The maqhubu a mefuta e fapaneng ea Radio le Television

Maqhubu Range - nako eo ho pharaletseng sebelisoa ka tsela e ba bafo ba 'meleng botekgeniki, ka ho khetheha ka elektronike. Tlas'a khopolo ena e utloisisa e le bueloang fapaneng ya sesebediswa le ea inehetseng tšebeletso-le-moea ho kgaso ho khetheha e le maqhubu a telele. 'Me re ka bua ka ho sithabela ha kaofela-le-moea maqhubu telele.

melao ea machaba tieo laola tšebeliso ea fapaneng tsamaiso ea-le-moea hasoa (ho akarelletsa le li-satellite), e mengata e fapaneng hantle-hlalosoa. Ena e bitsetsa ke ho hlokahala hore ho etsa bonnete ba tirisano ea litsamaiso fapaneng le ho sebetsa ho felisa tshitiso.

Ho ea ka Radio Melawana, sebaka ea Lefatše e arotsoe setereke tse tharo tse khōlō. Pele se akarelletsa Europe, CIS, Russia, Mongolia le Afrika. Ea bobeli - naheng ea Amerika (bobeli North le South). Ea boraro - South le Asia Boroa-Bochabela, Australia, Pacific sebakeng. Ka e mong le e sebakeng - kabo ea oona ea lihlopha-le-moea maqhubu.

Bakeng sa tšebetso ea sathelaete le puisano e le molao oa tsamaiso e fana ka lihlopha maqhubu le disymbol: L, S, C, X, ku, Ka, K ranges ho tloha 1452 MHz ho 86,0 GHz. Boholo ba batho ba tsamaiso ea sathelaete e sebetsang lihlopha C le ku. Range Ka ntshetswa pele ka mafolofolo ba Europe le Amerika, empa naheng ya rona e sa sebelisoa hohle.

Lenakana bokgoni ke itšetlehile ka palo ea wavelengths hore lumellane le bophara ya manakana ena. Le eketseha maqhubu a, e wavelength e fokotsehile (makgabane tsena ke inversely tekanyo e lekanang ya) le manakana a sa kgolo e sa e hlokehang ho fumana matšoao phahameng maqhubu a. Ho tloha maqhubu a mefuta e fapaneng fumaneng ke manakana a sa boholo ba limithara tse 2.5-4.5, 'me bakeng sa ho fumana lakatsa tsokoang sehlopha K manakana a sa boholo -. Feela 10-15 cm, Ka boholo manakana tšoanang sebetsa ka fapaneng phahameng, na phaello ea phahameng.

Ka e mong le e kgaso seteishene fetisang boetse e na le maqhubu a lona telele. Ho na le ke tlhophiso ea maqhubu-le-moea ka mefuta e fapaneng le wavelength. Ho ea ka e tsokoang ena ke:

- Dekametricheskie le wavelength ea ka taelo ea 10 000-100 000 km, eo maqhubu a li classified e le tlaase ka ho fetisisa (3 - 30 Hz).

- Megametricheskie (wavelength - 000 km 1000-10), e maqhubu a mefuta e fapaneng - 300 Hz.

- Gektokilometrovye (ka e-ba bolelele ea km 100-1,000) tse amanang le maqhubu ultralow (3000 Hz).

- E eketsehileng telele (bolelele - km 10-100) - tlaase haholo (ho fihlela ho 30 kHz).

- bolelele (bolelele ba km 1-10) - tlaase (ho fihlela ho 300 kHz).

- Karolelano (bolelele limithara tse 100-1000) - mids ho 3000 kHz.

- Short, ho ba le e-ba bolelele ba limithara tse 10-100 - ke seo ho thoeng ke .. phahameng maqhubu (maqhubu a 30 MHz).

- Ultrashort kapa mitha (bolelele 1-10 limithara tse), e phahameng haholo (ho fihlela ho 300 MHz).

- Decimeter (bolelele 10-100 cm,) le marang-phahameng, ho fihlela ho 3000 MHz.

- disentimitara (1-10 disentimetara bolelele), bartolomeo-phahameng (ho fihlela ho 30 GHz).

- millimeter (bolelele 1-10 limilimithara), e phahameng haholo (ho fihlela ho 300 GHz).

300-3000 GHz maqhubu a mefuta e fapaneng e bua ka 't. N g. e kholo-phahameng maqhubu telele.

Ka mekhahlelo ea pele ea ntshetsopele ya maqhubu a seea-le-sebediswa hangata telele le bartolomeo-telele telele. Empa ba ile ba ba ho jala fetang holim'a lefatše, e ka matla ananelang, hlokahala mechine e matla. Tsitsitseng baeti ba fihlelang ho e phethahatsoa ka tsokoang mahareng, empa ho bona ho le thata ho etsa bonnete ba phetiso hole, 'me o sebelisa mefuta e fapaneng hona, boholo ba seea-le-ea moo ka radius ea km makholo a' maloa.

Shortwave fana mefuta e fapaneng haholo, empa ke ho ipeha tlas'a lerata le pontšo ho khopama. Di sebediswa haholo-holo moeeng le tsamaya ea likepe e name le amanang ho meleng e ka sehloohong.

Ka ba molemo ho e khōlō ea mekoloko phahameng maqhubu a - monyetla ho sebelisa ka lenakana bao litekanyo tse tšoana le wavelength e, mahlaseli a ke atlehang ka ho feela tlas'a boemo ena. Kaho ea tsamaiso ea mekhoa ea puisano e telele-hole thehiloeng boikatiso ea maqhubu mahlong, e ne e entsoe ka khonehang ka tšebeliso ea maiketsetso satellitari lefatše.
