Babiri - Inzira ya Radio Urwego Nibintu Bigira ingaruka

Inzira ebyiri - inzira, izwi kandi nka walkie - ibiganiro, ni ibikoresho bifasha itumanaho ryihuse udashingiye kumiyoboro ya selire. Zikoreshwa cyane mumutekano rusange, ubucuruzi, nibikorwa byo hanze. Urutonde rwabo rwibasiwe nibintu bitandukanye, kandi gusobanukirwa nibi bintu birashobora kugufasha guhitamo no kubikoresha neza.

Urutonde rwibintu bibiri - inzira amaradiyo asanzwe afite kuva kuri kilometero nkeya kugeza kuri kilometero mirongo, ariko mubikorwa, akenshi usanga ari mugufi. Mubihe byiza, nkibibaya bifunguye, bitabujijwe cyangwa ahantu hirengeye, ibikoresho byumwuga bifite ibyuma bitanga - byohereza amashanyarazi hamwe na antene ikora neza birashobora kugera kuri kilometero mirongo. Nyamara, mubidukikije bigoye nko kubaka cyane - hejuru, ahantu h'imisozi, cyangwa amashyamba, guhagarika ibimenyetso no kwivanga kwinshi birashobora kugabanya intera ikora kugeza kuri metero amagana cyangwa munsi yayo.

Imbaraga zohereza ni ikintu cyingenzi muguhitamo intera. Muri rusange, imbaraga zisumbuye zisobanura intera ndende yoherejwe. Abasivili bagenda - ibiganiro mubisanzwe bakoresha 0,5 kugeza kuri 2 watt yingufu, mugihe ibikoresho byumwuga bishobora kugera kuri watt 5 cyangwa zirenga. Ubwoko bwa Antenna n'uburebure nabyo ni ngombwa. Hejuru - kunguka antenne yicyerekezo itezimbere cyane - ubushobozi bwitumanaho, kandi gushyira antenne hejuru byongera ibimenyetso.

Ibidukikije ntibishobora kwirengagizwa muguhindura intera ya - inzira ebyiri. Ubushuhe, imvura, na shelegi birashobora gukurura imiraba imwe ya radiyo, mugihe amashanyarazi ya interineti (urugero, kuva hejuru - umurongo w'amashanyarazi hamwe nibikoresho bya elegitoronike) bishobora gutera ibimenyetso. Byongeye kandi, guhitamo inshuro ni ngombwa. VHF (inshuro nyinshi cyane, 30 - 300MHz) ifite uburebure burebure bwumuraba no gucengera cyane ariko gutandukana gukomeye, bigatuma ibera ahantu hafunguye. UHF (ultra-high frequency, 300-3000MHz) ifite uburebure buke bwumuraba no kwinjira cyane ariko bigahagarikwa byoroshye nimbogamizi, bigatuma bikwiranye nibidukikije mumijyi.

Muncamake, itumanaho ryuburyo bubiri - inzira radio ntabwo ari agaciro gahamye; bigenwa no guhuza ibipimo byibikoresho, ibidukikije, hamwe no guhitamo inshuro. Abakoresha bagomba guhindura ibikoresho byabo bakurikije ibyo bakeneye kugirango barebe itumanaho ryiza.
