Ungayikhetha njani i-eriyali?I-eriyali yangaphakathi, i-eriyali yangaphandle, i-eriyali yekomityi yokufunxa?

I-eriyali yangaphandle

I-eriyali yangaphandleinokwahlulwa ibe yi-eriyali ye-omnidirectional kunye ne-eriyali yexesha elimisiweyo ngokuxhomekeke kwi-Angle kunye ne-azimuth yendawo yomthombo wemitha.

Umzobo wemitha yangaphakathi ye-antenna ye-omnidirectional

I-eriyali ye-Omnidirectional: oko kukuthi, kumzobo othe tye, imelwe ubukhulu becala njengomthombo wemitha oyi-360 ° symmetrical radiation, edla ngokuthiwa ayingqalanga.Kumzobo othe nkqo, ubonakaliswa ngokuyintloko njengomqadi onobubanzi obupheleleyo.Ngokubanzi, ubuncinci ububanzi bubonke belobe, kokukhona ukuzuza okukhulu.Amalungu aphambili e-eriyali yangaphandle ye-omnidirectional yi-eriyali yokufunxa yeglasi, i-eriyali yentsimbi yeglasi ekhusela umbhobho kunye ne-eriyali yeglu enyibilikayo enyibilikayo.

Umzobo wemitha yendawo yangaphakathi ye-eriyali eyalathiso

I-eriyali yomkhomba-ndlela: I-eriyali apho ugqithiso kunye nolwamkelo lwamaza erediyo omelele ngakumbi kwicala elinye okanye ngaphezulu ezikhethekileyo kwaye zero okanye mncinci kakhulu kwamanye amacala.Injongo yokukhetha i-eriyali esisigxina kukuphucula usetyenziso olufanelekileyo lobungakanani bemitha kunye nokusebenza kokuphakamisa.Injongo ephambili yokukhetha i-antenna esisigxina yokufumana i-antenna kukuphucula uvakalelo lokufumana kunye nokuchasana nokuphazamiseka.I-antenna yangaphandle engundoqo ibandakanya i-antenna yethebhulethi, i-antenna ye-Yagi kunye neyona ndlela ininzi yexesha lomjikelo.

I-eriyali yemagnethi:

I-eriyali yemagnethi: Inzuzo ephezulu ngokwentelekiso, uphawu olukhulu luqulathe i-sucker yeglasi eyomeleleyo yemagnethi, ufakelo oluzinzileyo noluluncedo, kodwa i-glass sucker kufuneka ibhengezwe kumphezulu wesinyithi.Kwintsimi yemodyuli engenacingo, i-antenna yeglasi kunye nemodyuli engenazingcingo zihlala zisebenzisana, ukuze kuphuculwe umgama wonxibelelwano wemodyuli engenazingcingo, njengokufundwa kweemitha ezikrelekrele ezingenazingcingo, oomatshini bokuthengisa, iibhokisi zokubonisa, unomathotholo wesithuthi njalo njalo.

I-eriyali ye-copper rod magnetic: ifana ne-eriyali yesabhokhwe ngokubanzi, kodwa xa ithelekiswa ne-whip glass sucker's izibonelelo zixhomekeke ekukhethweni kweradiyetha enkulu yobhedu yonke i-radiator, ilahleko yayo ye-ohmic incinci, ukusebenza kakuhle kwe-eriyali, ukugquma kobubanzi benethiwekhi.Ilungele izikhululo zothumelo lwedatha ezineemfuno zokusebenza eziphezulu kunye nokuhanjiswa kwemifanekiso kunye nesithuba esiphakathi esithe tye.

I-antenna yeglue eshushu: yeyona ixhaphakileyo i-eriyali yangaphandle, inzuzo yayo iphakathi, ingabizi kakhulu, ixhaphake kwimodyuli yolawulo lonxibelelwano olungenazingcingo, umzila ongenazingcingo, unomathotholo wedijithali njalo njalo.Ubungakanani be-eriyali efanelekileyo yofakelo inokukhethwa ngokweemfuno zendawo yangaphakathi.Ukukhethwa kobukhulu be-antenna kuhambelana nokuzuza.Ngokubanzi, ixesha elide icandelo le-frequency, iphezulu inzuzo.

I-antenna ye-FRP ye-anti-corrosion: kwi-antenna ye-omnidirectional, ukusebenza kwe-antenna ye-FRP ye-anti-corrosion igqwesileyo, i-core iyonke i-vibrator yobhedu, ukusetyenziswa kokutshintshwa kobungqina bokuqhuma, umonakalo ongaphantsi kokusingqongileyo;Isingxobo senziwe ngefayibha yeglasi ekumgangatho ophezulu eyomelezwe kwi-anticorrosion yeplastiki, eneempawu ezintle ezinobungqina obuthathu kwaye idibanisa kakuhle kwindawo yejografi.Ngokukodwa ifanelekile kwisango elide lesango le-IP yedatha yokugubungela, ukuhanjiswa komfanekiso, njl.
