Guhitamo antenne yo gutanga

Antenne yakira ikimenyetso cya satelite, kimwe na verisiyo isa nayo, biterwa numuraba uturuka kuminara yubutaka. Niba ari intege nke, noneho ibiganiro bizaba bifite ubuziranenge. Kubwiyi mpamvu, ugomba gutekereza intera igasubiramo hanyuma ukagura amplificateur zidasanzwe. Kandi, ntukibagirwe uko ikirere cyifashe. Kugirango wirinde amakosa, antenne yo gutanga igomba guhitamo, hitabwa kumategeko akurikira:

• igishushanyo kigomba gukora muburyo bwakiriwe bwa 300 – 3000 MHz;
• gutera imbere bigomba kuba bigereranijwe nintera igana ku munara wubutaka;
• ibipimo by’imbaraga bigomba guhuzwa kugirango bifate umuraba;
• ahantu hafunguye cyangwa mumashyamba, ibicuruzwa bitandukanye biragurwa.

Icyitonderwa! Guhitamo antenne ugereranije na diameter ya deflector biroroshye. Nibyiza kugura ibicuruzwa bifite ibipimo bya gride ikurikira: niba uyikoresha asabye cm 90, antenne yashyizweho ya metero 1,2 izatanga kwakira neza no mubihe bibi.

Nigute ushobora kumanika no gushiraho ibiryo bya satelite?

Kugirango ushyire ibiryo bya satelite murugo, uzakenera ibikoresho bikurikira:

• umugozi wagutse kuri socket 3;
• gukubita cyangwa gutobora hamwe na drill ya diameter isabwa kugirango ukosore bracket hamwe na ankeri cyangwa hamwe na dowel;
• imirongo ya mm 13 na mm 10 z’ubunini (nibyiza bibiri);
• Amashanyarazi ya Phillips;
• inyundo;
• kaseti ifata cyangwa amasano ya plastike.

Iyo uteranije antenne, komeza witonze, hanyuma ntuzibagirwe kumesa. Ugomba gukuramo ibice byinshi kubantu bahindura . Imwe iranyeganyezwa kuruhande rwiburyo, iyakabiri – ibumoso hamwe nuhindura. Ntabwo bikwiye gukurura cyane. Kimwe nikurikizwa kuri antenne ubwayo. [ibisobanuro id = “umugereka_3701” align = “aligncenter” ubugari = “640”]
Ikoreshwa ryamamaye ryinshi mugihe ushyizeho ibiryo bya satelite kuri satelite eshatu [/ caption] Agace kagomba gushyirwaho kurukuta. Ibikurikira, ugomba kumanika antenne kugirango yerekeze mu majyepfo cyangwa mu majyepfo yuburasirazuba. Nyuma yibyo, ugomba kurambura umugozi wo kwagura no guhuza TV muburyo butaziguye cyangwa kubakira. Byose, iyi niyo iherezo ryikibazo. Mu gusoza, twavuga ko igiciro cyibiryo bya satelite kigabanuka. Vuba, abantu bose bazashobora kwigurira “ibintu byiza” kandi barebe imiyoboro myinshi yo guhitamo. Kuva kubakiriya ikintu kimwe gusa gisabwa – guhitamo ibicuruzwa byiza.
