Satellite dish: chii, chii chayo, mhando, sarudzo

Iyo yekutanga uye yakakosha mukana wekushandisa satellite ndiro kugona kuona nhamba huru yematanho mumhando yepamusoro mumakona ari kure kwazvo enyika. Zvakare, zvakanakira kusarudza inodaidzwa kuti dish antenna inosanganisira mukana wekusarudzwa kwakakura kwematanho akasiyana, asi pamhepo kana tambo terevhizheni inotepfenyura chete zvinotariswa neruzhinji rwevaoni.

Chii chinonzi satellite dish uye chinoshanda sei

Setiraiti terevhizheni dish chinhu chakakosha chinoshandiswa kukwanisa kugamuchira zviratidzo zvinobva kusatellite. Nhasi, zvigadzirwa zvakadaro zvinowanzowanikwa muhupenyu hwezuva nezuva, nokuti nerubatsiro rwe satellite dish unogona kutarisa zviteshi zveterevhizheni mune chero kona yenyika. Wese munhu anogona kutenga ndiro ye satellite TV panguva ino, asi chinhu chikuru pano ndechekuita sarudzo yakanaka yechigadzirwa, sezvo ichiuya mumhando dzakasiyana.

Nheyo yekushanda kwesatellite dish uye mudziyo weantenna yekutepfenyura setiraiti terevhizheni

Kugamuchira chiratidzo kubva kune satellite dish kunoitika mumatanho maviri. Kutanga, chiratidzo cheTV chinobatwa uye chakatarisana pane imwe nguva. Muchiitiko ichi, zvinodikanwa kuti ive neamplitude yakakura zvakakwana. Uyezve, chiratidzo chinotanga kukwidziridzwa uye kugadziriswa. Iyo TV ndiro ine zvinhu zviviri zvikuru. Izvi zvinosanganisira converter uye deflector. Yekutanga inoshanda kuratidza uye kutarisisa mwaranzi pane yakakwira frequency, uye yechipiri inoshandura wave wave kuita shanduko yemagetsi inonzwisisika kumidziyo yemumba. Zvimwe zvikamu zvemadhishi esatellite eTV anobatsira. Ndaza yavo inoratidzwa mubhuku remirayiridzo.

offset plates

Offset type satellite ndiro dzine oval deflector. Chiratidziro chakadaro chinoita kuti zvigoneke, zvichienderana nedzimwe nzira, kugamuchira chiratidzo kubva kune maviri kana anopfuura masosi. Zvinoenderana neongororo yevashandisi, tinogona kutaura kuti iyo yakabuda mafungu edhishi rakadaro pasi pemamiriro akafanana yakadzikira pane iyo yemhando dzakatenderedza, nekuti iyo inoratidzira yekuvhara idiki mune oval deflector. Somugumisiro, kuyerera kwechiratidzo chakagamuchirwa kumushanduri zvakare kushoma.

Multifocal

Multi-focus satellite ndiro dzinogashira wave kubva kune akati wandei satellite. Mumidziyo yakadai, inodarika imwe converter inoiswa. Zviratidzo zvinoverengerwa mumwe nomumwe. Dzimwe nguva vanoisa classic deflector uye boka resonant reflectors.

Mesh satellite ndiro

Aya antenna anoita senge magidhi akakomberedzwa, ayo anotsigira uye anoshandura anosungirirwa. Magadzirirwo akadaro anoshanda pamisimboti miviri kamwechete, ichiratidza chiratidzo uye ichichigadzira nekuda kwekuitika kweresonance. Muchokwadi, aya ari kutumira uye kugamuchira satellite ndiro umo wave resonance effect inoshandiswa. Compact modhi dzakakurumbira mukusimudzira simba reiyo wi-fi chiratidzo. Kune zvakare madhizaini anosanganisira madiki anotakurika antenna akaiswa pamutengi uye zviteshi zvepasi zvekugamuchira chiratidzo. Iyi imhando yeT2 nhepfenyuro.

Nzira yekusarudza yakakodzera satellite dish

Zviyero zveantenna zvinogamuchira chiratidzo kubva kune satellite zvinogona kunge zvakasiyana. Broadcast vanoshanda vanopa vashandisi mamiriro akafanana. Vamwe vanopa, senge, semuenzaniso, MTS , shandisa akasiyana antenna zvikamu munzvimbo dzakasiyana.
Zvinoenderana nemusimboti wekushanda kwehurongwa, zviri pachena kuti zviyero zvemadhishi esatellite anoita basa rei. Iyo yakakura iyo inotaridzika pamusoro peiyo deflector, iyo yakawanda wave simba inounganidza uye inotungamira kune inoshandura. Satellite nhepfenyuro nzira dzinowanzoverengerwa zvichienderana neavhareji paramita. Saka, munharaunda yekugamuchira kwakanyanya, mushandisi anogona kuisa chikafu chekare chine dhayamita masendimita makumi matanhatu.

Kusarudza antenna yeInternet

Mushure mekusarudza setiraiti Internet opareta, unofanira kusarudza yakakodzera “ndiro”. Chaizvoizvo, zviri nyore. Kuti uite izvi, haufanirwe kuziva fizikisi kana mafomula, uye hapana chikonzero chekuverenga chero chinhu. Vatengesi vachakwanisa kusarudza antenna yakakodzera nekiti yeInternet satellite.

