Niki gihindura icyogajuru nikihe gikora

Ihinduramiterere ya satelite itanga kwakira ibimenyetso bigaragarira hejuru ya antene kandi bigashyikirizwa muburyo bwagutse kuri tereviziyo ya TV. Ubu ni uburyo bugoye burimo amategeko shingiro ya fiziki. Urashobora kugura ibintu nkibi bihinduka ku giciro cyiza.

Ibintu nyamukuru biranga uhindura ni urusaku rwiyongera, rwapimwe muri décibel. Iyo hari urusaku ruto, ishusho kuri TV ntabwo igoreka cyane.

Muri siyanse, uhindura asobanurwa nkuwakira utunganya ibimenyetso bya satelite. Mubyukuri, hari ibikoresho bibiri murwego rumwe rwa monolithic. Igikoresho cya mbere cyongera ibimenyetso byakiriwe na satelite. Aha niho urwego rwurusaku rwinyongera rugira uruhare runini. Ku giciro cyo hasi, hazabaho kutivanga cyane, – 0.3 – 0.5 dB.

Izina LNB cyangwa urusaku ruke naryo rifitanye isano na satelite ihindura.

Igikoresho cya kabiri gihindura imirongo yumurongo. Nubufasha bwabo, ikimenyetso cyoherezwa kubakira cyangwa TV binyuze kure. Offset satelite ni byiza kohereza ibimenyetso. Hano haribisobanuro byibanze byukuntu byose bikora:
Guhindura bituma ibimenyetso byakiriwe bikomera. Ibi bifasha kwishyura ibyangiritse muri kabili ihuza antenne niyakira. Uwakiriye yongeraho urusaku rwarwo ku kimenyetso. Bafite imbaraga zihoraho. Ikimenyetso cya satelite kiva muri antene cyonyine ntigikomeye, bityo kigenda kigabanuka imbere yumugozi, bityo kigomba kongerwa. Nyamara, igikoresho cyinjiza urusaku rwacyo mu kimenyetso, ni ngombwa rero ko ari gito. Ihindura irashobora kugurwa mubirango bitandukanye.

Chipter chip [/ caption] Irradiator ni ubwoko bwa antenne ya kabiri ifata ibimenyetso byoherejwe kuva nyamukuru. Guhindura byongera kandi bigahindura ibimenyetso byumuvuduko mwinshi mubimenyetso byo hasi, urugero, ikimenyetso cya 12000 MHz gihindurwamo inshuro zingana na 1250 MHz. Ikora umurimo wo kwemeza ko ibimenyetso bitagaragaye neza muri kabili. Byiza, ibimenyetso byujuje ubuziranenge mubisobanuro bihanitse byakirwa kuri TV. Ihindura kandi ihindura polarisiyasi. Imiyoboro ntabwo ifite imirongo itandukanye gusa, ahubwo ifite polarizasiyo zitandukanye. Bamwe bahindagurika mu buryo buhagaritse, abandi batambitse. Ni ngombwa uburyo uhindura. Icyerekezo kiratandukanye ahantu hatandukanye ku isi.

Ni ubuhe bwoko bwa satelite ihindura ibiryo bihari

Ihindura, cyane cyane yitwa LNB, irakenewe kugirango uhindure imirongo yumurongo “Ku” (10 … 13 GHz) cyangwa “C” urwego (3.5 … 4.5 GHz) kuri 0.95 … 2.5 GHz, ituma bishoboka ko ibimenyetso byoherezwa hamwe nigihombo gito cyangiritse kugeza kubakira. Ibi bituma bishoboka gukoresha umugozi wa coaxial uhendutse ukayiha uburebure bwa metero 20-30 kugirango ibimenyetso bitazimira. K \ Abahindura bose baratandukanye mumajwi. Ubwinshi bwabo ni bwiza mubundi buryo. Hariho abahindura bakurikira:

1. Guhindura kuri “C”.
2. Guhindura “Ku”.
3. Isi yose “.
