Takiuru-wā pūihi: tātai o ngā āhuatanga me ngā āhuatanga taketake

Whakaröpütia Antennas Takiuru-wā rite wae aronga. Tauira ahu ki te mahi i wavelengths poto. E rite rawa te nuinga o ngā pūrere ki whakaata vysokoprovodimym. E hanga ētahi whakarerekētanga ki te vibrator rōpū. E ratou tetahi atu ranei amplifiers. Me mahara hoki käore te reira e reira e whakaaro ki te tuku hongere.

He aha e te tawhā matua i roto i te momo pūihi roko-wā? Tuatahi o te katoa he mea nui ki te tango ki pūkete te auau o te pūrere. whakaaro hoki e tohunga directivity me te taonga. hoki pā Tāuru parenga ia nga tawhā pūihi.

tauira tātai

hāngai Tātaitanga pūihi e tupu i runga i te roa o te haereere. Ki te whakaaro tatou he tauira ki te vibrator, whakamahia te reflector te momo dipole. Ki te roa o te 20 cm, kia waiho te whanui o te rōpū 30 cm. Na roto i te whakanui ake i te rahi o te whatanga, tīpakohia te rōpū kei te āhuatanga hāngai.

Ko te pūrere ki o koutou ringa

He pūihi roko-wā ki ona ringa takai ki te whakaata ohie, a he pai te vibrator ki te whakamahi ki te taura toronga. Tuatahi whakanohoia tika rewa. E whakaritea whata whakamahi i te mīhini fehokotaki'anga. Tohunga tohutohu ki te tāuta tonu te tīwerawera.

kia whakamahia waea ki te whenua anake. Kei te whakamahia expanders o ngā momo rerekē ki te whakaiti i te auau. E powered e te whāurutau whakapā nuinga tauira. He tika te whatanga o runga ki te tono i te diameter iti. Ko reira tika hoki ki te utu i whakarongo ki te pūurutau raro, e whakarere ana i te te waea. Tei runga i te tauira tātai i runga i te rahi pūihi roko-wā.

Ko te tauira mō te kaiwhiwhi ohie

E hanga rewa pūihi takiuru-wā o te teitei iti mō farii ohie. E whakaaro ana te whakarerekētanga tino noa ki te hei i runga i nga whata e toru. Ki te whakaaro tatou i te pūihi ki tetahi whāurutau, tono te reflector te ki te pūnga. Me mahara hoki käore te reira e te whakaritea te rewa ki te whatanga. Hamama i roto i tenei take, ko te tino onge. Whāurutau i te pūihi eke i roto i te taiapa. Tohunga mea e whakaaro nga tauira tino rongonui ki whāurutau dipole. Ka taea e ratou te mahi i runga i te ngaru poto.

He pūrere ki te whatanga

e kore te pūihi fariiraa ororongo tohaina he kawe ia tiketike. I runga i te mākete i reira he whakaaro ki vibrators whakamuri. whakamahia ratou i te tautoko tika whanui. I te wa ano whakapumautia kau ma'u he whanui iti. Ki te whakaaro tatou i te momo pūihi roko-wā paerewa, te mea he whakaata kotahi. eke whatanga i runga i te turanga e ekeeke. Kei te maha Antennas hokona waho nga kau ma'u. whatanga whakaratohia ratou ki te turanga whānui. whakaaro te kounga teitei ki te hei whakaaro ki whāurutau whakarei. taea hoki te tāuta Vibrators kahore te whāurutau. Tu i roto i tenei take, i reira e he roa iti.

Tauira ki rua whata

UHF takiuru-wā pūihi ki te rua-haora i hanga ki te whakaata i runga i te hongere e toru. mea Tohunga e te tauira i kawe ia rerekē. A, no te tīpako koe whakarerekētanga i ki te whakarongo ki te whakarereke o te tautoko. kia whakatakotoria kau ma'u L-ahuahu. Tino maha, tāuta tenei momo o te pūihi i runga i te tuanui.

Pūrere e tika ana mō te hanga pouaka whakaata teihana. Heoi, e kore e taea e ki te mahi i iarere katoa ratou. I roto i tenei take, nui tei runga i te āhua o te reflector. E whakamahia putanga Modern o momo logoperiodic Antennas ki amplifiers putanga. whakatakotoria i raro i a ratou e tuwhera anake whāurutau. I roto i tenei take, kua eke vibrators i te pokapū o te whatanga. rerekē rewa i roto i te roa. Here nui tei runga i te whanui o te whatanga. Tei kawe ia i runga i te whakarerekētanga o te reflector. kia haere Waea pūihi i te expander.

