revenger Админ. answered 4 years agoKukho iindidi ezimbini ze-eriyali: i-parabolic kunye ne-offset. I-Parabolic igxininise ngokuthe ngqo, oko kukuthi, igxininisa umqondiso ovela kwisathelayithi embindini wesangqa sabo. Akunakwenzeka kakhulu ukusetyenziswa ebusika, njengoko ikhephu linamathela phezulu, elithobisa umgangatho wesignali. Ii-eriyali ze-Offset zinogxininiso olutshintshileyo kwaye zine-oval reflection. Ii-eriyali ezidumileyo ngakumbi, kuba unokufakela isiguquli esongezelelweyo ukufumana iisathelayithi ezi-2-3. Ngaphambi kokuthenga i-eriyali kunye nokukhetha i-diameter yayo, yenza isigqibo sokuba yeyiphi itshaneli ongathanda ukuyibukela. Ukuba iziteshi ozikhethileyo zisasazwa kwisathelayithi enye, kuya kufuneka ukuba ufake enye yeentlobo ezimbini zee-eriyali, ububanzi bayo buxhomekeke kwindawo yokugubungela i-satellite, i.e. incinci indawo yokugubungela i-satellite, i-signal iyancipha kwaye, ngoko ke, inkulu ububanzi be-eriyali. Ukuba ufuna ukusebenzisa iisatellite ezimbini, ibekwe ecaleni komnye komnye kwi-axis yepolar, emva koko thatha i-eriyali enye, faka ii-converter ezimbini kuyo. Ukujonga ngaphezulu kweesathelayithi ezimbini okanye iisathelayithi eziqelelene kakhulu, faka i-eriyali enomatshini ojikelezayo okuvumela ukuba uhambise ngokuzenzekelayo i-eriyali kwiisathelayithi ezichaziweyo. Umenzi odumileyo wee-antenna zasekhaya nguSupral.
