Ibihangange mu kirere, bizwi nkiminara ya selile, ni ngombwa mu itumanaho ryacu rya buri munsi.Bitabaye ibyo twaba dufite zero ihuza.Iminara ya selire, rimwe na rimwe yitwa imbuga za selire, ni ibikoresho byitumanaho ryamashanyarazi hamwe na antenne yubatswe yemerera agace kegeranye gukoresha ibikoresho byitumanaho bidafite insinga nka terefone ngendanwa na radio.Ubusanzwe iminara ya selile yubatswe nisosiyete yumunara cyangwa itwara umugozi mugihe yaguye imiyoboro yabo kugirango ifashe gutanga ibimenyetso byiza byo kwakira muri kariya gace.
Nubwo hariho umunara wa terefone ngendanwa, abantu benshi ntibazi ko mubisanzwe bashobora gushyirwa mubwoko bumwe butandatu: monopole, lattice, umusore, umunara wubujura, umunara wamazi, hamwe na pole nto.
A umunara wa monopoleni Byoroheje.Igishushanyo cyibanze kigabanya ingaruka ziboneka kandi biroroshye kubaka, niyo mpamvu uyu munara utoneshwa nabateza imbere umunara.
A umunarani umunara uhagaritse umunara wubatswe hamwe nurukiramende cyangwa mpandeshatu.Ubu bwoko bw umunara burashobora kuba bwiza ahantu harimo gushiraho umubare munini wibibaho cyangwa antenne yisahani.Iminara ya Lattice irashobora gukoreshwa nkiminara yohereza amashanyarazi, umunara wa selile / radio, cyangwa nkumunara wo kureba.
A umusoreni ibyuma byoroheje byubatswe bifatanye ninsinga zicyuma mubutaka.Ibi bikunze kugaragara mubikorwa byiminara kuko bitanga imbaraga zikomeye, zikora neza, kandi byoroshye gushiraho.
A umunarani umunara wa monopole, ariko wiyoberanyije.Mubisanzwe bari mumijyi mugihe bakeneye kugabanya ingaruka zigaragara kuminara nyirizina.Hariho itandukaniro ritandukanye kuminara yibye: igiti kinini cyibabi, igiti cy'umukindo, umunara wamazi, ikibendera, inkingi yoroheje, icyapa, nibindi.
Ubwoko bwa nyuma bwumunara ni akagari gato.Ubu bwoko bwakazu bwahujwe na fibre optique hanyuma igashyirwa kumurongo wakozwe nkumucyo cyangwa inkingi yingirakamaro.Ibi bituma barushaho kugira ubushishozi, mugihe banabegereye hafi ya terefone zigendanwa nibindi bikoresho-inyungu izagaragara neza uko tugenda.Nka umunara naho, utugingo ngengabuzima duto tuvugana bidasubirwaho hejuru ya radiyo, hanyuma wohereze ibimenyetso kuri enterineti cyangwa sisitemu ya terefone.Imwe mu nyungu yongeyeho ingirabuzimafatizo ntoya ni uko zishobora gukoresha amakuru menshi ku muvuduko wihuse bitewe na fibre ihuza.
