Kureka no kuyobora ibyokurya bya satelite: itandukaniro no guhuza

Ibyokurya bya satelite bifite inyungu nyinshi kurenza izindi antene ukurikije ubwiza bwijwi ryanduye hamwe nishusho. Antenne ya satelite igabanijwemo offset no kwibanda-kuri (toroidal muri televiziyo ya televiziyo ikoresha abayikoresha gake cyane), buri kimwe gifite ibyiza byacyo. Ingingo ivuga itandukaniro, kwishyiriraho, imikorere yubwoko bwa plaque.

Niki offset kandi yibanze yibikoresho bya satelite

Antenna hamwe nindorerwamo umurima igabanijwemo offset no kwibanda kumurongo. Byombi ni indorerwamo za parabolike, ariko zifite itandukaniro rikomeye. Antenna ya offset ntabwo ikoreshwa cyane nkiya kabiri. Hariho irindi zina rya antenne itaziguye – axisymmetric, kuva impuzamikorere yabo yubatswe hafi yumurongo umwe. Indorerwamo yabo ni paraboloide ya revolution, imiterere irazengurutse, imiterere igira uruhare mu guhura kwa geometrike hamwe nu mashanyarazi. Ku murongo umwe hariho impinduka ifatanye kumpera yumucyo hamwe nubwubatsi budasanzwe. [ibisobanuro id = “umugereka_3559” align = “aligncenter” ubugari = “400”]
Ibyokurya-byibanze byibanze [/ caption] Antenna ya offset isa nkaho yaciwe muri parabola. Ubusanzwe paraboloide ihuza na silinderi. Ishoka yabo ihora ikora iringaniye. Indorerwamo ya antenne ifite imiterere ya elliptique, kandi umurongo w’amashanyarazi utandukana n’inguni runaka uhereye kuri geometrike.

Offset antenne [/ caption] Antenne zombi zifite ibyiza nibibi. Antenna itaziguye-yemerera gukoresha neza indorerwamo. Antenna ya offset ifite imiterere itandukanye gato. Kugirango ubone ahantu heza, umuntu agomba kugwiza umubiri na cosine yinguni hagati yamashoka abiri: amashanyarazi na geometrike. Ariko hamwe na antenne yibanze, igice kinini cyubuso gitwikiriwe nuhindura hamwe numusozi uherekeza, udakoreshwa mubundi bwoko bwa antene. Kubwibyo, antenne yibanze yibanze ni nini cyane. Muri antenne ya axisymmetric, izamurwa muburyo bwiza, imvura irundanya. Antenne ya Offset yashyizweho hafi ihagaritse cyangwa ihanamye, kandi ntabwo yegeranya imvura ubwayo. Ariko, kubera ko uhindura areba hejuru, bigomba gukorwa mu kirere, kugira ngo amazi atinjira. Iyindi nyungu ya antenne ya offset nuko centre yububasha yose yimurwa hasi bitewe na bracket na transformateur, byongerera uburemere hepfo. Antenna yibanze murugo:

Nigute ushobora gushiraho no gushiraho antenne ya offset

Offset antenne ifite icyerekezo cyahinduwe kuko icyerekezo ni oval. Iyi antenne ni nshyashya, iragufasha gushyiramo kabiri ndetse niyo ya gatatu ihindura, yakira byinshi binyuze kuri satelite, ukurikije aho biri. .

Ikintu gishimishije. Kabiri mu mwaka, mugihe cyizuba nimpeshyi, izuba rigaragara rijyanye na satelite na antene yakira. Noneho imirasire yizuba iri mubihinduranya hamwe nikimenyetso cya satelite. Ibi bitesha agaciro ubwiza bwibimenyetso. Ibi birashobora kwangiza ibikoresho. Niyo mpamvu, birakenewe gushyira ikarito cyangwa polyethylene (opaque) imbere ya irradiator mugihe.

Nigute ushobora guhitamo isahani kubikorwa byawe

Buri antenne ni nziza muburyo bwayo. Offset iroroshye gushira kurukuta. Ntibabona urubura n’imvura. [ibisobanuro id = “umugereka_3294” align = “aligncenter” ubugari = “617”]
Antenna ya parabolike ikunze guhuzwa na satelite [/ caption] Ariko antenne yibanze-yibanda kuri electromagnetique yibiribwa, bitarimo kugoreka ubwoko bwose, bigira ingaruka kumashusho muburyo bwiza. Offset antenna ntabwo ihindurwa nimvura. Ifite hagati ya rukuruzi rukuruzi hepfo. Ariko antenne itaziguye yibanze itangwa murwego runini. Kubwibyo, ba nyirubwite ni bo bahitamo antenne yo guhitamo. Ku rugero runaka, biroroshye cyane gukoresha isahani ya offset, cyane ko ikunzwe mumazu yigenga. Ariko icyarimwe, antene zombi ninziza muburyo bwabo. Niba ubyifuza, benshi bashoboye kurinda antenne itaziguye kugirango imvura igwe. Birahagije kurinda irradiator ihindura ubwayo hamwe na visor ntoya kumacupa ya plastike. Kubwibyo, ibice byombi byamasahani nibyiza muburyo bwabo, birakenewe ko umuntu ava mubintu byihariye.

Umwanzuro

Noneho, ibyokurya bya satelite, byuzuye kandi byibanze, byombi bifata neza ibimenyetso bya satelite, ibi birasa. Baratandukanye mumwanya kandi igice muburyo bwa paraboloide, aribyo, antenne ya offset ihagaze kumurongo wiburyo, kandi antenne yibanze yibanze ihanamye. Antenna ya offset irinzwe neza nubwoko bwose bwimvura, kandi ifite centre nziza yububasha, nubwo isahani ya axisymmetric ifite ikibanza kitagabanije amashanyarazi.
