Yini eyenza Irediyo Ikhwalithi Engcono Kakhulu?

Empeleni, umbuzo onzima futhi onzima kangaka ukuwuphendula ngoba ziningi izinto ezizothinta ikhwalithi yesignali yomsakazo we-FM. Isibonelo, akuwona kuphela amandla okudlulisela omsakazo we-FM azothinta amasignali, kodwa nezinye izici ezivamile njengokuphakama kothi lwe-FM, isimo sezulu, njll. 

Lapha sizobonisa uhlu lwezinto ezi-5 ezibaluleke kakhulu zokubhekisela:

• Ukuzuza kwe-antenna ye-FM - Uthi lwe-FM oluqondisayo lungagxilisa ingqondo futhi ludlulisele amasignali omsakazo ohlangothini olulodwa. Ukuzuza okuphezulu, amasiginali omsakazo we-FM angasakaza kude ngendlela ethile. 

• Amandla okudlulisa we-transmitter - Amandla omsakazo we-FM nawo athinta ibanga lokudluliswa kwamasignali omsakazo. Amandla aphezulu, ibanga elide amasignali angalihamba.

• Ubude bokufakwa kwe-antenna - Ukuphakama kothi kungenye yezinto ezinquma ukusabalala kwamasignali omsakazo. Lapho i-antenna ye-FM ifakiwe, kulapho amasignali omsakazo we-FM angasakaza khona.

• Ubude bomqhubi wothi lwe-FM - Ubude bomqhubi we-antenna ye-FM buthinta i-VSWR yomsakazo we-FM. Ubude bayo kufanele bulungiswe bube bungcono kakhulu ukuze kugwenywe ukulahleka kwamandla.

• Izithiyo ezizungeze indawo yokudlulisela - Njengoba amasiginali we-FM enamandla abuthakathaka uma engena ezithiyo, izithiyo ezimbalwa ezizungeze indawo yokudlulisela, kulapho amasignali angasakazwa khona.

Nawa amaphakheji we-FMUSER FM dipole antennas, angakusiza uthuthukise amasiginali we-FM ngempumelelo. 

I-FMUSER I-Transmitter Antennas Ethengiswa Kakhulu - Okuningi

Ingabe Uyafuna Ukuthuthukisa Amasignali Akho? Nakhu Okudingayo

Amathiphu 1 - Khetha i-FM enenzuzo ephezulu

Lapho inzuzo yothi lwe-FM yakho iphezulu, isignali yakho yomsakazo we-FM izoqina, futhi ikwazi ukudlulisela phambili ibheke endaweni ethile. 

Uma udinga ukuthuthukisa isignali yomsakazo ohlangothini oluthile, bese ukhetha uthi oludlulisa i-FM oluzuza kakhulu esiteshini sakho somsakazo. 

Uma udinga ukuthuthukisa amasignali omsakazo we-FM kuzo zonke izinhlangothi, udinga izihlukanisi kanye nezimpondo ezimbalwa eziqondisayo ezidlulisa amasignali omsakazo we-FM ezindaweni ezahlukene.

Amathiphu 2 - Thola Indawo Engcono Kakhulu Ye-Transmitting Tower

Kufanele ukhethe indawo enezithiyo ezimbalwa lapho ufaka umbhoshongo wokudlulisa. Njengoba isignali ye-FM ingeyebanga le-VHF ku-spectrum yomsakazo, ibonakala ngamaza amaza amafushane, ngakho inamandla okungena abuthaka.

Uma kunezakhiwo, izihlahla, nezinye izithiyo ezizungeze, kuzonciphisa kakhulu ukusabalala kwamasignali omsakazo we-FM. 

Ngakho-ke, sincoma ukuthi wakhe umbhoshongo wokudlulisela endaweni enezithiyo ezimbalwa ezizungezile, njengendawo yasemaphandleni ekude nedolobha, njll.

Amathiphu 3 - Faka i-Antenna Phezulu

Eziteshini zomsakazo we-FM, indawo yokufaka uthi lwe-FM idinga ukuba phezulu ngangokunokwenzeka. 

Njengoba amasiginali omsakazo we-FM asakazeka ngendlela yokukhomba-ephuzwini, kucatshangwa ukuthi i-antenna ye-FM inamehlo, ibanga eliphakeme elingasakaza likhawulelwe umkhathizwe obonakalayo. 

