isantenna esihlukileyo yekhono
Isiqhawuli se-antenna esikhulu kakhulu yindlela ebalulekileyo yokuxhumana esebenzisa uhlelo lokugcina amandla wokuxhumana kumaqondo esebenza ngokweqile. Le ndlela yekhankatha iqhutywa ngokuthi ibeke amandla we-elektromagnetika kumaqondo omkhulu, engafanele kulo noma yikuphi indawo. Uhlelo lwalo lula kunezinto eziningi ezihlelwe ngokuchanekileyo, okunikeza amandla okuthola kwezingu-10 dBi noma ngaphezulu. Le ndlela yekhankatha iyasebenza kahle kumaqhawuli oludide, okwenza kube yimalwa kakhulu kumaqhawuli aphakathi nezinto, izinhlelo zokuxhumana, nezinhlelo zokuxhumana ze-satellite. Uhlelo lwalo lula kunezinto eziningi ezihlelwe ngokuchanekileyo, okunikeza amandla okuthola kwezingu-10 dBi noma ngaphezulu. Le ndlela yekhankatha iyasebenza kahle kumaqhawuli oludide, okwenza kube yimalwa kakhulu kumaqhawuli aphakathi nezinto, izinhlelo zokuxhumana, nezinhlelo zokuxhumana ze-satellite. Uhlelo lwalo lungeni nezinto ezifanayo ezijwayelekileyo, iziphakathi, nezilayezo, ezihlelwe ngokuchanekileyo ukuze kuthuthukwe ukusebenza kuzimanyano ezithile. Izikhankatha ezikhulu kakhulu zasebenzisa izinto eziphambene nezokwelapha kanye nezokwelapha kakhulu ukuze kuthathelwe kancinci ukungcola kwezixhumo nokuthuthukwa kwezokusebenza. Isebenza kuzimanyano ezahlukene, kusukela kumaqondo we-UHF ne-VHF kuya kumaqondo we-microwave, ukuthi kuthuthukwe ukusebenza kuzimanyano ezahlukene. Isayensi esemqoka kule ndlela yekhankatha iyathuthuka, nezinhlelo ezintsha zifaka phakathi izinto ezithulwe yimvula, izinhlelo zokubeka, nezinhlelo zokulayela ukuze kuthuthukwe kancinci ukungcola kwezixhumo nokuthuthukwa kwezokusebenza.
