Offset uye yakananga kutarisisa satellite ndiro: mutsauko uye tuning

Satellite dish ine akati wandei mabhenefiti pamusoro pemamwe antenna maererano nemhando yeiyo inofambiswa ruzha uye mufananidzo. Satellite antennas yakakamurwa kuita offset uye yakananga-yakatarisana (toroidal mukunyorera satellite TV inoshandiswa zvakanyanya kashoma), imwe neimwe ine zvayakanakira nezvayakaipira. Nyaya yacho inotaura nezvekusiyana, kuiswa, kushanda kwemhando idzi dzemahwendefa.

Chii chinonzi offset uye chakananga chinotarisa satellite ndiro

Antennas ane munda wegirazi akakamurwa kuita offset uye yakananga kutarisa. Ose ari maviri magirazi edhishi, asi ane misiyano yakakura. Iyo offset antenna haina kushumirwa zvakanyanya seyechipiri. Kune rimwe zita reyakananga-yakatarisana antennas – axisymmetric, sezvo symmetry yavo yakavakirwa kutenderedza axis imwe. Girazi ravo paraboloid revolution, chimiro chakatenderedzwa, chimiro chinobatsira kuenderana kweiyo geometric axis neiyo yemagetsi. Paaxis imwechete pane shanduko yakasungirirwa kumicheto yereflector ine yakakosha kuvaka. Ngatifungei kutenderera sebhiriji reconvex. Chekutanga chekushandura chinoiswa pane satellite iri pakati. Vashanduri vari padivi vakaiswa zvinoenderana nemufananidzo wegirazi, kureva kuti, kana satellite iri kuruboshwe uye kumusoro, inoshandura inoiswa kurudyi uye pasi peiyo huru. Zvakakosha kuti hapana zvipingamupinyi munzira nenzira yemiti, dzimba refu, nezvimwewo.

Kusarudza nzvimbo yakakodzera yekuisa satellite dish ndiro basa rekutanga

Kuisa satellite dish:

Isu tinoisa madziro akamira pakona ye90 degrees kubva padenga. . Isu tinonamatira zvakasimba nemabhoti uye dowels. Anchor bolts inodzingirwa mumakomba uye yakasungirirwa zvakasimba, nuts dzakamonyoroka, gomo remadziro rinofanira kuiswa, uye nuts dzakasimbiswa pamagumo.

Attention! Zviri nani kuisa chimiro chese cheimba uye wozogadzirisa pamadziro emadziro.

A central converter inoiswa pabracket uye multifeeds inoiswa iyo iyo side converters inosungirirwa. Kutanga, isu tinoisa iyo yakawanda kune yepamusoro satellite (kana iwe wakatarisana neantenna, iri kuruboshwe), zvisungo zvinoiswa paarc, zvinodhonzwa pamwe chete, zvisungo muchimiro chemhete zvinofanirwa kuiswa kune rumwe rutivi. yebhari iyi, chubhu yesimbi inoiswa ipapo, iyo inoshandura inobatwa. A converter inoiswa pane multifeed. Inotenderedzwa ingangoita 100 madhigirii kureba. Rimwe divi rinowanzoenzana nemadhigirii mashanu. Threaded connection – na6 o’clock. Details pamusoro pekuti ungagadzira sei satellite dish .

Attention! Paunenge uchiisa satellite kumabvazuva kwekumaodzanyemba, inoshandura inofanira kuputirwa kune imwe nzira.

Isu tinoisa chechipiri uye chechitatu vashanduri nenzira imwechete, nenhamba diki yemadhigirii. Tinoomesa zvatakaisa. Asi iwe unofanirwa kuzviita pasina kunyanyisa, kuitira kuti urege kuzvipfuudza nenguva yekuedza. Isu tinogadzirira zvidimbu zvitatu zvewaya, tinozvichenesa uye tinozviputira paF-connectors, kuchenesa magumo ewaya mukudzivirira rubber casings, isa zvibatanidza izvi. Kugadzira satellite dish:

1. Pakutanga kwebasa, iwe unofanirwa kuisa iyo huru satellite. Waya kubva kushandurudzo yakabatana nekuisa 1 yeDiSEqC, kubva mukubuda kweDiSEqC switch “Receiver” tambo yakabatana neinopinza yeanogamuchira (tuner) uye michina inotaridzwa kune satellite yatinoda mune imwe. case. Nechinangwa ichi, satellite inogamuchira inoiswa paTV mune inodiwa paramita. Iyo inodiwa frequency inoiswa nemaoko.
2. Kana chiratidzo che “LEVEL + QUALITY” chikaonekwa, unofanirwa kutarisa pa “QUALITY”. Antenna yakamira yakamira inotendeuka kurudyi nekuruboshwe, kana pasina chiratidzo, materu anoshanduka. Kana chiratidzo chakabatwa, tinowana iyo yakanyanya. Tobva tatanga Scanning toona kana takasarudza satellite chaiyo.
3. Isu tinosimbisa makungu ekugadzirisa.
4. Isu tinobatanidza mushanduri kune inodiwa inopinza.
5. Isu tinobatanidza iyo DiSEqC switch.
6. Mune menyu ye satellite inogamuchira mu “Antenna yekumisikidza” modhi, tasarudza iyo inoshandura marongero, isu tinoisa DiSEqC nekuvhura masatellite.
7. Mu “Otomatiki kuseta” modhi, isu tinoongorora ese ma satellite. Tinofanira kutarisa kana vakabatwa. Kana zvese zvakanaka, unogona kuona TV.

