Sebazi reAntenna, ANTENNA ine ANTENNA yakafanana nedzimwe antennas, uye inosangana nematambudziko akafanana mukushandiswa.
1. Kutanga, chii chinonzi hukama pakati peiyo nzvimbo yekuisa yemotokari antenna uye kutungamira kwayo?
Mufundisi, mota antenna yakaiswa pamotokari haina kutungamira munzira yakatwasuka, asi nekuda kwechimiro chisina kujairika chemuviri wemota, iyo chaiyo yekuisa yeNzvimbo yeAntenna ine humwe hutachiona, uye kuita kwe Uku kukonzerwa kwakasiyana neiyo yeiyo nzira yetenna. Iyo nzira yekufambisa yemotokari antennas haina kujairika uye inosiyana kubva kumota kuenda kumota.
Kana iyo Antenna yakaiswa pakati pedenga remba, iyo antenna radiation pamberi uye kumashure mafambiro achave akasimba zvishoma kupfuura mafambiro eruboshwe uye kurudyi. Kana iyo Antenna yakaiswa kune rumwe rutivi, iyo radiation mhedzisiro iri nani zvishoma kune rimwe divi rakatarisana. Naizvozvo, dzimwe nguva tinoona kuti kana tichienda nenzira imwecheteyo, maitiro ekukurukurirana zvakanaka, asi patinodzokera, kutaurirana kwakananga kwakasiyana kwazvo, nekuti iyo antenna radiation yemota yakasiyana.
2. Nei zviratidzo zvekutaurirana zvakananga zvichiteerana mukushandiswa kweV / UHF mobile?
Kazhinji, v / UHF Frequency mafungu ane nzira dzakawanda panguva yekutapurirana, vamwe vanosvika padanho rekugamuchira mumutsara wakananga, uye vamwe vanosvika pakugamuchira nguva yekugamuchira mushure mekuratidzwa mushure mekuratidzira. Kana mafungu achipfuura nepakati peganda rakananga uye fungidziro dzakatarwa dziri muchikamu chimwe chete, iyo masaisai maviri anoguma nekuzvisimbisa kweshoko reSignal. Kana mafungu akananga uye airatidzwa ari mumatanho akatarisana, iwo makurukota anodzungudza mumwe nemumwe kunze. Sezvo chinhambwe pakati pekutapurirana uye kugashira kweiyo redhiyo redhiyo redhasi kuchinja nguva dzose kana iri kufamba, kukura kwenhepfenyuro kwamafungu zvakare inoshanduka zvinoshamisa, iyo inoratidzwa mumuratidziro emukati.
Nekumhanya kwakasiyana kwekufamba, kupindirana kwekuchinja kwekuchinja kweredhiyo yekuwedzera kwakasiyana zvakare kwakasiyana. Mutemo wekuchinja ndewekuti: Iyo yepamusoro yekushanda frequency, ipfupi iyo wavelength, iyo inokurumidza kumhanya kwekufambisa, iyo yakakwira iyo frequency yemukati yemirimo. Naizvozvo, kana chiratidzo chekusarongeka chinokanganisa zvakanyanya kutaurirana
3. Mota antenna vertical kuisirwa kana oblique kuisirwa kuri nani?
Mota dzakawanda dzinoshandisa Vertical Atennas Nezvikonzero zvinotevera: Chekutanga ndechekuti mutungamiri wehunheni haana kutaurwa munzira yakatwasuka, kuti ira redhiyo mukushandiswa kwenharembozha haifanirwe kunetsa kuenzanisa nhungamiro yeAntenna; Chechipiri, iyo Atenna inokwanisa kushandisa simbi simbi seyakajairika Osilcallator, kuti kana iyo yekugadzira yekugadzira inogona kuiswa, uye vamwe vese vanogona kutsiviwa nemuviri wemota, izvo zvisinganyatso kuderedza Mutengo, asiwo unofambisa kuisirwa uye kushandisa. Chetatu ndechekuti antenna antenna anogara pachinzvimbo chidiki, uye kupikiswa kwemhepo kweAntenna idiki, iyo inokodzera kukurumidza kufamba.
Kubva pane ino maonero, chikamu chatakaisa ndeche chete hafu yeiyo vertiki antenna. Naizvozvo, idzo antenna yakaiswa diagonally kune rumwe rutivi, mafungu eredhiyo akabayirwa neAntenna haana kunyorwa mafungu, asi musanganiswa wevasungwa akasvinwa uye akasvinwa mafungu. Kana iyo yekugamuchira antenna yerimwe divi inogamuchira yakagadziriswa mafungu, iyo simba rechiratidzo yakagashirwa inoderedzwa (ine polization yakaderera), uye zvinopesana nezvinopihwa chiratidzo. Uye zvakare, iyo oblique antenna inoita kuti radiation isina kugadzikana, iyo inoratidzwa sezvo radiation yeAntenna yakakura kupfuura radiation kumashure, zvichikonzera kuenderana.
4. Maitiro ekugadzirisa iyo ruzha kupindira yakaunzwa nemotokari antenna kana uchiwana zviratidzo?
Antenna ruzha kupindira inokamurwa kuita mukukanganiswa kwekunze uye kupindira kwemukati miviri mhando. Kupindira kwekunze ndiko kuratidzira kwekupindirana kwakagamuchirwa kubva kuAntenna kunze kwemotokari, sekukanganiswa kwemaindasitiri, kumwe kupindira kwemotokari, mhinduro yekukanganisika ndiyo nzira yakanyanya kunaka yekugara kure nekukanganiswa. Kazhinji, FM mode mu v / UHF bhendi ine kugona kwakasimba kuramba iyi mhando yekukanganisa. Mushure mekunge chiratidzo chacho chinogona kuvhurwa, kudzikisira kutenderera kwemuchina kunogona kubvisa kukanganiswa. Yekukanganisa kwemukati, unogona kungoedza uye kuteerera kune yakasimba redhiyo radio station. Kana kukanganisika kusiri kukuru, kunoratidza kuti hapana dambudziko nekukanganisa kweiyo mota system. Kana paine zvimwe zvinotsausa zvemukati, uchishandisa pane-bhodhi transcessiver ichagadzirisa matambudziko mazhinji.
