Satellite dish. Ntoni na kwaye nokuba ingaba kuyimfuneko ukwenza antenna ekhaya

Iinzuzo elifika umnini wayo isidlo satellite, iye yakhokelela ukuthandwa TV yesathelayithi. Eneneni, enkosi ukhetho ebanzi lamajelo awukwazi nje ukufumana imvume yokungena kwi inani enkulu bhanya, lezemidlalo olithandayo kunye neenkqubo zenkcubeko, kodwa ukuze zihlale zinolwazi ngazo zonke iziganeko ezibalulekileyo, ukuba nsinya ulwazi lwabo ulwimi lwasemzini, oko kukuthi, ukudibanisa yokuzonwabisa olumnandi, kunye imfundo-self luncedo. Ukuba ufaka umfanekiso incamisileyo nomgangatho ephilileyo, kucacile ukuba kutheni isidlo nezesathelayithi umdla kangaka abo kanye lubonisa oko umabonwakude kwi kwigumbi omtsha okanye Sikruqukile uphazamiseko rhoqo kwi uphawu ulwamkelo.

njani isidlo satellite?

Umgaqo kakhulu intsebenziswano yazo zonke izitya imalunga efanayo. uphawu lokuqala iwela isipili kumphezulu satellite eriyali. Yena ngoko kubhalwe kwaye wathumela lokuguqulela, apho, yena, uya receiver, kunye nayo iya ngqo kwi umabonwakude ngokwalo.

Esityeni satellite isenokuba yenye iintlobo ezimbini: focal ngqo okanye offset. eriyali Offset akukho mayibhekiswe ngqo ukuya satellite, yaye ngezantsi nje njengokuba uphawu ukuba iboniswa ukusuka kumphezulu wayo, ungena Converter kwi engile ethile. Olu hlobo lokufumana isixhobo Iqinisekile phantse nkqo, ngaloo ndlela sikuphephe nokwanda ye kwezulu, eya isiba mandundu kakhulu umgangatho ulwamkelo. Kwaba njalo i-eriyali enjalo kubonakala iifestile izakhiwo zokuhlala, ekubeni lula ukufaka ecaleni iindonga. Ubukhulu kangangoko amacwecwe ngu 1.5-1.8 m.

In ngqo focal isipili umphezulu inxalenye isixhobo ivale lokuguqulela, kodwa ukwandisa idiagonal kuba zokuqhubela. Umgangatho yokwamkela kuxhomekeke kubungakanani. iimpawu Good ukuqala 1,5 m. ezinjalo dimensions iipleyiti irradiator kuphinda "izithunzi" kumphezulu esipilini. Olu hlobo thwanga esetyenziselwa ukufumana umsebenzi.

Kufuneka kuqatshelwe ukuba esityeni nezesathelayithi kakhulu "ukhetho 'ukuya kummandla. Naluphi na uphazamiseko endleleni umqondiso, nokuba umthi okanye udonga, ukuze ngokupheleleyo okanye inxalenye 'ukuba amanqaku ulwamkelo. " Ngoko ke, ngaphambi kokuba uthenge kunokwenzeka kuyimfuneko ukukhangela ukuba ngaba kukho uphazamiseko kwi kwicala ufakelo indawo ekujongwe ukuba satellite ekhethiweyo.

Satellite esityeni ngezandla zabo. Ingaba kubalulekile ukuzama?

Xa uchwetheza ekufuneni Google «ekhaya-ezenziwe maza", i-Internet iza kunika imifanekiso kakhulu engaqhelekanga imifanekiso noyilo emangalisayo yokuba ngamanye amaxesha owathandayo ukuyila olukhulu woMntu. Apha neetoti utywala, yamaHindu, kunye iiplanga steel wire and cut kwalenza amaphepha , njl nayiphi na oku kuya kusebenza? Mhlawumbi. Kodwa akubonakali isakhiwo enjalo kuthelekiswa ipleyiti eqhelekileyo, nabanako ngokulula zingathengwa kuyo nayiphi na ivenkile elithile. Ngenxa yokuba ixabiso avareji maza kakhulu lwentando yesininzi, akukho mfuneko ukuchitha ixesha ekwakhiweni zokwakha ethandabuzekayo, ngaphandle, mhlawumbi, ityala ukuba umntu yinto umenzi ngemvelo okanye onolwazi olunzulu kule ndawo.
