Ho sebelisoa lisebelisoa life bakeng sa casing ea UHF hybrid coupler?: Khase ea "hybrid" ea UHF hangata e entsoe ka tšepe, joalo ka aluminium kapa tšepe e se nang tšepe. Lisebelisoa tsena li ke ke tsa ama ts'ebetso ea eona, ha feela e le insulated hantle.

Sebopeho sa mantlha sa UHF hybrid coupler ke sefe?: UHF (Ultra-High Frequency) hybrid coupler e entsoe ka marang-rang a mabeli a likou tse 'nè a hokahaneng hammoho. Likou tse 'ne ke li-ports tsa ho kenya, tse hlahisoang, kakaretso le phapang. Boema-kepe ba ho kenya bo amohela lets'oao, boema-kepe ba tlhahiso bo romella lets'oao, boema-kepe ba kakaretso bo kopanya matšoao a mabeli hammoho, 'me kou ea phapang e tlosa matšoao a mabeli ho e mong. Sebopeho sa "coupler" se khethollang tšebetso le litšobotsi tsa banyalani. Likou tse 'ne, likhoele tsa phetiso le mateano a lithapo tsa phetiso li etsa sebopeho sa mantlha sa "hybrid coupler". Ntle le leha e le efe ea mehaho ena, banyalani ba ne ba ke ke ba khona ho sebetsa ka mokhoa o tloaelehileng.

Ke mang ea lokelang ho abeloa ho sebetsa UHF hybrid coupler?: Motho ea lokelang ho abeloa ho tsamaisa banyalani ba UHF seteisheneng sa khaso o lokela ho ba le boiphihlelo le boiphihlelo bo matla ba tekheniki le lisebelisoa tsa elektroniki. Hape ba lokela ho ba le kutloisiso e utloahalang ea melao-motheo ea ho hasa khaso ea seea-le-moea le bokhoni ba ho rarolla mathata afe kapa afe a ka hlahang. Ho feta moo, ba tlameha ho ba le tsebo e ntle ea puisano le ho rarolla mathata.
