Bobabili abasakazi bomsakazo we-FM nabanikazi beziteshi zomsakazo banaka kakhulu ukusebenza kwe-antenna yokusakaza ye-FM ngoba inquma ukuthi bangaki ababukeli abangamukela iziteshi zabo zomsakazo.

Uma uhlela ukwakha isiteshi somsakazo we-FM, noma udinga ukuthuthukisa amasignali akho omsakazo we-FM ukuze ukhulise ibhizinisi lakho, noma awenelisekile ngokusebenza kothi lomsakazo we-FM, kungaba ukukhetha okuhle ukufaka esikhundleni I-antenna yokusakaza ye-FM esebenza kangcono. Kepha uyazi ukuthi yini okudingeka uyinake lapho ukhetha i-antenna yomsakazo we-FM?

Njengoba sinolwazi lwamashumi eminyaka ekusakazeni umsakazo we-FM, sizokwethula kafushane i-antenna yomsakazo we-FM futhi sikuchazele amathiphu angu-6 okuthenga i-antenna ehamba phambili yomsakazo we-FM. Masiqhubeke sihlola!

Yini Odinga Ukukwazi Nge-FM Transmitter Antenna?

Ukufunda nje nge-antenna yomsakazo we-FM kungakusiza ukuthi ucacise uhlelo lokuthuthukisa amasiginali omsakazo we-FM ngoba ingenye yemishini ebaluleke kakhulu yokusakaza okulalelwayo ngaphandle kwama-transmitters omsakazo we-FM. Okulandelayo, sizoyifunda ezinhlelweni zayo nokuthi isebenza kanjani.

Izicelo - I-antenna yomsakazo we-FM isetshenziselwa ukusakaza amasignali we-FM aphethe ulwazi oluningi, okuhlanganisa umsindo, izithombe, imibhalo, njll. Ngakho-ke, ithiyo yokusakaza ye-FM ingasetshenziswa kubasakazi bemisakazo, iziteshi zomsakazo ze-FM, njll. Zinobumo nobukhulu obuhlukene. ezinhlelweni ezahlukene zokusakaza. 

Izindlela Zokusebenza - Ohlelweni lokudlulisa i-FM, isidluliseli somsakazo we-FM siguqula amasiginali alalelwayo abe amasiginali omsakazo we-FM, bese kuthi uthi lwesidluliseli se-FM luyawamukela futhi luwasakaze ngendlela yamasignali omsakazo. Ngaphezu kwalokho, uma ufuna ukusakaza amasiginali ezindaweni ezahlukene namabanga, ungawahlanganisa ube amasistimu wezinti ze-FM. 

Sekukonke, ukuthuthukisa amasiginali omsakazo we-FM, ukuqonda okuyisisekelo kwe-antenna yokusakaza ye-FM kuyadingeka, lapho-ke ungacaca ukuthi ungawathuthukisa kanjani amasiginali we-FM.

Amathiphu angu-6 Okuthenga I-Antenna Engcono Kakhulu Yokusakaza I-FM

Akulula ukuqonda ngokugcwele i-antenna yokusakaza ye-FM. Ngenhlanhla, u-FMUSER ufingqa amathiphu angu-6 abaluleke kakhulu okuthenga i-antenna ehamba phambili yomsakazo we-FM. Ngisho noma ungumfundi oqalayo, ungaphumelela kalula.

Qinisekisa Izinhlobo Ezithile

Ukuqinisekisa ukuthi iziphi izinhlobo zothi lokusakaza lwe-FM ozidingayo zingakusiza wonge izindleko futhi ukusebenzise ngokugcwele. Isibonelo, uma udinga ukusakaza edolobheni, kufanele ube ne-antenna eqondisayo enamandla njenge-FM yagi antenna ukunciphisa ukuphazamiseka nokuvinjwa kwamasignali omsakazo we-FM, kuyilapho uma usakaza endaweni yasemaphandleni, ungase udinge i-omnidirectional FM. sakaza i-antenna njenge-FM dipole antenna futhi uzoba nokusakaza okuhle.

Sakaza ngeFrequency Egcwele

I-antenna yokusakaza ye-FM ehambisana nefrikhwensi ye-FM egcwele ingasekela izinsiza zakho zokusakaza kangcono. Isibonelo, uma kukhona amasignali aphazamisayo eduze, udinga ukushintshela kumafrikhwensi okusakaza angasetshenzisiwe. Ngakho-ke, akusona isidluliseli somsakazo we-FM kuphela okufanele sibe nobubanzi obugcwele bemvamisa ye-FM, kodwa futhi ne-antenna yomsakazo we-FM yenza njalo.

Nquma Iphethini Yokudlulisela 

Iphethini ephelele yokudlulisela ihlanganisa indawo yokudlulisela kanye nebanga (eyaziwa nangokuthi inzuzo ye-antenna), futhi kufanele ihambisane nendawo yakho kanye nesidingo sangempela sokudlulisela. Ngokuvamile, uma ufuna ukudlulisa nge-engeli ebanzi, inzuzo ye-antenna izoba ngaphansi, futhi kusho ukuthi i-antenna yakho yokusakaza izomboza ukumboza okuncane. Ngakho-ke, ukunquma iphethini yokudlulisela engcono kakhulu kubaluleke kakhulu, futhi kuyalulekwa ukuthintana nochwepheshe be-FM ukuze uthole usizo.

