I-antenna yesiteshi somsakazo we-FM ingenye yemishini yokudlulisela ebaluleke kakhulu nebiza kakhulu esiteshini sakho somsakazo we-FM. Ingakongela isikhathi esiningi nomzamo kanye nezindleko zokuyilungisa uma ungakhetha i-antenna eqinile yokusakaza ye-FM esebenza kahle.

Kubaluleke kakhulu, ikakhulukazi kwabaqalayo be-RF. Kodwa-ke, badinga umhlahlandlela wokuthenga ukuze ubasize bahlunge imininingwane ebaluleke kakhulu yokuthenga mayelana ne-antenna yokusakaza ye-FM. 

Ngenhlanhla, sizokunikeza amathiphu angu-6 abaluleke kakhulu okuthenga ongawaqaphela, ukukusiza ukuthi uthenge i-antenna yesiteshi somsakazo we-FM ngamanani angcono kakhulu. Ake siqale!

izinhlobo

Udinga ukukhetha uhlobo olungcono kakhulu lwezimpondo zokusakaza ze-FM ezinezici ezihlukene ngokusekelwe ezinhlelweni zokusebenza ezahlukene. Ngokuvamile, ama-antenna omsakazo we-FM afika ngalezi zinhlobo ezilandelayo ezijwayelekile:

• I-antenna ye-Monopole FM - Isebenza kangcono kububanzi obuncane futhi ingagoqeka. Imvamisa isetshenziswa kuma-transmitter omsakazo we-FM enamandla aphansi nasezimotweni.

• I-antenna ye-Dipole FM - Kungenye yezinhlobo ezaziwa kakhulu ezisetshenziswa ezintini zesiteshi somsakazo we-FM. Inebhendi yefrikhwensi ebanzi futhi ingakhazimula kuzo zonke izinhlangothi.

• I-antenna ye-Yagi FM - I-antenna ye-Yagi iwuhlobo lwe-antenna yenzuzo ephezulu. Ilungele izinhlelo zokusebenza ezidinga ukudluliswa kwamasignali omsakazo webanga elide, njenge-Studio Transmitter Link edinga ukudlulisa indlela ende.

• I-antenna ene-polarized - Ivumela kokubili ama-antenna atholayo aqondile noma avundlile ukuze akwazi ukwamukela amasignali omsakazo.

Ukuqondiswa

Yiqiniso, ukuqondisa kubaluleke kakhulu. Udinga ukucaca ngenjongo yomsakazo wakho we-FM.

Uma ufuna ukudlulisa izinhlelo zakho zokusakaza emsakazweni ezilalelini ezizungezile, lapho-ke cishe udinga i-antenna ye-omnidirectional, efana ne-dipole FM antenna, noma inhlanganisela yezimpondo ezimbalwa zokusakaza ze-FM zihlangene.

Futhi uma isiteshi sakho somsakazo i-FM sisetshenziselwa ukudlulisa amasignali omsakazo ohlangothini olulodwa njenge-Studio Transmitter Link, ngakho-ke akungabazeki ukuthi udinga i-antenna yesiteshi somsakazo we-FM eqondisayo, njengothi lwe-Yagi FM.

Thola

Ukuzuza okuphezulu kusho ukuthi i-antenna yakho yokusakaza ye-FM igxilisa isignali yomsakazo endaweni elinganiselwe, okuholela emandleni esignali yomsakazo anamandla. Kusho futhi ukuthi inzuzo nokuqondisa kuhlobene, futhi inzuzo ekhulayo ingase idele uhla oluthile lwemisebe.

Ziningi izindlela zokuthuthukisa ukuzuza, njengokwandisa inani lezimpondo zesiteshi somsakazo we-FM noma ukufaka izimpondo zomsakazo we-FM ngenzuzo ephezulu. Kuya ezicini zamasiginali omsakazo owudingayo.

Komkhawulokudonsa

Mayelana nomkhawulokudonsa, kunezinhlobo ezimbili zezinti: i-wide band FM antenna kanye ne-FM eshuniwe.

Ama-antenna ebhendi ebanzi ye-FM anomkhawulokudonsa ongaguquki ongaba ngu-20MHz futhi asebenza kahle kuwo wonke ama-20MHz ebhendi ye-FM. Futhi ingasebenza kahle ku-bandwidth.

Ama-antenna e-FM ashuniwe ashintshwa kuphela ebhendini elincane elizungeze imvamisa ebishunwe ngayo. Futhi ayikwazi ukusebenza ngokugcina ukusebenza okufanayo kumkhawulokudonsa.

Ama-antenna e-Broadband FM ahlala encamela kunalawo ashuniwe ngisho noma ebiza ngaphezulu.

I-Polarization

I-polarization ibhekisela ekuqondeni kwenkundla ye-electromagnetic ekhiqizwe i-antenna yesiteshi somsakazo we-FM, futhi ihlukaniswe nge-polarization eqondile nevundlile. Indlela ye-polarization ye-antenna eyamukelayo kanye nothi oludluliselayo kufanele kuhambisane ukuze kube nomthelela omuhle wokuxhumana. Ngakho-ke, ukukhetha kwe-polarization kuncike esimweni sendawo.

Uma ungaqiniseki ukuthi iyiphi i-polarization engcono kakhulu, ungakhetha i-antenna eyindilinga ene-polarization, ene-polarization eqondile kanye ne-polarization evundlile, kodwa umphumela wokwamukela ngothi olwamukelayo uzoncipha ngohhafu, ngoba amandla esignali yomsakazo azohlukaniswa ngokulinganayo. ezinhlangothini ezimbili.

Abakhiqizi

Umkhiqizo ongcono kakhulu ungaqinisekisa ikhwalithi ephezulu yemikhiqizo yabo, njenge-FMUSER, futhi hhayi lokho kuphela, ungathola nezinsizakalo zabo zekhwalithi nemikhiqizo ngentengo egculisayo, wehlise ukuthenga kwakho nezinye izindleko futhi ikuvumela ukuthi ugxile kakhulu Umsebenzi wesiteshi somsakazo we-FM.

Isiphetho

Ake sifingqe indlela yokukhetha i-antenna engcono kakhulu yesiteshi somsakazo we-FM:

• izinhlobo - Khetha izinhlobo ezahlukene ze-antenna ezisakazwa nge-FM ngokuya ngesimo sohlelo lokusebenza
• Ukuqondiswa - Kuncike enjongweni yokudluliselwa kwesignali.
• Thola - Kuya ezicini zamasignali omsakazo ozifunayo.
• Komkhawulokudonsa - Ububanzi bungcono, ngangokunokwenzeka ngesignali ye-FM.
• I-Polarization - Qiniseka ukuthi imisakazo ingazithola kahle izinhlelo zakho zokusakaza.

Ngokusekelwe kulawa macebiso ayi-6 okuthenga, ngisho noma ungumuntu osaqalayo we-RF, ungathola i-antenna yesiteshi somsakazo we-FM ehamba phambili, futhi uthuthukise amasiginali wesiteshi somsakazo abe ngcono kakhulu.

Uma ufuna ukwazi okwengeziwe ngama-antenna esiteshi somsakazo we-FM, sicela ukhululeke ukuxhumana ne-FMUSER!