Kusarudza antenna yeTV

Kana iwe uchida kutenga satellite dish yeTV yako, saka unofanirwa kufunga nezvehukuru hwayo. Iyi parameter yakanangana nekuwana kwechigadzirwa. Iyo yakakura saizi yayo, iyo yakakura iyo parameter yekuwana ichave. Muchiitiko chekuti saizi yedhishi iri pasi peiyo inotenderwa kugamuchira inodiwa transponder, meseji “hapana chiratidzo” ichaonekwa pachiratidziri. Mufananidzo wacho uchaputsika “mumakwere”, uye zvimwechetezvo zvichaitika kana antenna isina kunyatsogadziriswa kune satellite. Kune akasiyana satellite chiratidzo chekugamuchira simba, akasiyana dish madiyamita anodiwa (53 dbW – 0.6 m, 48 dbW – 0.8 m, 45 dbW – 1.0 m, 40 dbW – 1.5 m).

Ndeipi satellite dish iri nani kusarudza yeInternet uye terevhizheni

Offset antennas anonyanya kukodzera kugamuchira satellite TV neInternet. Offset mahwendefa ane asymmetric cutouts kubva paraboloid revolution, umo mune irradiator. Kutariswa kwechinhu ichi kunowanikwa pasi pane geometric centre yeantenna pachayo. Iyi nzvimbo inobvisa mumvuri kubva kune inobatsira pamusoro peiyo antenna feed, pamwe neayo tsigiro. Izvi zvinowedzera iyo inobatsira yekushandisa index ine yakaenzana girazi nzvimbo. Iyo irradiator mumagadzirirwo akadaro inowanikwa yakaderera kupfuura pakati pesimba rendiro. Nokudaro, inowedzera kugadzikana kweantenna mukuputika kwemhepo.

Kusarudza antenna yekupa

Antennas anogashira chiratidzo kubva kune setiraiti, seyawo analogi shanduro, zvinoenderana nesaisai rinouya kubva pasi shongwe. Kana isina simba, saka kutepfenyura kunenge kuri kwehurombo. Nechikonzero ichi, iwe unofanirwa kufunga nezve chinhambwe kune iyo inodzokorora uye kutenga yakakosha amplifiers. Uyewo, usakanganwa nezvemamiriro ekunze. Kuti udzivise zvikanganiso, antenna yekupa inofanira kusarudzwa, ichifunga nezvemitemo inotevera:

• iyo dhizaini inofanirwa kushanda mune yakagamuchirwa frequency renji ye300 – 3000 MHz;
• iyo boom inofanira kuenzana nechekure kune shongwe yepasi;
• zviratidzo zvesimba zvinofanirwa kurongedzwa kuti zvibate masaisai;
• kune nzvimbo yakazaruka kana yesango, zvigadzirwa zvakasiyana-siyana zvinotengwa.

Cherechedza! Kusarudza antenna inoenderana nedhayamita ye deflector iri nyore. Zviri nani kutenga chigadzirwa chine giradhi rinotevera zviyero: kana mushandisi akakurudzira 90 cm, iyo antenna yakaiswa ye 1.2 metres ichapa kugamuchirwa kwakanaka kunyangwe mumamiriro ekunze akaipa.

Nzira yekurembera uye kugadzira satellite dish?

Kuisa satellite dish kumba, iwe uchada zvinotevera maturusi:

• tambo yekuwedzera yezvigadziko zvitatu;
• puncher kana drill nechibooreso chedhayamita inodiwa pakugadzirisa bhuraketi nezvibatiso kana nemadhoiri;
• wrenches 13 mm uye 10 mm muhukuru (zvichida maviri);
• Phillips screwdriver;
• sando;
• adhesive tepi kana zvisungo zvepurasitiki.

Paunounganidza antenna, nyatsosimbisa mabhoti, uye usakanganwa nezve washers. Iwe unofanirwa kupeta 2 multifeeds kune inoshandura inobata . Imwe inoputirwa kurudyi, yechipiri – kuruboshwe pamwe chete nemushanduri. Hazvina kukosha kudhonza zvakanyanya. Izvo zvinoshandawo kune antenna gomo pachayo.
Kushandiswa kwakakurumbira kweakawanda pakuisa satellite dish kune matatu satellite [/ Caption] Iyo bracket inofanirwa kuiswa pamadziro. Tevere, iwe unofanirwa kuturika antenna kuitira kuti inonangana kumaodzanyemba kana kumaodzanyemba kwakadziva kumabvazuva. Mushure meizvozvo, iwe unofanirwa kutambanudza tambo yekuwedzera uye batanidza TV zvakananga kune tuner kana mugamuchiri. Zvose, uku ndiko kuguma kwenyaya. Mukupedzisa, tinogona kutaura kuti mutengo wesatellite ndiro uri kudonha. Nenguva isipi munhu wese achakwanisa kutenga “umbozha” hwakadaro uye tarisa nzira dzakawanda dzekusarudza kubva. Kubva kumutengi chinhu chimwe chete chinodiwa – kusarudza chigadzirwa chakakodzera.