Cabanga ukuthi, lapho uphakama, yilapho ungabona ukude, akunjalo? Lokhu kuyiqiniso nangezimpawu zomsakazo we-FM. Lapho i-antenna ye-FM ifakwa phezulu, kulapho amasignali omsakazo we-FM angasakazwa khona.

Amathiphu 4 - Lungisa Ubude Bekhondisi Ye-Antenna Buye Kuhle kakhulu

I-FM Dipole antennas ingezinye zezimpondo ezisetshenziswa kakhulu ekusakazeni umsakazo we-FM. Uma usebenzisa i-FM dipole antenna, udinga ukukala ubude bomqhubi we-antenna. 

Ubude be-antenna bungabalwa ngale fomula: L=234/F. U-L ubhekisela kubude bekhondatha ye-antenna ezinyaweni. U-F umele i-frequency ku-MHz. 

Njengoba ubude be-antenna buzothinta i-VSWR yesidlulisi somsakazo we-FM. Ukukhuphuka kwe-VSWR kusho ukuthi amandla amancane asetshenziswa ukusakaza isignali yomsakazo we-FM, okuholela ekutheni isignali yomsakazo ingakwazi ukuhamba ibanga elide ngangokunokwenzeka.

Amathiphu 5 - Khetha I-FM Radio Transmitter enamandla Aphezulu

Uma uke wazama lawa macebiso angenhla kodwa awasizi ekukusizeni uthuthukise ikhwalithi yesiginali yomsakazo wakho we-FM, kungenzeka ukuthi isiteshi sakho somsakazo we-FM asinawo amandla anele okusakaza isignali yomsakazo we-FM iye kude. 

Ungashintsha isidlulisi somsakazo we-FM ufake leso esinamandla engeziwe okusakaza isignali yomsakazo kude futhi uthuthukise ikhwalithi yesignali yomsakazo.

imibuzo ejwayelekile ukubuzwa

1. Q: Iluphi I-Antenna Yokusakaza Ye-FM Esetshenziswa Kakhulu?

A: Kufanele kube i-dipole antenna ye-FM.

Njengolunye lwezinhlobo ezibaluleke kakhulu zezimpondo ze-FM, i-FM dipole antenna iyona esetshenziswa kakhulu. Ngenxa yezindleko zayo eziphansi nokwakhiwa okulula, yazuza abaningi abathandwayo emhlabeni wonke.

2. Q: Ungabala Kanjani Ubude Be-FM Dipole Antenna?

A: Udinga ukubala ngefomula: L=468/F.

Ubude be-antenna ye-FM buncike kumaza okusebenza. Ubude bomqhubi bungabalwa kusetshenziswa le fomula: L = 468 / F. L ubude bothi, ezinyaweni. F imvamisa edingekayo, ngo-MHz.

3. Q: Ungalukhetha Kanjani I-Antenna Yokusakaza Ye-FM Engcono Kakhulu?

A: Kufanele ucabangele izidingo zakho zokusakaza: Amandla okudlulisa, i-Polarization, Inzuzo, izici zomzimba, njll.

Ngaphambi kokuthenga i-antenna engcono kakhulu yokusakaza ye-FM, udinga ukucabangela izidingo zakho. Ngoba i-antenna ehlukene yokusakaza ye-FM inezici ezihlukene, okuhlanganisa amandla aphezulu okudlulisa, ukuhlukaniswa kwe-polarization, nephethini, inzuzo, umthwalo komoya, njll. Inquma ukuthi yiluphi uthi okudingeka uluthenge kanye nenombolo okufanele uyithenge.

4. Umbuzo: Iyiphi Indlela Engcono Kakhulu Yokuthuthukisa Amasignali Ami Omsakazo?

A: Ukufaka i-antenna yokusakaza ye-FM phezulu kuyindlela engcono kakhulu kuwe.

Kunezindlela ezintathu ongathuthukisa ngazo amasiginali we-FM: Ukufaka amasignali omsakazo we-FM phezulu, ukukhetha isidlulisi se-FM esinamandla amakhulu, nokukhetha izimpondo zokusakaza ze-FM ngenzuzo ephezulu. Ngokusobala, izindleko zendlela yokuqala zivaliwe kuze kufike kuziro. Futhi kuyindlela ephumelela kakhulu kuwe yokuthuthukisa amasiginali we-Fm.

Isiphetho

Sithemba ukuthi lokhu kwabelana ngebhulogi kungakusiza ukuthi uphathe kangcono isiteshi sakho somsakazo futhi unciphise izindleko ezingadingekile.
