Ee. Leha ho le joalo, li-antenna tsa pele li ne li sebelisa li-feeders tse bataletseng, tseo e neng e se likhoele tsa coaxial.
Lithapo tsa RF coaxial li hloka ho utloisisoa ka likarolo tse peli.
RF: RF e bua ka maqhubu a motlakase a khonang ho khanya sebakeng, ho tloha ho 300kHz ho isa ho 300GHz.
RF ke radio frequency current, shorthand bakeng sa-frequency alternating electromagnetic wave.
Alternate current e fetohang makhetlo a ka tlase ho 1000 ka motsotsoana e bitsoa low{1}}frequency current, 'me e fetohang makhetlo a fetang 10000 ka motsotsoana e bitsoa high{3}}frequency current. RF e phahame-khafetsa ea hona joale.
RF (300K-300G) ke sehlopha sa maqhubu a holimo ka har'a sekhahla sa maqhubu a holimo (ho feta 10K).
Ka khopolo ea elektronike, ha hona joale e phalla ka mokhanni, ho thehoa matla a khoheli ho pota-pota mokhanni; ha motlakase o fapanyetsana o phalla ka conductor, ho thehoa sebaka se fapaneng sa motlakase ho pota-pota mokhanni. Sena se bitsoa leqhubu la motlakase.
Maqhubu a motlakase a nang le maqhubu a ka tlase ho 100kHz a monngoa ke bokaholimo ba Lefatše 'me ha a khone ho fetisoa ka nepo. Leha ho le joalo, maqhubu a motlakase a nang le maqhubu a ka holimo ho 100kHz a ka hasana moeeng 'me a bonahatsoa ke ionosphere karolong e ka ntle ea sepakapaka, a nolofalletsa phetisetso{3} e telele.
Re bitsa{{0}maqhubu a maqhubu a motlakase a phahameng a nang le{1}}maqhubu a malelele a phetiso ea radio frequency (RF).
Theknoloji ea RF e sebelisoa haholo puisanong e se nang mohala; lisebelisoa tsa thelevishene tsa cable li sebelisa phetiso ea RF.
Coaxial cable: Hobane li-conductor tse peli (conductor ea ka hare / ka ntle) ha li tšoane mabapi le mobu, ka mokhanni o le mong oa ka hare o teng sebakeng sa mokhanni oa ka ntle oa cylindrical, o bitsoa "coaxial cable."
Tšobotsi ea lithapo tsa coaxial ke hore lebala la magnetic ha e le hantle le koaletsoe ka har'a sekontiri se ka ntle, se lumellang tšebeliso ea maqhubu a holimo.
Tlhokomeliso: Kondaktara ea ka ntle ea thapo ea coaxial ke conductor le layer e sireletsang (e sebetsa joalo ka loop 'me e fana ka tšebetso e thibelang-tšitiso).
Mohala oa coaxial o sebelisetsoang ho fetisa matšoao a RF o bitsoa "RF coaxial cable."
Letšoao le amohetsoeng ke antenna le fetisetsoa pheletsong e ka pele ka mohala oa phepelo, 'me tlhahiso ea lets'oao ho tloha pheletsong e ka pele le eona e fetisetsoa ho lisebelisoa tse fapaneng tse amohelang ka mohala oa phepelo.
Matsatsing ana, hangata re bona likhokahano le phepelo ea phepelo li sebelisoa lits'ebetsong tsa mats'oao tse holisang mats'oao joalo ka-litora tsa pele tsa mohala oa mohala (China Mobile, China Unicom, China Telecom, joalo-joalo), lithanele le likamore tse ka tlase.
