Njengesebe lase-Antenna, i-antenna yezithuthi ineepropathi ezifanayo zokusebenza kwezinye ii-eriyannas, kwaye iya kudibana neengxaki ezifanayo ezinokusetyenziswa.
1. Okokuqala, luyintoni ubudlelwane phakathi kwendawo yokufaka ye-eriyali yemoto kunye nendlela yayo?
Kwithiyori, i-Antenna ifakwe emotweni ayinalo indlela yokuhambisa intetho kwindawo ethe tyaba, kodwa ngenxa yokuma ngokungaqhelekanga komzimba wemoto kunye nofakelo lwe-iriyali eshukumayo, kunye nokusebenza kwe Lo myalelo wahlukile kuleyo ye-eriyali yomgaqo. Uhlobo lwendlela ye-antennas yemoto ayiqhelekanga kwaye iyahluka kwimoto ukuya emotweni.
Ukuba i-eriyali ifakwe embindini wophahla, imitha ye-antenna kwindawo yangaphambili nangasemva iya kuba namandla kancinci kunendlela yasekhohlo nangokufanelekileyo. Ukuba i-eriyali ifakwe kwelinye icala, isiphumo semitha se-radiation singcono kancinci kwelinye icala. Ke ngoko, ngamanye amaxesha sikufumanisa ukuba xa sihamba ngendlela efanayo, isiphumo sokunxibelelana silungile, kodwa xa sibuya, isiphumo sonxibelelwano esingqalileyo kumacala omabini emoto yahlukile.
2. Kutheni le nto imiqondiso yonxibelelwano ngqo kwisicelo se-V / UHF?
Ngokwesiqhelo, i-v / Uhft Amaza ahamba ngeendlela ezininzi ngexesha losulelo, abanye bafikelela kwinqanaba lokufumana kumgca othe ngqo, kwaye abanye bafikelela kwindawo efunyenweyo emva kokucingisisa. Xa i-wave edlulayo kwi-beam yebhedi kwaye ibonakalise amaza kwisigaba esifanayo, ukwahlukana kwamaza amabini avela ekuqiniseni ukomeleza komqondiso. Xa amaza ngokuthe ngqo nangokubonisa ethe ngqo nakwezibonakaliso zikwizigaba ezichaseneyo, isukelwa kwazo ikhupha omnye. Njengomgama phakathi kokudlulisela kunye nokufumana isitishi sikanomathotholo semoto sitshintsha rhoqo xa sishukuma, ubunzulu bamaza erediyo kukutshintsha kakhulu, kubonakaliswa kumqondiso wokulinganisa.
Ngesantya esahlukileyo sokuhambisa, ithuba lokutshintsha kotshintsho lwesaphulelo lwerediyo ukwahlukile. Umgaqo woTshintsho: Ukuphakama rhoqo, okufutshane kwinqanaba eliphakamileyo, ngokukhawuleza ngokukhawuleza, ukuphakama komqondiso wophawu lwalo. Ke ngoko, xa i-disflinusity yomqondiso ichaphazela kakhulu unxibelelwano, unokusinciphisa kancinci isantya, fumana indawo elona phawu lunamandla, yiyeke inqwelo mafutha, kwaye emva koko ubuyele endleleni.
3. Ukufakwa kwe-Antenna faketion okanye ufakelo lwe-oblique lingcono?
Izithuthi ezininzi zisebenzisa i-eriyali ethe nkqo ngezi zizathu zilandelayo: Eyokuqala kukuba i-Aotenation ye-Antenna ingenalo kwicala elithe nkqo, ukuze irediyo yemoto ayinayo i-eriyali ye-eriyali; Okwesibini, i-eriyali ethe nkqo inokusebenzisa iqokobhe lesinyithi njenge-oscillator layo, ukuze xa i-eriyali ethe nkqo isetyenziswa kanye, kwaye kuphela kwesiqingatha semveliso inokufakwa endaweni yemoto yemoto, engabuyisi kuphela Ixabiso, kodwa likwaququzelela ukufakelwa kunye nokusetyenziswa. Okwesithathu kukuba i-eriyali ethe nkqo ithatha indawo encinci, kwaye i-entenna incinci kakhulu, elungele ukushukuma ngokukhawuleza.
Ukusukela kule nto yokujonga, icandelo esilifakileyo liyinxalenye ye-eriyali ethe nkqo. Ke ngoko, xa i-eriyali ifakwe kwicala elinye, amaza erediyo ekhutshwa yi-Antenna ayingasebenzi ngokuthe nkqo, kodwa umxube owenziwe nkqo. Ukuba i-eriyali efumana elinye icala ifumana amaza afakwe nkqo, amandla omqondiso ofunyenweyo (ngokudityaniswa okungaphezulu), kunye ne-vice veredal ye-vie. Ukongeza, i-Antenna ye-oblique iyenza i-radiation engalinganiyo, ebonakaliswa njengemitha phambili ye-eriyali inkulu kune-radiation engasemva, ekhokelela kuqoqosho.
4. Ungasombulula njani ukuphazamiseka kwengxolo ezenziwa yi-eriyali yemoto xa ifumana imiqondiso?
Ukuphazamiseka kwe-Eriyanna Ingxolo ngokubanzi yahlulwe yaza kuphazamiseka kwangaphandle kunye nokuphazamiseka kwangaphakathi iindidi. Ukuphazamiseka kwangaphandle luphawu lokuphazamiseka olufunyenweyo kwi-Antenna ngaphandle kwemoto, njengokuphazamiseka kombane, ukuphazamiseka kombane, enye into yokuphazamiseka kwe-radiation, i-SOPRATIONALS, esona sisombululo sezulu yeyona ndlela ilungileyo yokuhlala kude nomthombo wokuphatha. Ngokwesiqhelo, indlela ye-FM kwi-V / Uhf Band inamandla amakhulu okumelana nolu hlobo lokuphazamiseka. Emva kokuba umqondiso unokuvulwa, umda ongaphakathi wesekethe unokuphelisa ukuphazamiseka. Ukuphazamiseka ngaphakathi, unokuvavanya nje kwaye umamele isikhululo sikanomathotholo esibuthathaka. Ukuba uphazamiso alukhulu, ibonisa ukuba akukho ngxaki ngokuphazamiseka kwenkqubo yezithuthi. Ukuba kukho ezinye iziphazamiso zangaphakathi, usebenzisa ibhodi yokuThunyelwa kweBhodi eya kusombulula uninzi lweengxaki.
IXESHA LOKUQALA: UNV-30 ukuya kwi-2022
