Ungakhetha kanjani i-Dipole FM Antenna ngezinyathelo ezi-5?

dipole FM antenna ukuthenga izinyathelo

  

I-antenna yokusakaza ye-FM ingenye yezingxenye ezibaluleke kakhulu zohlelo lwe-antenna ye-FM, isiza iziteshi zomsakazo ukusakaza ngangokunokwenzeka. 

 

Okuthakazelisayo ukuthi, i-antenna ye-FM dipole ithandwa kakhulu ngenxa yokusetshenziswa kwayo okulula. Kodwa noma kunjalo, abantu abaningi babonakala bengazi ukuthi bangakhetha kanjani i-antenna ye-dipole ye-FM engcono kakhulu yokusakaza.

 

Ngenhlanhla, silungiselela amathiphu okuthenga awusizo ukuze akusize. Uma nje ulandela lezi zeluleko ezi-5, noma ungumfundi oqalayo kwezokusakaza kwe-FM, ungakhetha kalula i-antenna ye-FM engcono kakhulu.

 

Qhubeka uhlole!

Isinyathelo#1 Ukuqinisekisa Izinhlobo Ze-Antenna

  

Ama-antenna e-FM anezinhlobo ezahlukene futhi anezici ezihlukile, ukuqinisekisa uhlobo oludingayo kungakusiza ukuba ulusebenzise ngokugcwele uthi. 

  

Sekukonke, i-antenna ye-dipole FM ihlukaniswe yaba izinhlobo ezi-4 eziyinhloko, i-dipole antenna emfushane, i-antenna ye-dipole fm eyingxenye, i-FM broadband dipole antenna, i-FM egoqiwe i-dipole antenna. 

  

Udinga ukwenza isinqumo sokugcina ngaphambi kokukhetha i-antenna ye-dipole FM, ingabe i-dipole antenna emfushane noma i-dipole antenna egoqiwe?

  

Isinyathelo#2 Ukufanisa Amandla Wokuphuma Kwe-Transmitter

  

I-antenna ye-dipole transmitter ye-FM kufanele ifaniswe namandla amakhulu okudlulisela omsakazo we-FM, noma lonke uhlelo lokusakaza lwe-FM luzophulwa. 

  

I-antenna ye-dipole ye-FM inamandla ahlukene okudlulisa. Isibonelo, amandla alinganiselwe we-FMUSER FM-DV1 dipole FM antenna angenziwa ngendlela oyifisayo abe ngu-10KW ngezidingo ezahlukene zokusakaza. Ngemuva kwalokho ingaxhunywa nanoma yimaphi ama-transmitters omsakazo we-FM anamandla okudlulisa angaphansi kuka-10KW.

  

Isinyathelo#3 Ukukhetha I-Polarization Efanelekayo

  

I-antenna ye-FM ene-polarization efanelekile ingasiza isiteshi sakho somsakazo we-FM sixhunywe ngabalaleli abaningi. 

  

Ngokuyisisekelo, i-antenna ye-dipole transmitter ye-FM inezinhlobo ezi-3 ze-polarization: i-horizontal polarized, vertical polarized, kanye ne-circular polarized. I-polarzation yama-antenna amukelayo kanye nezimpondo ezidlulisayo kufanele kuhambisane. 

  

Isinyathelo#4 Ukunaka i-Antenna VSWR

  

I-VSWR imele ukusebenza kahle kohlelo lwe-RF, uma luphansi, ukusebenza kahle okuphezulu kohlelo lwe-RF olunakho. Ngokuvamile, i-VSWR engaphansi kuka-2.0 iyamukeleka. 

  

Ngakho-ke, udinga ukuqaphela ukuthi kubalulekile ukunaka izinga lezintambo kanye nezimpondo ze-dipole FM, nokugcina okokusebenza ngesikhathi.

  

Isinyathelo#5 Ukuthola Abahlinzeki Abathembekile

  

Ukufaka ama-antenna e-FM mhlawumbe kusenzima kumuntu, ikakhulukazi kulabo abasakazi be-FM, kungani ungatholi umphakeli onokwethenjelwa we-dipole fm onjenge-FMUSER? 

  

Asikwazi ukukunikeza kuphela izimpondo ezingcono kakhulu ze-FM ze-dipole, kodwa futhi nohlelo oluhle kakhulu lwezinhlelo ze-FM zokuhlangabezana nezidingo zakho zokusakaza.

  

imibuzo ejwayelekile ukubuzwa

1. Umbuzo: Iyini i-dipole FM antenna?

A: Iwuhlobo lwe-antenna yokusakaza ye-FM equkethe izigxobo ezimbili.

  

I-antenna ye-dipole FM iqukethe izigxobo noma izingxenye ezimbili kanti ubude bezigxobo bunqunywa imvamisa yokusebenza. Ibhendi yokusakaza ye-FM imvamisa ukusuka ku-87.5 MHz iye ku-108 MHz emazweni amaningi.

2. Q: Ingabe i-antenna ye-FM i-omnidirectional noma iqondise?

A: Iwukuqondisa konke.

  

Empeleni, wonke ama-antenna e-dipole FM anephethini yemisebe ejwayelekile. Njengoba amandla ayo asakazwa ngamadigri angu-360 eduze kwe-antenna, wonke angama-omnidirectional antenna.

3. Q: Ungabala Kanjani Ubude Bezinto Ze-Dipole FM Antenna?

A: Ukusebenzisa ifomula: L=468/F

  

Kule fomula, u-L umele ubude bothi, ezinyaweni kuyilapho u-F emelela imvamisa edingekayo, ngo-MHz. Ngakho-ke, ubude be-elementi ngayinye bulingana nohhafu we-L.

4. Umbuzo: Ingabe I-FM Dipole Antennas Ilungile?

IMP: Yebo, futhi bathola umusa ngokuyisebenzisa kalula.

  

Ama-antenna e-FM asakazwayo angenye yezimpondo ezilula ukwakha, ukwakha noma ukumisa. Ziwusizo kakhulu futhi zingenza kahle kakhulu uma zakhiwe endaweni ephakeme. 

  

Isiphetho

  

Kuleli khasi, sithola indlela yokukhetha i-antenna ye-dipole ye-FM ehamba phambili, kusukela ekuqinisekiseni izinhlobo zezimpondo ze-dipole, i-VSWR ye-antenna, futhi ekugcineni kuye ekukhetheni umphakeli ongcono kakhulu.

  

Okuqukethwe okukhulunywe ngenhla kusiza ukwehlisa izindleko zakho zokuthenga futhi kungakusiza ukwakha ukuqonda okungcono kwe-RF uma ungumuntu osanda kuhlanganyela kwezokusakaza.

  

U-FMUSER ungomunye wabahlinzeki be-antenna be-FM abahamba phambili e-China, xhumana nochwepheshe bethu be-RF, futhi uthole ikhotheshini yakamuva yemishini yethu yokusakaza, imikhiqizo engcono kakhulu, amanani angcono kakhulu!
