Codsiyada ugu muhiimsan ee anteenooyinka iyo amplifiers ee saldhigyada isgaarsiinta satellite-ka waa sida soo socota:
1. Anteenada: Calaamadaha isgaarsiineed ee dayax-gacmeedku waxay u baahan yihiin in laga soo gudbiyo anteenada dhulka lana geeyo dayax-gacmeedka iyo dayax-gacmeedka oo dib ugu soo noqda dhulka. Sidaa darteed, anteenadu waa qayb muhiim ah oo ka mid ah gudbinta calaamadaha, taas oo diiradda saari karta calaamadda hal mar oo wanaajin karta xoogga iyo tayada calaamadda.
2. Amplifier: signalka waa la yareeyaa inta lagu guda jiro gudbinta, sidaas darteed cod-weyneeye ayaa loo baahan yahay si loo kordhiyo xoogga signalka iyo in la hubiyo in calaamaduhu ay gaari karaan satellite-ka iyo kuwa dhulka. Cod-weyneyeeyaha loo isticmaalo saldhigyada isgaadhsiinta dayax-gacmeedku guud ahaan waa cod-weyneeye dhawaqiisu hooseeyo (LNA), kaas oo leh sifooyinka qaylada hoose iyo faa'iidada sare, taas oo hagaajin karta dareenka calaamadaha la helay. Isla mar ahaantaana, cod-weyneeye ayaa sidoo kale loo isticmaali karaa dhamaadka gudbiyaha si loo kordhiyo calaamada si loo gaaro masaafo gudbin dheer. Marka lagu daro anteenooyinka iyo cod-weyneyaasha, saldhigyada isgaarsiinta dayax-gacmeedku waxay u baahan yihiin qaybo kale, sida fiilooyinka RF iyo furayaasha RF, si loo hubiyo gudbinta iyo xakamaynta calaamadaha siman.