Khetha i-Polarization Efanelekayo

I-polarization ingaba nomthelela ekuphenduleni kwe-FM eyamukela i-antenna, lokho kusho ukuthi kuzothinta ubunzima bokwamukela isiteshi somsakazo. Izingqinamba zisuka emaphesentini okusetshenziswa kwe-FM ehlukene ethola izimpondo ezinezihlukanisi ezihlukene, futhi i-FM eqondile eyamukela i-antenna inamaphesenti amakhulu kakhulu. Ngakho-ke, ukuze uthole ukufana okuhle kakhulu nabamukeli be-FM, kuyalulekwa ukuthi ukhethe i-antenna yokusakaza ye-FM eqondile.

Qinisekisa Ukufakwa Okulula

I-antenna yomsakazo we-FM efakwa kalula ingaba usizo lapho wakha isiteshi somsakazo we-FM ngezinye izinto ezidingekayo zokusakaza umsakazo futhi unakekela okokusebenza. Akubalulekile kuphela kubaqalayo be-FM kodwa nakochwepheshe be-FM, ngoba akekho ongathanda ukuchitha isikhathi sakhe ekufakeni.

Ihlonyiswe Ngemisebenzi Yokuvikela Ephelele

Imisebenzi yokuvikela ephelele inganweba impilo yesevisi futhi inciphise ukulahlekelwa lapho uthi luhlangabezana nesimo esiyingozi esingafuneki. Njengoba i-antenna yokusakaza ye-FM ivame ukufakwa ngaphandle, kufanele ifakwe imisebenzi yamanzi, i-icing, ukuvikela umswakama.

Lezi ezingenhla zingamathiphu ayi-6 okukhetha i-antenna ehamba phambili yokusakaza ye-FM, futhi sithemba ukuthi kuzosebenza kahle ekwakheni isiteshi somsakazo we-FM nokuheha abalaleli abaningi. Njengomunye wabakhiqizi abahamba phambili be-antenna ye-FM, i-FMUSER ingakunikeza ngezinhlobo ezahlukahlukene zothi lokusakaza lwe-FM ngezidingo ezihlukile zokusakaza ngamanani angcono kakhulu. Uma unentshisekelo kuyo, sicela ukhululeke ukuyihlola!

imibuzo ejwayelekile ukubuzwa

1. Q: Ungabala Kanjani Ubude Be-Antenna Yokusakazwa Kwe-FM?

A: Izinhlobo ezahlukene zezimpondo zomsakazo we-FM zinezindlela ezihlukene zokubala.

Isibonelo, uma udinga ukubala ubude besidlulisi se-FM esiyingxenye yegagasi, uzodinga ifomula: L=v/(2*f), lapho i-v imele isivinini samagagasi ( ~ 3x 10^8 m /sec) kanye no-f umele ifrikhwensi. Futhi uma udinga ukubala ubude bothi lwe-FM dipole, uzodinga ifomula: L=468/f, lapho u-f emele ifrikhwensi.

2. Q: Ungawathuthukisa Kanjani Amasignali Ami Omsakazo We-FM Ngokuphumelelayo?

A: Ukufaka i-antenna yomsakazo we-FM phezulu kuyindlela ephumelela kakhulu yokuthuthukisa amasignali akho omsakazo we-FM.

Sekukonke, kunezindlela ezi-3 zokuthuthukisa amasiginali omsakazo we-FM: Ukufaka i-antenna yomsakazo we-FM phezulu, ukukhetha isidlulisi se-FM esinamandla amakhulu nokukhetha izimpondo ezingcono kakhulu zokusakaza ze-FM. Futhi indlela yokuqala ibiza kancane futhi isebenza kangcono kakhulu.

3. Q: Kwenzekani uma usakaza ngaphandle kothi lwe-FM?

A: Umsakazi we-FM noma idivayisi yomthombo izophulwa.

Izimpawu zomsakazo we-FM nazo ziwuhlobo lwamandla. Uma isidlulisi se-FM sisakaza, sidinga ukususa amandla othini lwe-FM. Uma isidluliseli se-FM singaxhumene nothi lwe-FM, amandla awakwazi ukusuka, futhi isidluliseli se-FM singaphulwa kalula.

4. Q: Yiliphi Ibanga Lefrikhwensi okufanele Lisetshenziswe I-Antenna Yami Yokusakaza I-FM?

A: Kufanele ihlanganise lonke uhla lwefrikhwensi ye-FM, okungukuthi 65.8 MHz - 108.0 MHz.

Ngokuyisisekelo, kunamabhendi ama-3 wefrikhwensi ye-FM:

Ibhendi yokusakaza ye-FM ejwayelekile: 87.5 - 108.0 MHz

Ibhendi yokusakaza yaseJapan FM: 76.0 - 95.0 MHz

Ibhendi ye-OIRT esetshenziswa kakhulu eMpumalanga Yurophu: 65.8 - 74.0 MHz 

Isiphetho

Ukuqonda kalula i-antenna yomsakazo we-FM nokufunda indlela yokukhetha i-antenna ye-FM engcono kakhulu kungaba usizo kuwe ukuthuthukisa ukusebenza komsakazo we-FM, ukukulethela abalaleli abaningi futhi ukhulise ibhizinisi lakho lomsakazo.

Njengomunye wabakhiqizi abahamba phambili be-antenna be-FM, i-FMUSER inikeze izinkulungwane zamakhasimende izimpondo zomsakazo we-FM ezisezingeni eliphezulu emashumini ambalwa eminyaka adlule futhi yahlela uhlelo oluhle kakhulu lwe-antenna ye-FM ukubakhela iziphakamiso.

Uma ufuna okwengeziwe mayelana ne-antenna yomsakazo we-FM noma olunye ulwazi olufanele, sicela ukhululeke ukuxhumana nathi!