Antennas whakapae

pūihi Whakapae mō te momo TV logoperiodic tu tū whānui. He maha ngā tauira whakamahi i te rewa roa me te tautoko e anake hanga o te konumohe koranu. Ki te hiahiatia, e taea te mahi i te momo pūihi roko-wā takitahi. Ko reira pai hāngai hoki e kore te mea he mana nui te kaiwhiwhi. mea Tohunga e whakanohoia te taata tei mau tuatahi te. ka anake e taea whakaturia te rewa. hoatu te mahi i muri mai te i te reflector. Ki te whakaaro tatou shoplifting whakarerekētanga, kua ratou e rua vibrators.

E hanga te nuinga tauira kahore tūnga. Whata e ratou i roto i te tūnga whakapae. Hei whakaturia te momo pūihi roko-wā whakamahia āhuatanga putanga whānui o te whakarewa. Me mahara hoki käore te reira e te vai nei te whakarerekē auau tiketike i roto i i tāuta i te tīwerawera te. E tīpakohia anake e whakaaro o te kawe ia tiketike ngā whakaniko i. Tino maha, i reira he whakaaro i runga i te mākete ki te wehenga tawhiti kino. Tuatahi o te katoa, tohunga mea e whai ratou kahore raruraru ki ngaru poto, me te taonga nui rawa. Mai i tauira e tika ti'aturi i runga i te rahi o te pūihi roko-wā tātaitanga.

whakarerekētanga poutū

E mea pinepine i kitea i roto i te toa pūihi roko-wā poutū. kawea tauira tātaitanga i roto i runga i te rahi whatanga. Poutū momo pūihi roko-wā i hanga ki ngā whakaata o kawe ia rerekē. E meinga te nuinga tauira ki whakapā i te whāurutau.

Ka taea hoki te kitea e koe whakaaro kahore amplifiers i roto i toa. Ka rite ki te tikanga, whakamahia ratou whakaata poto, a kua whakaturia vibrators momo ngaru. Tei te iti pūihi auau tīkina i runga i ngā āhuatanga maha. I roto i tenei take, me tango te kaiwhakamahi ki pūkete te ātete o te reflector. I tua atu, he mea e tika ana ki te mohio te momo o te expander. Kua hokona te nuinga o ngā tauira ki te pūmana tikanga.

Ko te taputapu 144 MHz

hanga tenei momo o te pūihi roko-wā te mea tia ki te roa, me kua whakamahia vibrators ki tautoko. Ko te tauira paerewa ngā kotahi tūhono. Amplifiers mō tenei momo pūihi takiuru huinga wā o te mana rerekē. I tua atu, he mea nui ki te mahara e he rerekē i roto i te kawe ia nga whakarerekētanga. E hanga ētahi whakaaro ki te counter. E ratou parenga ia tāuru iti. Tikanga, kua hua ratou ki te putanga vibrator. E whakatakotoria kau ma'u teitei iti. Ki te hiahiatia, ka taea e te hanga he taua momo roko-wā pūihi tetahi tangata.

Hoki e tika o te tuhipoka taumata tiketike o te ātete i roto i te raraunga takiuru momo pūihi wā.

Ki te hiahiatia, e taea te huihui i te tauira i te kāinga. Tohunga mō tenei whakaaro he pou maitai, e, e toaati e te tikanga o te inverter fehokotaki'anga. whakamahia te vibrator e ki te putanga kotahi. Kei te whakaritea te pūihi waea ki te expander. Ka rite ki te tikanga, kua eke ai i te raro o te rewa.

Tauira ki parahi rewa

He pūihi T2 parahi rewa roko-wā noatia mahi i runga i iarere rerekē. tauira Paerewa ngā he titi whāurutau whakaritea nei i te raro o te whatanga. Vibrators mō tauira te tono ki te expander anake. Me mahara hoki käore te reira e te taonga he pūihi ki ngā whakaata whānui. Te nuinga o ratou e taea e rere i iarere iti. Tohunga mea e reira ko te pūrere vahiraa kōaro. Hoki enei extenders e whakamahia ki ngā whakaata whakapā. E rite rawa ētahi tauira ki amplifiers, e kua hono ki te iti.

Pūrere ki maitai rewa

pūihi Takiuru-wā ki te rewa maitai e taea te mahi takitahi. Tohunga tūtohu hoki tenei tautoko kotinga whanui. Te nuinga o ngā tauira i te kawe tiketike, a ko ratou pai hāngai mō te hanga i te tohu. E whakamahia Vibrators i roto i tauira o te tūtohutanga rerekē. I roto i tenei take, te tikanga e nga amplifiers tāuta i te raro o te rewa. Tohunga mea e he reira e tika ana ki te whakatika i te whāurutau roto anake te transistor me te supply mana.

I tua atu, he mea nui ki te mōhio e ka taea te tauira whakaminenga meinga raruraru ki tu te reira. Ki te whakaaro tatou Antennas shoplifting, to ratou he taata tei mau nui. Ka mea humarie whakaritea tika tautoko mua i runga i te taputapu rewa.
