Chowonjezera Phokoso Lochepa (LNA) ndi Filter zimatha kukonza magwiridwe antchito a dongosolo komanso kuthekera koletsa kusokoneza kudzera mu kuwonjezera ma siginolo ndi kuchepetsa phokoso, kusefa ma siginolo ndi kupanga mawonekedwe a spectrum mu kulumikizana kwa satellite.
1. Pamapeto pa kulumikizana kwa satellite, LNA imagwiritsidwa ntchito makamaka kukulitsa zizindikiro zofooka. Nthawi yomweyo, ma LNA amafunikanso kukhala ndi mawonekedwe otsika a phokoso kuti apewe kukulitsa phokoso pamodzi, zomwe zingakhudze chiŵerengero cha chizindikiro-kwa-phokoso cha dongosolo lonse.
2. Zosefera zingagwiritsidwe ntchito polankhulana ndi satellite kuti ziletse zizindikiro zosokoneza ndikusankha bandeji ya pafupipafupi ya chizindikiro chomwe mukufuna.
3. Fyuluta ya band-pass imatha kusefa chizindikiro mu band ya ma frequency yomwe yatchulidwa ndikugwiritsa ntchito posankha band ya ma frequency yomwe mukufuna kuti mulumikizane ndi njira.
