Indlela ukuze usethe i-satellite dish nge kube nomphumela omuhle kakhulu

Ukuze sibhekane umsebenzi, udinga ukwazi ukuthi ukusetha i-satellite dish. Ukuze wenze lokhu, unqume onjani antenna ngeke ukufaka futhi ulungiselele. Basuke offset futhi ebalulekile ngqo. Direct antenna ebalulekile kumele kube inkudlwana ububanzi ngenxa yokuthi Converter kufihla ingxenye lukamakhalekhukhwini. Uma esifundeni sakho iphathelene ukusetshenziswa antenna kanye ububanzi 0.9 noma 1.2 m, bese ukhetha i-antenna offset. Lapho ukumisa i-antenna satellite C-range isetshenziswa C-band Converter, kanye isignali yokubhalisa nokulawula likhombisa izakhiwo imvamisa we 5150 NHz.

antenna ukuma

Ngaphambi kokuba siphendule lo mbuzo, ukuthi ungasetha kanjani i-satellite dish, udinga ukukhetha indawo ukufakwa kwalo. Zonke antenna kumele kuthambekele eningizimu-mpumalanga noma eningizimu-ntshonalanga. Uma ufaka i-odongeni lwendlu kukwenza kungenzeki ukuba eMpumalanga ukuze lapho uthi ogibele ophahleni. On indlela isignali kufanele kube kungela kungenela okukhona ngesimo izakhiwo okusezingeni eliphezulu noma izihlahla.

Kuyi-Internet kukhona itafula equkethe ulwazi orientation we-antenna kuya satellite akhethiwe esenziwa yilanga, ungayisebenzisa ukuze ukhethe satellite, okuyinto ke Orient antenna.

Indlela okufanele uwukhethe nokuthi ukuxhuma isidlo antenna satellite

I-antenna efakwe odongeni, exhunywe ubakaki ekhethekile, okuyinto ke igcina ikhebula antenna wire yokuxhuma Converter futhi isamukeli ezivela kuye. Ikhebula ngokuvamile Ufakwa endlini engela, ukuvimbela umswakama ekutholeni emgodini, okuyinto yena, ivaliwe. Ikhebula akufanele kube isikhathi eside kakhulu, kufanele kube khona ukuxhumana. Lokhu kunciphisa izinga isignali ngocansi kunzima ukuqonda ukuthi kwenzeka kanjani ukuba ulungiselele antenna satellite ukuze ikhwalithi yesithombe kakhulu uma ikhebula okuhambisa isiginali abanelisi.

Ukuqala ukufakwa zenhlangano antenna is elungile C-band Converter e Tuning antenna kwenzeka uma satellite antenna yamal. Yena unesibopho amandla kanye nekhwalithi isignali, futhi ngenxa yalokho, ukuze kahle kanjani isithombe. Converter kungaba ejwayelekile noma ukushintshwa, isib, ezifana "U-Allan '. Converter Kushintshwe angakunikela amandla abanye isignali ngaphezulu.

Setha Converter ukuba antenna

Ngaphambi kokuba siphendule lo mbuzo, indlela ukusetha i-satellite dish, udinga ukufaka Converter, indinganiso noma kuhlanganiswe. Kuhlanganiswe Converter isignali ezingeni kancane lehla, ngakho ububanzi amapuleti kumele kwenyuke. Ukuze usethe i-satellite dish phezu Yamal, kwanele ukusungula Converter C-band evamile, badinga kuphela ukukhumbula ukuthi ukusakaza kuzoqhubeka kule C-band. Esikhathini izindlu Converter has a ilebula ekhombisa ngokusobala ukuthi yiliphi izinga (isici) umsindo zalolu hlobo locingo. Zincane, ngcono ukudluliswa isignali.

Izinga umsindo ku converters ulinganiswa Kelvin. Inani esezingeni le Inkomba - 17 K, okungenani - 13 noma 15k. Ukuze converters ezifana Inkomba inzuzo ngokuvamile inenani 65 dB. Irradiator ngesikhathi antenna iyona element egxile isiginali. It ahluke ngoba offset neqondile antenna eqondile. Udinga nje kuphela ufake irradiator, okuyinto evumelana le-antenna, kungenjalo kukhona nokwehlisa izinga isignali.

depolarization ipuleti ogibele antenna ukuze izikhonkwane waveguides ahlelwe kwenye ohlangothini lwawo. Converter is bese usetha, ezikhethiwe mayelana indawo yayo engela. Zero ukubaluleka ekhonjiswe ngokucacile esikalini kumele ibekwe phezulu. I engela ukuthambekela Converter ukuba zero.

Ukuze uthole okungcono kakhulu isignali izinga, udinga kancane ukuhambisa irradiator, ukubukela ezingeni lakhe. Kungenzeka futhi ukungena futhi Converter, ukuyivala kanjalo isignali yokulandelela. I shift akufanele ukundlula degrees ambalwa uhlangothi noma omunye. Lapho kutholakala kube nomphumela omuhle kakhulu (okungenani u-60% uyogcwala inkomba esikrinini), kungaba bazitshela ukuthi antenna is ubukele.

Ngqo ukubekela satellite dish kanye umamukeli kuthatha isikhathi esiningi. ndima yayo kancane kancane imininingwane imiyalelo ebiyelwe futhi imingcele ethile, kuye ngohlobo antenna, satellite kanye endaweni yakho (isignali Ukusabalala).
