fariiraa te whakamahi i ngā whakaata. whatanga whakatakotoria maha whakarerekētanga i te koki paku.

kia meatia te turanga o te pūihi ki te paparua. I te wa ano e tukua pauna ki te tuhi i runga i te rīpene. Tohunga mea e te ngongo maitai i uru pai. No te tauira ki te aronga kino tono te whakaata. eke huānga mea i runga i te mata o te rewa.

He pūrere ki te whatanga

mahi pūihi mō te reo irirangi FM ki o koutou ringa ake te ki iarere rerekē. Ko te tauira i waenganui i te uara kawenga rerekē, me te taonga. A, no te huihui i te waeine ko reira nui ki te faaineine i te rewa mārō. Tohunga tohutohu ki te whakamahi i whatanga tuwhera kau ki pauna iti. Diameter kia ia i te iti rawa 2.2 cm. Ki te whakaaro tatou he tauira mo farii iti-auau, ka taea te tīpakohia te counterweights i te tira. Ehara i te mea e tika ana ki te tāuta ararewa.

E whakamahia Antennas whakaata i iarere rerekē. I roto i te mākete o akatuke'anga auau ki te puapua. E ratou he nui taonga. Heoi, kia tuhia te reira e e uaua ana ki te whakaputa i runga i to ratou ake ratou. Ka taea e te tūnga mua tahu ki runga ki te whakamahi i te inverter fehokotaki'anga. kia āta kia u te taha o te pūihi. kia whakamahia whata ki diameter o 0.3 cm. hoki e tohe te kōwarotanga pini pokanoa whakamahi whakaata motuhake ki te kawe ia tiketike. E hanga tauira ki tūnga whakapae ki tetahi anake rewa.

Tauira ki rua whata

Ki te rua whata VHF pūihi ki o koutou ringa e haere ki te rewa whanui. He pai mō te ngā farii raupapa Tauira o tenei momo. Tikanga, he uara nui o ngā tauira ātete, e taea ki te mahi i iarere i runga 300 MHz ratou. Maha nga whakaaro i whakamahi whakaata maha. I roto i te whakaminenga o te tauira e hiahia ana ki te whakatutuki i te rewa pokapū. Ka rite ki te tikanga, te whakamahi i tohunga he ngongo diameter iti ki pito whakakoi. Me mahara hoki käore te reira e reira e tauira ki tohutohu. Ai e taea te eke counterweights i koki rerekē. Te roa momo i roto i te pūihi ohie he rite ki te 22 cm.

Hei whakanui i te taonga, e whakamahia korere parahi. He he ano hoki te whakarerekē paki. mahi ratou i te auau o 200 MHz. Aronga o te mahi i te pūihi kia rerekē. Ko te wahi o raro o te pūrere he whatanga taratahi. kia pai kia whakaritea te reflector. kia eke te counterweight i roto i te tūnga whakapae.

Me mahara hoki käore te reira i e i roto i te tikanga ki te hinga i te haruru wāhanga kia whakamahi i te whakaata elongated. Rewa ki te tu pikaunga teitei. He tino pai i polarizations kino Antennas o tenei momo. Heoi, i roto i tenei take, ko te mea e tika ana ki te tango i ki pūkete te momo o kaiwhiwhi me te rohe auau.

Antennas whakapae

Ka taea te huihui Antennas Whakapae ki counterweights o āhua rerekē. E hanga whakarerekētanga Simple i runga i nga rewa rārangi. He he ano hoki te rota o ngā pūrere nui-auau, e kua hangaia ki te whakaata rārangi, eke nei i te raro o te whatanga. Antennas Whakapae i te ōwehenga parenga ia tiketike. E taea e ki te mahi i te auau o 200 MHz ratou.

E rite rawa tokomaha tauira ki counterweights rua. I roto i tenei take e whakamahia te tira e 1.2 cm te whānui. He tika hoki te whakamahi ki te farii kāinga ētahi. E ratou he whakarea tiketike o te poipoi e tu ana. maha whakaturia whata i te koki matau. He Counterweights tika i mua o te pūrere.

whakarerekētanga poutū

E nehenehe o te whakahaere i iarere rerekē Antennas Poutū. Whakarerekētanga o tenei momo i te take amplification tiketike. Ko reira he tino ohie hoki te reo irirangi ki ona ringa ake he pūihi VHF poutū. Tuatahi ti'a ia tatou ki te whiriwhiri i te pae pai, ki te faaineine i roto i mua fehokotaki'anga inverter. Hei whakaoti rapanga ki te vahiraa kino tūtohu te ki te whakamahi i ngā whakaata he pini ma. I te wa ano Me pauna ki te tāuta i te roa nui me te diameter kore e ratou e iti iho i te 0.3 cm. Hei whakarei e tono te arotahi o te whiriwhiringa. kia anake te tāuta te tēpu mua i te koki o 45 nekehanga. Heoi, he mea e tika ana ki te tātai-mua te kaha rewa.

