Mapaipi obowola a DTH amagwira ntchito yofunikira pakubowola kwa DTH - mosasamala kanthu za ntchito, mtundu wa thanthwe, kuya kwa dzenje kapena chobowolera.Zofunika kwambiri za mipope yobowola yapamwamba kwambiri ndi kulimba, kuuma kwakukulu, kukhazikika, kulondola.

Chitoliro chapamwamba
Kuuma ndi kuvala kukana kuphatikiza aloyi stell, operekedwa ndi dziko pamwamba mlingo wapadera zitsulo wopanga. (chitoliro makulidwe ndi zinthu akhoza wosuta a choise).

Palibe maulalo ofooka
Mwachikhalidwe, ulusi ndi mgwirizano pakati pa chubu ndi mapeto-zidutswa zimakhala zovuta.Kuti tithane ndi vutoli, timawotcherera mafupa kuti akhale amphamvu kwambiri komanso timatenthetsa kuti tizigawo tating'ono ting'onoting'ono tikhazikike bwino.

Kukhazikika ndi kulimba ulusi
Chitsulo chamtengo wapatali chopangidwa ndi alloy, njira yochizira kutentha yoyendetsedwa bwino ndiukadaulo wokhazikika wa ulusi wa API; timasamala kwambiri zonse zomwe sizinanyalanyazidwe kuti zitsimikizire moyo wautali wautumiki, kukhazikika komanso kukhazikika kwa ulusi.
