kungani kuthiwa uthi lwerabha

I-antenna iyithuluzi elisetshenziselwa ukwamukela nokudlulisa amaza omsakazo, futhi idlala indima ebalulekile kwezokuxhumana nobuchwepheshe besimanje.Futhi kungani ngezinye izikhathi izimpondo zibizwa ngokuthi “izimpondo zenjoloba”?Igama livela ekubukekeni nasekuphatheni kothi.Izimpondo zenjoloba zivame ukwakhiwa ngezinto zenjoloba, ezithambile, ezihlala isikhathi eside futhi ezingangeni manzi, ngakho-ke zisetshenziswa kakhulu ekwenzeni i-antenna.Ama-antenna enjoloba awagcini nje ngokubukeka kwesitayela, kodwa futhi anokuqina okuhle nokusebenza okuzinzile, ngakho athandwa ngabathengi.

Izimpondo zerabhaaklanywe futhi akhiqizwa ngobungcweti obucophelelayo kanye nobuchwepheshe ukuze kuqinisekiswe ukuthi anganikeza ukwamukela isignali ezinzile kanye nokudluliselwa ezindaweni nezimo ezihlukahlukene.Ama-antenna enjoloba ngokuvamile awangeni amanzi, angangenwa uthuli, futhi angashaqisi, futhi afanele izimo ezihlukahlukene njengangaphandle, ukufakwa emotweni, kanye nemishini yokuxhumana yeselula.Ukubukeka kwayo okuthambile nokokusebenza kwenza i-antenna yerabha ibe lula ukuyifaka nokuyiphatha, okulethela abasebenzisi ukuzizwisa okulula nokunethezekile.

Ngaphezu kwezinzuzo zokubukeka nezinto ezibonakalayo, izimpondo zenjoloba nazo zisebenza kahle ngokusebenza.Ingakwazi ukwamukela nokuthumela amasignali omsakazo ngempumelelo ukuqinisekisa ukuzinza nokuthembeka kokuxhumana.I-antenna yerabha futhi inekhono elihle lokunqanda ukuphazamiseka futhi ingagcina imiphumela emihle yokudlulisela isignali ezindaweni eziyinkimbinkimbi zikazibuthe, inikeze abasebenzisi umuzwa wokuxhumana ocacile futhi ozinzile.

Emakethe, izimpondo zenjoloba zisetshenziswa kakhulu ezintweni zokuxhumana ezehlukene, njengama-walkie-talkies, imishini yokuxhumana egibele emotweni, omakhalekhukhwini, nemishini yenethiwekhi engenantambo.Osayizi bayo abahlukahlukene namamodeli angahlangabezana nezidingo zamadivayisi ahlukene futhi anikeze abasebenzisi ukukhetha okwengeziwe.Ama-antenna enjoloba nawo ahlolwe ikhwalithi eqinile kanye nesitifiketi ukuze kuqinisekiswe ukuthi imikhiqizo ithobela izindinganiso zamazwe ngamazwe kanye nezidingo zemboni, ihlinzeka abasebenzisi isiqiniseko sekhwalithi esithembekile.

Ngokuvamile, izimpondo zenjoloba zizuze ukuqashelwa kabanzi nokwethenjwa ngokubukeka kwazo kwesitayela, ukusebenza okuphezulu kanye nekhwalithi ezinzile.Njengengxenye ebalulekile yemishini yesimanje yezokuxhumana, izimpondo zenjoloba zizoqhubeka zidlala indima ebalulekile, zilethe ukunethezeka nokunethezeka ekuxhumaneni nasekuphileni kwabantu kwansuku zonke.