Hei whakanui i te pūmautanga o te hanganga turanga e taea te hanga ki te abutments. Ko te reira i te pūihi FM mo te reo irirangi me o ratou ringa anake ki tia poto e Me tāuta i te teitei iti. Counterweights whakaaetia ki te tinihanga i runga i te pae. kia tango te reira i tiaki o te linings. Kei te hoatu tokanga makehe ki nga rangahau taha, e kua whakaritea ki te rewa. Hei whakanui i te rohe o te manene whatanga tūtohutia o te 25 roa cm.

Ko te taputapu 144 MHz

pūihi VHF i 144 MHz ki o ratou ringa ake ko te pae tika kōpiko ranei. tono rewa i roto i tenei take e ki abutments matahao. I roto i ētahi wā, e whakamahia ana ngā whakaata pākau i. Ko te reira i te pūihi UHF 144 ki ona ringa ki te pou taha. He rite ki te 15 cm te roa paetahi o te tautoko. Kei te whakamahia te mau taea'eo te mua ki te whakapiki ake i te taonga. Ka rite ki te tikanga, kei te eke ratou ki pokohiwi. mahi pūihi VHF i 144 MHz ki o koutou ringa i te tūnga kotahi e rua ranei.

Whakarerekē i 145 MHz

VHF pūihi 145 MHz ki o ratou ringa i hanga rewa poto. E whakaaro ana te whakarerekētanga tino noa ki te hei i te pou e toru. te taonga o te tauira, ko te tino nui. Kaitiaki i Antennas whakamahia ki ngā whakaata he pini ma. Ka taea e te whanau mua kia whakaturia anake i te tikanga o te inverter fehokotaki'anga. I roto i te tauira o te directivity tiketike. mea Tohunga e whakaaetia te pūihi te ki te hanga i te rewa kōpiko.

Tauira ki parahi rewa

He he he pūihi mo te ropu UHF ki o ratou ringa ake ki ngā whakaata o iarere rerekē. kia tāuta pou ki waho pokohiwi ranei. E hanga ētahi whakarerekētanga i roto i te whata taha. Antennas hangaia ki te apuhau nui whakarea. Tuatahi eke rewa. Ka taea te eke Counterweights i te koki paku.

Ko te rauawa diameter tino arotau he 1.2 cm. I roto i tenei take, ko te tika ki te whakamahi i te turanga kaha te rewa. Ki te kōrero tatou e pā ana ki te reflector, he mea e tika ana ki te whakamahi i te pini te momo waea ranei. Ki te hanga i tētahi tauira ohie whakamahia wha counterweights. soldered Pads te whakamahi i te inverter fehokotaki'anga. I tua atu, ki te hanga i te pūrere ki o koutou ringa, eke arai i raro i te rewa. Ka taea e te rohe toreretanga taonga kia tutuki e te tikanga o rauawa lateral.

Pūrere ki maitai rewa

I runga i te rewa maitai i hanga VHF pūihi te ki o ratou ringa ake ki te matahao retinaculum. Counterweights tāuta, te tikanga i tetahi taha. tūtohu ētahi tohunga te whakamahi o ngotungotu ki te diameter o 2.2 cm. Hei whakarei tono te arotahi o te pūrere te pini whakaata, eke nei i te turanga o te pūihi. Hei hono i te tauira e whakamahia ana waea i te rewa. Ko ia tapao e reira e whakaaro ki te matamata taha ano hoki te reira. E ratou he kawe ia tiketike.

Pūrere mō farii tūtohutanga iti

Farii tūtohutanga mō te pūihi VHF iti ki o koutou ringa e haere tino ohie. hauhake te taahiraa matamua te rewa, piri nei ki te tu taha. Kei te maha Counterweights whakamahia ki kaiarahi matahao. whakapumautia ōrite te ki te turanga kaha. I roto i te tauira o tenei momo kia whakamahia whakaata whaiaho. kia tāuta Counterweights i roto i te tūnga whakapae. Hoki amplification o te taonga whakaaetia te ki Maunga te haereere diameter roa o 2.2 cm.

Tauira mō te farii tūtohutanga tiketike

Hoki farii raraunga VHF pūihi mō te 430 ringa MHz e mea ai i te reira ki te rewa maitai. kaha tūtohu ētahi tohunga te whakamahi o anake te whatanga kōpiko. I roto i tenei take, me te whakaritea nga counterweights i te anga turanga. mahi pūihi VHF tikanga ki o koutou ringa i te momo rerekē o ngā whakaata.

Tīmata whakakē huihui pai ki te mau te tira, ka fakahoko waea ki te hono. I tua atu, ki te hanga i te pūrere ki te hiahia o koutou ringa ki te tapahia wha amo ki te diameter o 2.2 cm. Ko te tauira i roto i te MHz 200 kia toru whata taha. kia tāuta Counterweights i te koki o 45 nekehanga. Pou e eke i roto i te raro o te rewa.