Maitiro ekuisa uye kumisikidza yakananga antenna

Nheyo yekuisa yakafanana, asi iyo setup yakasiyana zvishoma. Iwe unofanirwa kutsvaga kukwidziridzwa uye azimuth . Ivo vanogona kuverengerwa ne online calculator. Dzidza menyu, pane chikamu che “Signal level”, iyo inoratidza zvakakosha paramita se “Level” uye “Quality”.
Isu tinounganidza antenna. Pakutanga, zvinyorwa zvinotaridzika seizvi:
Unganidza chiratidziri. Kana pane washers, anofanira kuiswa. Iyo yakasimba dhizaini, zviri nani, iwe unofanirwa kushandisa ese aya hunhu.
Isu tinobatanidza hafu nerubatsiro rwe clamps uye nuts.
Isu tinounganidza chimiro chekutsigira, sunga gumbo ne clamp.
Sarudza fasteners. Zvadaro, unoda kuisa ndiro pagumbo. Zvadaro chimiro chese chinounganidzwa, makumbo ayo akafanana nedandemutande. Iyo pombi yemukati inofanira kubuda pamusoro pemamita maviri. Chiyero pamakumbo, kana chiripo, chakaiswa pane imwe nzvimbo pa 38-40. Kumisikidza yakananga-yakatarisana setiraiti dish kune maviri satellite Yamal (90) + ABC (75): https://youtu.be/4vixVSd_-RY

Operation features

Dzimwe nguva chiratidzo cheantenna hachina kusimba. Ipapo iwe unofanirwa kutarisa kana magirazi eplate akaremara nenzira yekuti inofanana nenhamba yechisere. Izvo zvakakosha kuti, kana iwe ukatarisa kuratidziro kunoenderana nekuvhura, mipendero inobatana kuita mutsara mumwe. Kana iyo inogamuchira isingashande zvakanaka, unoda kutenga imwe itsva. Dzimwe nguva zvinodikanwa kutenga shanduko ine isinganyanyi kukosha ruzha nhamba. Dzimwe nguva unogona kutenga imwe kopi yemujenya wakafanana. Izvo zvakakosha kuti chikafu chekushandura chienderane nef / d yemuratidziri. Unogona kutarisa kureba kweiyo inoshandura inoswedera uye ichienda kure nechiratidziri.

Chokwadi chinofadza. Kaviri pagore, mumatsutso uye muchirimo equinoxes, zuva rinoonekwa richienderana nesatellite uye antenna yekugamuchira. Ipapo mwaranzi yezuva iri mushanduri pamwe chete nesatiraiti chiratidzo. Izvi zvinoderedza kunaka kwechiratidzo. Izvi zvinogona kukanganisa midziyo. Nokudaro, zvakakosha kuisa kadhibhodhi kana polyethylene (opaque) skrini pamberi pe irradiator munguva.

Nzira yekusarudza ndiro yemabasa ako

Antenna imwe neimwe yakanaka nenzira yayo. Offset iri nyore kuisa pamwe nemadziro. Havawani chando nemvura.
Antenna yeparabolic inowanzobatanidzwa nesetiraiti [/ caption] Asi antenna yakananga-yakatarisana ine nzvimbo yemagetsi pane chikafu, isina kubva kumarudzi ese ekukanganiswa, ayo anokanganisa mufananidzo nenzira yakanaka. Offset antenna haina kukanganiswa nekunaya. Ine pakati pesimba rinokwevera zvinhu pasi. Asi antenna yakananga-yakatarisana inoshumirwa pamwero mukuru. Naizvozvo, zviri kuvaridzi kuti vasarudze kuti ndeipi antenna yekusarudza. Kusvika kumwero wakati, zviri nyore kushandisa ndiro yekubvisa, kunyanya sezvo inofarirwa mudzimba dzevanhu. Asi panguva imwecheteyo, ese antennas akanaka munzira yavo. Kana zvichidikanwa, vazhinji vanogona kuchengetedza yakananga-yakatarisana antenna kubva pakunaya. Zvakakwana kuchengetedza inoshandura irradiator pachayo neine visor duku kubva mubhodhoro repurasitiki. Naizvozvo, ese ari maviri akasiyana emaplateti akanaka munzira yavo, zvinodikanwa kuti uenderere mberi kubva kune yega mamiriro.

Mhedziso

Saka, madhishi esatellite, ayo akadzikiswa uye akatarisana akananga, ese ari maviri anonyatso kubata masaini esatellite, uku ndiko kufanana kwavo. Ivo vanosiyana pachinzvimbo uye muchikamu muchimiro cheparaboloid, kureva, iyo antenna yekumisa inomira pakona chaiyo, uye yakananga yekutarisa antenna inowanikwa yakachinjika. Iyo antenna yekumisa inodzivirirwa zvirinani kubva kumarudzi ese emvura, uye ine iri nani nzvimbo yegiravhiti, kunyangwe iyo axisymmetric dish ine isina kuchinjika magineti emagetsi.
