I-Antenna yama-walkie-talkies: izinhlobo, imingcele

Lapho uthenga isiteshi somsakazo, ngokuvamile umbuzo mayelana nokuthi ungakhetha kanjani ama-antenna we-walkie-talkie. Kulesi sihloko, sizobheka izinhlobo zokuthola amadivaysi kanye nemingcele esemqoka okufanele icatshangelwe uma ukhetha amadivayisi anjalo.

Kunenani elikhulu lezinhlobo ezahlukene zama-antenna. Zisebenza futhi zenzekile; Ukuthola, ukuthumela nokuthola-ukuthumela; Ngaphandle nangaphakathi; Pin, isibalo, flat, njll Abamukeli kumele bakhethwe kuye ngenhloso nendawo yokufakwa. Isibonelo, uma udinga i-antenna ye-walkie-talkie emotweni, kufanele uqale uqonde ukuthi uzoyiqinisa kanjani: noma ngabe iyoba idivaysi efakiwe, "i-magnetic" noma ifihliwe. Ngokuvamile amadivaysi anjalo afakwa ezimotweni ezikhethekile, afakwa ngaphakathi ophahleni. Kuyiqiniso ukuthi lesi sigameko kufanele sibe ipulasitiki. Ama-antenna e-Mortise abonakala ngokuthembeka kokunamathiselwe kanye ne-aesthetics, kodwa futhi ngokufakwa okuyinkimbinkimbi. Amadivaysi magnetic abonakala kalula ekuqedeni nasekuqedeni, kodwa ngesivinini esiphakeme (noma lapho ushayela ngaphansi kwezihlahla eziphansi) kunengozi yokuhluleka kwedivaysi, okuzolimaza ikhebula nophahla lopende lwemoto.

Uma udinga i-antenna yomsakazo, okuzoba khona ezindlini zakho, khona-ke udinga ukunquma ukuthi yini engcono kuwe - i-transmitter / i-receiver yangaphandle. Ezimweni ezinjalo kungenzeka ukusebenzisa kokubili amaphini namadivayisi afakiwe. Uma izimo zivuma, kunconywa ukuba ufake isitifiketi egcekeni lokuthola nokudlulisa amadivaysi.

Uma kwenzeka udinga i-antenna ye-walkie-talkie ephathekayo, ungasebenzisa izinhlobo ezimbili zamadivayisi. Okuvamile kakhulu amadivayisi we-pin-and-transmit. Amarediyo aphathekayo egqoke ukugqoka asetshenziswe ku-antenna. Lolu hlobo luvame ukusetshenziswa ngamasevisi akhethekile.

Ngokuvamile, kucatshangwa ukuthi i-antenna elula kunazo zonke futhi ethembekile ye-walkie-talkie iyisibhamu. I, ngokungafani nalokho okucatshangwayo, inomdwebo omnidirectional wokusakazwa kwamagagasi omsakazo. Amadivayisi anjalo awadingi amasethingi nesiqondiso eside emthonjeni wokusakaza. Lapha kumkhiqizo onjalo sizoyeka.

Kumele kuqashelwe ngokushesha ukuthi uma ukhetha idivaysi yokuthola, akufanele ukhokhe ngokukhethekile izici ze-antenna, ngoba abakhiqizi bakhombisa ukuthi kukhona idatha eningi ekhethekile (isibonelo, izici zokuzuza, njll) ukuthi umsebenzisi ojwayelekile akakhulumi ngaye. Into esemqoka ukukhumbula ukuthi isikhathi eside se-antenna yakho esikhethiwe, singcono. Kulesi simo, unalo ububanzi obuningi kanye nekhwalithi yokuxhumana. Ipharamitha yesibili ebalulekile yiwona amandla aphezulu wedivayisi. Le nkhomba izoba efanele uma i-antenna yomsakazo isetshenziselwa ngokuhlanganyela nesignali se-signal amplifier. Ngakho-ke, uma uthenga idivayisi, hlola nomdayisi ngamandla akhe amakhulu nokuhambisana nalabo abakhulisa.

Lapha siye sahlola kafushane ukuthi amadivaysi okwamukela ama-walkie-talkie angobani nokuthi yiziphi izimpawu eziphambili. Kodwa kufanele kuhlanganiswe ukuthi ukuze uthole isignali yomsakazo okungcono, kunconywa ukuba ufake i-antenna ngendlela ephakeme kakhulu, ukuze ingavali ekhaya noma izihlahla.
