Antenna ea ka tlung bakeng sa thelevishene ea digital: mekhoa ea khetho le mehlala e metle ka ho fetisisa

Ho tloha ka 2019, thelevishene ea Russia e fetohetse ho phatlalatso ea dijithale. Boleng ba setšoantšo bo ntlafala, empa ha bo kenyelle ho hloleha. Ntle le lebokose le letle la sete-top ea dijithale , o tla hloka ho reka antenna e tla thibela mathata. Baahi ba lifolete tsa toropo ba lokela ho khetha antenna ea kahare bakeng sa thelevishene ea dijithale, e kentsoeng ka matlung.

Mefuta ea li-antenna tsa ka tlung bakeng sa TV ea digital

Moamoheli oa lets’oao la TV ka tlung o na le tšobotsi feela eo e kentsoeng ka tlung. Mefuta e fapaneng e na le litekanyetso tse fapaneng tsa matla: ha tekanyo ena e fokotseha, ke moo antenna e lokelang ho behoa TV haufi le eona. Ho na le mefuta e ‘maloa ea li-receptor tsa ka tlung:

1. E sebetsa. Antenna ea ka tlung bakeng sa TV ea digital, e nang le amplifier e khethehileng ea ho amohela lipontšo. E sebelisoa ka likamoreng tse hōle le tora, hammoho le tabeng ea ha letšoao le hloka ho aroloa ka li-TV tse ‘maloa. Molemo ke hore o tsamaisoa ho tloha leboteng la lebota, eseng ho tloha TV – ka hona, antenna e joalo e ka behoa kae kapa kae.
2. Feseha. Antenna e tloaelehileng ntle le amplifier. E na le moralo o khahlehang. E hokela TV ka kotloloho. Bothata ke hore sesebelisoa ha se ikamahanye le boemo ba pontšo, ho fapana le hoo, u tla tlameha ho batla sebaka ka kamoreng moo ho leng molemo, ‘me u kenye TV moo hammoho le antenna.
3. Leqhubu lohle (lebasetere). E amohela maqhubu a khaso ea limithara le li-decimeter, ao, ha ho hlokahala, a ka fetoloang (ho tloha ho e ‘ngoe ho ea ho e’ ngoe).
4. Metara. Lenakana le bonolo ka ho fetisisa le nang le “antennae” bakeng sa ho lokisoa. Moqapi oa bona o bonolo, ‘me letšoao le nkoa feela sebakeng se haufi le tora.
5. Decimeter. E fana ka pontšo e ntle haholo sebakeng sa 30 km.

Mekhoa ea khetho – seo u lokelang ho se sheba ha u khetha antenna ea ka hare bakeng sa “linomoro”

Li-antenna tsa TV tsa ka tlung ha li theko e tlase. Litsenyehelo tsa bona ha li fete li-ruble tse 1000. Boholo ba mehlala e hlahisoa ka mokhoa o thahasellisang oa ka ntle, kahoo ba bang ba atisa ho tsepamisa maikutlo haholo-holo tabeng ena, ‘me feela ka mor’a moo ba nahane ka litšobotsi tsa theknoloji. Ho khetha mohlala o nepahetseng, o hloka ho ela hloko lintlha tse latelang:

1. Bokhoni ba antenna ea ho amohela maqhubu a decimeter (UHF, UHF) ke paramente e ka sehloohong e lokelang ho tsotelloa. Khaso ea dijithale e etsoa hantle ka har’a sebaka sa decimeter.
2. Bokhoni ba ho amohela lets’oao la DVB- T2 . Sena ke sesupo sa maemo ao ho ona thelevishene ea dijithale ea Russia e phatlalatsang.
3. Matla a amplifier . Mokhoa ona o khethoa ho nahanoa ka bohole ba kamore eo antenna e tla leketla ho tloha setsing sa thelevishene. Ha a le hole, moamoheli o lokela ho ba matla le ho feta. Letšoao le fokolang la matla ke 30-40 dB.
4. Motlakase o sa sebetseng kapa o sebetsang . Boemong ba pele, antenna e tla kopanngoa ka ho toba ho TV ‘me e fumane motlakase ho eona. Ke moruo le botle bo botle. Moamoheli oa lets’oao le sebetsang o tsamaisoa ke sokete e arohaneng.
5. Bokhoni ba ho phahamisa maqhubu a FM . Khaso e tloaelehileng ea dijithale e fana ka likanale tse 20 tsa TV le liteishene tse 3 tsa seea-le-moea. Ha se li-antenna tsohle tse khonang ho phahamisa maqhubu a seea-le-moea.
6. Na ho na le amplifier ea matšoao e kenyellelitsoeng ? Karolo ena e tlatselletsang e tla ba molemo ho ba lulang mathōkong a toropo kapa motsaneng, moo matla a pontšo a fokolang.

Mekhoa ea khetho e bonolo, ntho ea bohlokoa ka ho fetisisa ke ho lekola bohole ba folete ea hau ho tloha setsing sa thelevishene.

Li-antenna tsa ka tlung bakeng sa thelevishene ea dijithale: TOP 10 e ntle ka ho fetisisa

Haeba selemong se fetileng TV ea dijithale e ne e le khetho ea boithaopo ea basebelisi ba bang feela, joale ho tloha ka 2019 mmuso o tlamile motho e mong le e mong ho fetohela ho eona ho tloha ho analog e tloaelehileng. Ka hona, potso ea ho khetha li-antenna e bohlokoa ho feta leha e le neng pele. Ke liamoheli life tsa khaso tsa dijithale tsa ka tlung tseo ke lokelang ho li khetha?
