Mfundo yaikulu ndi yakuti nyimbo imakhala ndi mafilimu omwe amamveka bwino, koma oyankhula ena ali bwino kupanga maulendo enieni kusiyana ndi ena. Othandizira amakonzedwa kuti abwerere maulendo apamwamba, opanga maofesiwa amapangidwa kuti abweretse maulendo apansi, ndi zina zotero.
Pokhala ndi malingaliro, magalimoto atsopano a galimoto amamva zodabwitsa pozindikira kuti kayendedwe kalikonse ka galimoto kamakhalapo kokha kamene kamasowa okhulupirira pamtunda umodzi kapena wina. Mwachitsanzo, machitidwe apadera omwe amagwiritsira ntchito olankhula coaxial ali ndi ang'onoting'ono ang'ono omwe amamangidwira. Njira zina, makamaka zomwe zimagwiritsa ntchito oyankhula, zimagwiritsa ntchito ziwonetsero zakunja zomwe zimangopereka maulendo oyenerera kwa okamba bwino.
