Ngokuthuthuka okuqhubekayo kobuchwepheshe bokuxhumana okungenazintambo, ukutholakala kwenethiwekhi engenantambo sekuyingxenye ebalulekile yokuphila kwethu. Nokho, ezimweni ezithile, ukumbozwa kwamanethiwekhi angenawaya kungase kukhawulwe ngenxa yezinto ezifana nemvelo yendawo, izithiyo zesakhiwo, noma ukuncishiswa kwesignali, okuholela kumasignali abuthakathaka noma angazinzile. Ukubhekana nalolu daba,ama-amplifiers esignali ye-antennazivame ukusetshenziselwa ukuthuthukisa ububanzi bokuhlanganisa amanethiwekhi angenawaya futhi andise ukufinyelela kwawo.
An i-amplifier yesignali ye-antennaiyidivayisi esetshenziselwa ukukhulisa amasignali ezinti ngokukhuphula amandla kanye nokuzuza kwamasignali, ngaleyo ndlela kuthuthukisa amandla okudlulisela amasignali angenantambo. Ekumbozweni kwenethiwekhi okungenantambo, izikhulisi zesignali ze-antenna zingasetshenziswa ezimeni ezahlukahlukene, kufaka phakathi amakhaya, amahhovisi, izindawo zentengiso, izibhedlela, izikole, nokuningi.
Okokuqala, izikhulisi zesiginali ye-antenna zinganikeza ukumbozwa okungenantambo okungcono kumanethiwekhi asekhaya. Emizini eminingi, amasignali angenantambo angase angafinyeleli kuwo wonke amagumbi noma amakhona ngenxa yezithiyo ezifana nezindonga, phansi, nezinye izinto. Ngokusebenzisa ama-amplifiers esignali ye-antenna, amandla esignali anganyuswa, okuvumela amasiginali ukuthi afinyelele izithiyo futhi amboze ibanga elikhulu, ngaleyo ndlela kuthuthukiswe ububanzi bokukhava kanye nekhwalithi yamanethiwekhi asekhaya.
Ngokolunye uhlangothi,ama-amplifiers esignali ye-antennafuthi idlala indima ebalulekile ezindaweni zentengiso. Izindawo zezentengiselwano zivame ukudinga ukukhava ezindaweni ezinkulu, njengenxanxathela yezitolo, izakhiwo zamahhovisi, namahhotela. Ngenxa yezakhiwo eziyinkimbinkimbi kanye nokugcwala kwabantu abaningi, amandla nokuzinza kwamasignali angenantambo kungase kuthinteke. Ngokufaka ama-amplifiers esignali ye-antenna, ukumbozwa kwesignali kungaqiniswa, kuqinisekiswe ukuxhumeka kwenethiwekhi okungenantambo okusheshayo nokuzinzile ezindaweni zentengiso ukuze kuhlangatshezwane nezidingo zabasebenzisi.
Ngaphezu kwalokho, ama-amplifiers amasignali e-antenna nawo abalulekile ezindaweni ezifana nezibhedlela nezikole. Ezibhedlela, ukwethembeka kwamanethiwekhi angenantambo kubalulekile ekuxhumeni izisetshenziswa zezokwelapha kanye nokwenza lula ukuxhumana phakathi kochwepheshe bezokwelapha. Ngokusebenzisa izikhulisi zesignali yezinti, amandla nokuzinza kwamasignali angenantambo kungandiswa, kuqinisekiswe ukutholakala kwenethiwekhi okungenantambo okwanele ngaphakathi ezibhedlela kanye nokuhlinzeka ngezinsizakalo zezokwelapha eziphumelelayo. Ngokufanayo, ezikoleni, isidingo samanethiwekhi angenawaya kubafundi nabasebenzi siyakhula. Ngokufaka izikhulisamazwi zesignali ye-antenna, kungahlinzekwa ukumbozwa okubanzi kwenethiwekhi engenantambo, okuvumela abafundi ukuthi baxhumeke ngaphandle komthungo kunethiwekhi ezindaweni ezihlukene njengamagumbi okufundela, imitapo yolwazi, nezindawo zokulala zabafundi ukuze bafinyelele izinsiza zokufunda futhi bazibandakanye ekufundeni ku-inthanethi.
Ukusetshenziswa kwe-antennaama-amplifiers amasignalikuthuthukisa ngokucacile ukusebenza kwenethiwekhi engenantambo. Okokuqala, bangakhuphula amandla esignali nokuzinza, behlise umthelela wokuncishiswa kwesignali. Ngokwandisa amasignali, ububanzi bokumbozwa kwamanethiwekhi angenawaya bunganwetshwa, futhi izindawo zesignali ezibuthakathaka zingaqiniswa, kuhlinzekwe indawo ebanzi yokuhlanganisa kanye noxhumo oluzinzile. Lokhu kuhumusha ulwazi lomsebenzisi olungcono, okuvumela ukulandwa okusheshayo nokulayishwa kwedatha, nokuzuza ukusakazwa kwevidiyo okushelelayo namakholi wezwi.
Ukwengeza, izikhulisi zesiginali ye-antenna zingathuthukisa umthamo kanye nokuphuma kwamanethiwekhi angenantambo. Ngokwandisa amandla nokuzuza kwamasignali, ama-amplifiers angathuthukisa amandla okudlulisela amasignali angenantambo, athuthukise izinga lokudlulisa idatha kanye nomkhawulokudonsa wenethiwekhi. Lokhu kubaluleke kakhulu ezimweni ezidinga ukuphatha ithrafikhi yedatha enkulu noma ukuxhuma amadivayisi amaningi ngesikhathi esisodwa, njengezindawo zentengiso, izikole, nezibhedlela. Ngokwandisa umthamo wenethiwekhi, izikhulisi zesiginali ye-antenna zingahlangabezana nezidingo zabasebenzisi abaningi ngenkathi zigcina ukusebenza kwenethiwekhi nokuzinza.
Ngakho-ke, ukusetshenziswa kwezikhulisi zesignali ze-antenna kudlala indima ebalulekile futhi kuletha imiphumela ebalulekile ekumbozweni kwenethiwekhi engenantambo. Zithuthukisa amandla esignali nokuzinza, zandise ububanzi bokuhlanganisa, futhi zithuthukise umthamo wenethiwekhi nokusebenza. Ngokusebenzisa izikhulisi zesignali ze-antenna, abasebenzisi bangajabulela ukuzizwisa okungcono kwenethiwekhi engenantambo, kungaba sekhaya, ezindaweni zentengiso, ezibhedlela, noma ezikoleni. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokuxhumana okungenantambo, ukusetshenziswa kwezikhulisi zesignali yezinti kuzoqhubeka nokubamba iqhaza elibalulekile ekuhlinzekeni abantu ngoxhumo oluthembekile nolusebenzayo lwenethiwekhi engenantambo.
Uma ufuna ukuxhumana okwengeziweukugcina isignali Ukusabalala, xhumana nensizakalo yethu yamakhasimende, sizokunikeza uhlelo olubanzi lokumboza isignali.
