Kutheni ufuna i-antenna amplifier

Umgangatho womboniso wamabonwakude owamukelwe kuxhomekeke kwiimeko ezininzi. Lo ngumda kumthombo we-TV ukusasazwa, kunye neempawu zendawo yeenxa zonke, ngokukodwa, ubukho bezinto ezikwazi ukudala ukuphazamiseka kwe-electromagnetic kwinqanaba lomqondiso. I-antenna amplifier inceda ukukhusela iimpazamo ezinokwenzeka kwimifanekiso kwezinye iimeko.

Esi sixhobo esiyingqayizivele siya kwenza umgangatho wakho omsindo, kwaye umfanekiso ucoceke. Nangona imeko yemozulu ayilona nto ibaluleke kakhulu, kwaye umgama kwinqanaba le-TV likhulu.

Abakhiqizi banamhlanje banikela abathengi nge-TV ye-antenna amplifier, eyenzelwe ukuba isebenze kwiimeko ezihambelana neemeko ezibi kakhulu. Ezi ndlela zibonelelwa ngokukhuseliswa okongeziweyo ngokuchithwa kwe-electromagnetic, kwaye ukugqoka okukhuselekileyo kusetyenziswa kumzimba wabo (umzekelo, iTrara MA 024, i-ACV Style, i-Alcad AL 200).

Xa ukhetha i-amplifier ye-antenna yeTV, kufuneka ufunde ngokucophelela iimpawu zayo zobugcisa. Uninzi lwabo lujoliswe ngokukodwa kumandla kwesi sixhobo. Oku, mhlawumbi, ngumgaqo-siseko, ukuvumela ukuba ukhethe okokulo okanye lo mzekelo. Ngelo xesha, kuyimfuneko ukuqwalasela iiparameters zegumbi apho i-amplifier ye-antenna ifakwe. Kufuneka kuqatshelwe ukuba le fowuni ayivumeli kuphela ukukhulisa isignali engenayo, kodwa kwakhona ukwahlula ibe ngabamkeli abaninzi. Ngenxa yale njongo, ezi zixhobo zixhotyiswe ngeziphumo eziliqela, ezivumela uxhumano olulodwa lwababamkeli bamabonwakude ngaphakathi kwelinye igumbi.

Xa ukhethe imodeli ethile, qhagamshelana neengcali malunga nokuhambelana kwayo kunye nomgangatho we-antenna efakwe kunye nomkhwa we-receiver yakho ye-TV. Mhlawumbi iimpembelelo ezidibeneyo kumgangatho wesigatshulwa esifumeneyo "ziya kubangela" yonke imizamo yakho. Ngokukodwa ukuba ukulungelelaniswa okungalunganga komxhasi kunye ne-antenna yenziwe. Kule meko, izibhamu aziyi kuvela kwiimifanekiso ezifumanayo. Kodwa abanye abakhiqizi bathi ibomvuli ye-antenna yanamhlanje iyahambelana nayo yonke imveliso eyaziwayo yeTV.

Amacebo amaninzi afakwe izilawuli ezizodwa ezakhelwe ngaphakathi, apho kunokwenzeka ukulawula ngokwahlukileyo inzuzo yesignali engenayo. Kule meko, uhlengahlengiso lwenziwe kwinqanaba elingadluli kwi-15 dB.

Ukuze usebenze ngokukhuselekileyo kwezi zixhobo, ininzi imodeli ifakwe kwisalathisi esikhethekileyo sokuvelisa iindawo ezihlala kwizindlu kunye neqhagamshana lokuqhagamshelana evumela uxhumano lwezindlu ukuya emhlabathini.

I-Antenna amplifier ingaba neenguqu ezininzi zokuyila. Ifowuni yangaphandle ifakwa ngqo kwi-mast ngaphandle kwegumbi kufuphi ne-antenna. Le yiyo ebizwa ngokuba ngumgcini wesikhuni. Udidi lwesibini lufakwe kufuphi neTV ngaphakathi kwendlu. Le yindawo yokukhulisa indlu. Uhlobo lokuqala ukusuka kwindawo yokuphakanyiswa kwesignali lukhethwayo. Ngokukodwa kwimeko apho kukho ukufumana umgama omde. Ukuze ugweme ukubola, iintambo zekhoaxial zanamuhla ziyasetyenziswa . Kwezinye iimeko, iindlela zokwenza umtsalane zakhiwa.

Ukufakela kwimimandla yasemaphandleni, kulungele ukusebenzisa ifowuni ngenzuzo yokufumana ama-decibel angamashumi amane ukuya kumahlanu.

Naliphi na ikhethi ozikhethela yona, makungqinisise umgangatho kunye nokuthembeka okubhengezwe ngumenzi, umfanekiso onommkeli wakho weTV uza kuhlala ucacile, kunye nesandi somgangatho ophezulu. Akusiyo into yokuba imfuneko yalezi zixhobo ikhula unyaka ngamnye, njengoko wonke umntu ufuna ukubuka iinkqubo ezizithandayo ngaphandle kokuphazamiseka kunye nesandi esingenakuphazamiseka.
