I-antenna yangaphakathi yomabonwakude wedijithali: iindlela zokukhetha kunye neemodeli ezilungileyo

Ukusukela ngo-2019, umabonwakude waseRussia uye watshintshela kusasazo lwedijithali. Umgangatho womfanekiso ubangcono, kodwa awukhupheli ngaphandle ukusilela. Ukongeza kwi- digital set-top box elungileyo, kuya kufuneka uthenge i-eriyali eya kuthintela iingxaki. Abahlali bezindlu zedolophu kufuneka bakhethe i-antenna yangaphakathi kumabonwakude wedijithali, efakwe ngaphakathi.

Iintlobo ze-eriyali zangaphakathi zeTV yedijithali

Umamkeli womqondiso weTV wangaphakathi unikwe kuphela inqaku elixhonywe ngaphakathi. Iimodeli ezahlukeneyo zinemilinganiselo yamandla ahlukeneyo: oku kuphantsi kolu luhlu, ngokusondeleyo i-antenna kufuneka ibekwe kwiTV. Kukho iintlobo ezininzi zezamkeli zesignali zangaphakathi:

1. Iyasebenza. I-eriyali yangaphakathi yeTV yedijithali, ixhotyiswe ngesandisi-lizwi esikhethekileyo sokwamkela. Isetyenziswe kumagumbi abekwe kude nenqaba, kunye nakwimeko xa umqondiso kufuneka uhlukaniswe kwiiTV ezininzi. Inzuzo kukuba inikwe amandla kwi-outlet yodonga, kwaye ingaveli kwiTV – ngoko ke, i-antenna enjalo ingafakwa naphi na.
2. Ungenzi nto. I-eriyali eqhelekileyo ngaphandle kweamplifier. Inoyilo olunomtsalane. Iqhagamshela ngqo kwiTV. Ukungalungi kukuba isixhobo asilungelelanisi kumgangatho wesignali, ngokuchaseneyo, kuya kufuneka ukhangele indawo kwigumbi apho kulunge khona, kwaye ufake iTV apho kunye ne-antenna.
3. I-All-wave (i-hybrid). Yamkela zombini imitha kunye ne-decimeter yamaza osasazo, apho, ukuba kuyimfuneko, inokutshintshwa (ukusuka kwelinye ukuya kwelinye).
4. Imitha. Eyona eriyali ilula ene “eriyali” yohlengahlengiso. Uyilo lwabo lulula, kwaye umqondiso uthathwa kuphela kumgama osondeleyo ukusuka kwinqaba.
5. Idesimitha. Inika umqondiso ogqwesileyo kumgama we-30 km.

Indlela yokukhetha – into omawuyijonge xa ​​ukhetha i-antenna yangaphakathi “yamanani”

Ii-eriyali zikamabonakude zedijithali zangaphakathi azibizi. Iindleko zabo azidluli kwi-ruble ye-1000. Uninzi lweemodeli zinikezelwa kuyilo lwangaphandle olunomdla, ngoko ke abanye bathambekele ekugxininiseni ngokukodwa kule nto, kwaye emva koko baqwalasela iimpawu zobugcisa. Ukukhetha imodeli efanelekileyo, kufuneka ubeke ingqalelo kwezi ndlela zilandelayo:

1. Ikhono le-antenna lokufumana amaza e-decimeter (UHF, UHF) yeyona parameter iphambili ekufuneka ithathelwe ingqalelo. Usasazo lwedijithali lwenziwa ngokuchanekileyo kwi-decimeter range.
2. Ukukwazi ukufumana uphawu lwe-DVB- T2 . Esi sisalathiso somgangatho apho umabonakude waseRashiya wedijithali usasaza khona.
3. Amandla okukhulisa . Lo mgaqo ukhethwe kuthathelwa ingqalelo ukuba kude kwegumbi apho i-eriyali iya kuxhoma kwiziko likamabonakude. Okuya kude, kokukhona unamandla ngakumbi umamkeli kufuneka abe namandla. Ubuncinci besalathisi samandla yi-30-40 dB.
4. Unikezelo lwamandla olwenziwayo okanye olusebenzayo . Kwimeko yokuqala, i-antenna iya kudibaniswa ngokuthe ngqo kwiTV kwaye ifumane umbane kuyo. Inoqoqosho kunye nobuhle. Umamkeli womqondiso osebenzayo unikwa amandla yisokethi eyahlukileyo.
5. Ukukwazi ukuthatha amaza e-FM . Usasazo lwedijithali olusemgangathweni lubonelela ngamajelo e-TV angama-20 kunye nezikhululo zerediyo ezi-3. Ayizizo zonke ii-eriyali ezikwaziyo ukucholachola amaza erediyo.
6. Ingaba sikhona isandisi-lizwi esibandakanyiweyo ? Le nto yokuncedisa iya kuba luncedo kwabo bahlala ngaphandle kwesixeko okanye kwidolophana, apho amandla omqondiso abuthathaka.

Iikhrayitheriya zokukhetha zilula, eyona nto ibalulekileyo kukuvavanya ngokuchanekileyo ukude kwendlu yakho kwiziko likamabonwakude.

Ii-eriyali zangaphakathi zomabonakude wedijithali: I-TOP 10 ingcono
