Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
I-Coaxial Cable iyilayini yokudlulisa i-electromagnetic exhuma uthi nesamukeli nesidlulisi. Izidingo zesiphakeli ukuthi isiphakeli asiwakhiqizi amandla ngaphandle, sinokulahleka okuphansi nokusebenza kahle okuphezulu, ukuze amandla esidluliseli adluliselwe ku-antenna ngangokunokwenzeka Umthamo wamandla futhi umelane ne-voltage. I-antenna idlala indima yokuguqula amagagasi kazibuthe kagesi adluliselwe esiphakelini abe amagagasi kazibuthe kagesi asakazeka endaweni ekhululekile, noma ukuguqula amagagasi kagesi asakazeka endaweni ekhululekile abe amagagasi kagesi asakazeka kusiphakeli. I-feeder iyishaneli yokudlulisela yamaza kagesi. Kumjikelezo wokuxhumana we-microwave wohlelo lokuphakela i-antenna olwabiwe lweziteshi eziningi, ukusebenza kobuchwepheshe nenkomba yekhwalithi yohlelo lokuphakela i-antenna kuthinta ngqo ikhwalithi yokuxhumana yesiteshi ngasinye se-microwave sohlelo olwabiwe lwe-antenna feeder.

1. INCAZELO YOMKHIQIZO
a. Ukusebenza okuphezulu kwezakhiwo zikagesi, okuholela ekulahlekelweni kwamandla ambalwa kanye nokuphazamiseka kwangaphandle, kuvumela ikhebula ukuthi lisetshenziswe njengekhebula lokudonsa ngokuya nge-broadband, njengokudluliswa kwedijithali, isignali yethelevishini, uxhumano lwenethiwekhi yekhompiyutha yomphakathi, njalonjalo.
b. Ukusabalalisa kwangaphakathi nangaphandle.
