Nkishami rya Antenna, Antenna yikinyabiziga ifite imitungo isa nizindi antene, kandi izahura nibibazo bisa bikoreshwa.
1. Ubwa mbere, ni irihe sano riri hagati yo kwishyiriraho Antenna ya Antenna nubutanze bwayo?
Mu nyigisho, Antenna yashizwe ku modoka nta cyerekezo cyerekezo gifite icyerekezo cya horizontal, ariko kubera imiterere idasanzwe yumubiri wimodoka hamwe numwanya wa Antenna, gushiraho antenne nyayo bifite ubuyobozi, n'imikorere ya Ubu buryo butandukanye butandukanye nubwa Antenna. Imiterere y'Imodoka Imodoka ni idasanzwe kandi iratandukanye mumodoka igana kumodoka.
Niba Antenna yashyizwe hagati yinzu, imirasire ya antenna imbere yuburinganire kandi bwinyuma izakomera gato kuruta icyerekezo cyibumoso no iburyo. Niba Antenna yashizwe kuruhande rumwe, ingaruka z'imirasire ziraruta gato kuruhande. Kubwibyo, rimwe na rimwe dusanga iyo tunyuze muburyo bumwe, ingaruka zitumanaho ni nziza, ariko iyo dusubiye inyuma, ingaruka mbi za antenna ziratandukanye cyane, kuko ingaruka mbi za antenna kumpande zombi zinyuranye.
2. Kuki ibimenyetso byitumanaho bitaziguye mubusabane bwa V / UHF?
Mubisanzwe, v / uhf imirongo ya koncy ifite inzira nyinshi mugihe cyo kohereza, zimwe zigera kubyakira kumurongo ugororotse, kandi bimwe bigera kubyakira nyuma yo gutekereza. Iyo umuraba unyuze mu kibero utaziguye kandi ugaragaza ko wagaragaye mu cyiciro kimwe, itandukaniro ry'imiraba ibiri rivamo gushimangira imbaraga z'ikimenyetso. Iyo imiraba itaziguye kandi yagaragaye iri mu byiciro bitandukanye, iy'ikirenga bikuraho. Nkintera hagati yo kohereza no kwakira radio yimodoka ihinduka igihe igenda, ubukana bwa radio irahinduka cyane, bikagaragara mubimenyetso.
Hamwe numuvuduko utandukanye wo kugenda, intera yo guhinduranya guhindura radio ubukana bwa radiyo iratandukanye. Itegeko ryahinduwe ni: Isumbuye Imikorere yakazi, uburebure bwimbere, kwihuta kwihuta, hejuru yikimenyetso kibanziriza. Kubwibyo, mugihe ibimenyetso bigira ingaruka zikomeye kubitumanaho, urashobora kugabanya buhoro buhoro umuvuduko wimuka, shakisha buhoro buhoro ibimenyetso bikabije, hagarika imodoka itumanaho ritaziguye, hanyuma usubire mumuhanda.
3. Ikinyabiziga Antenna Igikoresho cyangwa Kwishyiriraho Kwishyiriraho nibyiza?
Imodoka nyinshi zikoresha antene zihagaze kubwimpamvu zikurikira: iyambere nuko antenna yanduye ihagaritse idafite icyerekezo cya horizontal, kugirango radiyo igabanuke, bityo radiyo ikoresha ingufu zidakwiye guhuza icyerekezo cya Antenne; Icya kabiri, Antenna ihagaritse irashobora gukoresha ibyuma nkibisobanuro byayo, kugirango iyo antenne ihagaze ishizwemo, kandi kimwe cya kabiri cyibikorwa, kandi igice kirashobora gusimburwa numubiri wimodoka, kidagabanuka gusa Igiciro, ariko kandi cyorohereza kwishyiriraho no gukoresha. Iya gatatu nuko antenne ihagaritse ifata umwanya muto, kandi umuyaga wo kurwanya umuyaga wa Antenne ni muto, bifasha kugenda byihuse.
Duhereye kuriyi ngingo, igice twashyizeho ni kimwe cya kabiri cya Antenne ihagaritse. Kubwibyo, iyo Antenne yashizwemo cyane kuruhande rumwe, radiyo yasohotse na antenne ntabwo ihagaritse imiraba, ahubwo ivanze ryumuhengeri uhagaritse kandi utambitse. Niba antenna yo kwakira kurundi ruhande yakira imiraba ihagaritse, imbaraga zikimenyetso cyakiriwe ziragabanuka (hamwe na polarisation itambitse itambitse), naho ubundi kubimenyetso byakiriwe. Byongeye kandi, Antenna ya Onlique ituma imirasire idahwitse, igaragara nkimirasire yimbere ya antenne irarenze imirasire yinyuma, bikaviramo kuyobora.
4. Nigute wakemura ikibazo cyurusaku cyazanywe na anten mugihe wakiriye ibimenyetso?
Kwivanga urusaku muri rusange bigabanijwemo kwivanga hanze no kwivanga imbere ubwoko bubiri. Kwivanga hanze ni ikimenyetso cyo hanze cyakiriwe na antenne hanze yimodoka, nko kwivanga kw'inganda, indi mirasire y'imijyi ivanze, kwivanga kw'imijyi y'ikinyabiziga, igisubizo nk'iki ni cyo buryo bwiza bwo kwirinda inkomoko yivanga. Mubisanzwe, uburyo bwa FM muri V / UHF bagira ubushobozi bukomeye bwo kurwanya uburere nkubu. Nyuma yikimenyetso gishobora gufungurwa, kugarukira imbere yimashini birashobora gukuraho kwivanga. Kubivanze byimbere, urashobora kugerageza gusa no kumva radiyo idahwitse. Niba kwivanga atari binini, byerekana ko ntakibazo cyo kwivanga muri sisitemu yikinyabiziga. Niba hari ibindi birangaza imbere, ukoresheje umutwaro wubuyobozi uzakemura ibibazo byinshi.
