revenger Админ. answered 4 years agoKunezinhlobo ezimbili zama-antenna: i-parabolic ne-offset. Ama-Parabolic anokugxila okuqondile, okungukuthi, agxilisa isignali kusuka ku-satellite phakathi nendawo yendingiliza yabo. Akusebenzi kakhulu ukusebenzisa ebusika, njengoba iqhwa linamathela phezulu, elilulaza ikhwalithi yesignali. Ama-antenna e-offset anokugxila okushintshile futhi ane-oval reflection. Ama-antenna athandwa kakhulu, njengoba ungafaka isiguquli esengeziwe ukuze uthole amasathelayithi angu-2-3. Ngaphambi kokuthenga uthi nokukhetha ububanzi balo, nquma ukuthi yiziphi iziteshi ongathanda ukuzibuka. Uma iziteshi ozikhethile zisakazwa ku-satellite eyodwa, uzodinga ukufaka eyodwa yezinhlobo ezimbili zama-antenna, ububanzi bayo buncike endaweni yokumboza yesathelayithi, i.e. indawo yokumboza isathelayithi incane, isignali iba buthakathaka futhi, ngakho-ke, ubukhulu be-antenna bukhulu. Uma ufuna ukusebenzisa amasathelayithi amabili, ibekwe eduze komunye nomunye ku-axis ye-polar, bese uthatha i-antenna eyodwa, ufake iziguquli ezimbili kuyo. Ukuze ubuke amasathelayithi angaphezu kwamabili noma amasathelayithi aqhelelene, faka uthi olunomshini ojikelezayo okuvumela ukuthi uhambise uthi ngokuzenzakalelayo kumasathelayithi athile. Umkhiqizi odume kakhulu wezimpondo zasekhaya yi-Supral.
