DIY an FM Radio Dipole Eriya | FMUSER BROADCAST

 Eriyar dipole FM ita ce mafi sauƙi kuma mafi girman nau'in eriya, don haka yana da sauƙi ga kowa ya yi nasa, wanda kawai ke buƙatar wasu abubuwa masu sauƙi. da DIY FM dipole eriya zaɓi ne mai amfani kuma mai rahusa idan rediyonka yana buƙatar eriya ta wucin gadi. Don haka ta yaya ake DIY eriyar dipole FM? Labarin zai gaya muku.

Menene Antenna Dipole FM?

Yana da mahimmanci a sami ɗan taƙaitaccen fahimtar eriyar dipole FM kafin saita game da yin naku. A fagen rediyo da sadarwa, eriyar dipole FM ita ce irin eriyar da aka fi amfani da ita kuma mafi sauƙi. Yana da siffofi na fili: yana kama da kalmar "T", wanda ya ƙunshi masu gudanarwa guda biyu masu tsayi daidai kuma daga ƙarshe zuwa ƙarshe. An haɗa ƙafafun su tare da kebul. Kebul ɗin na iya zama buɗaɗɗen kebul, kebul biyu, ko kebul na coaxial. danna nan

Ya kamata a lura cewa ya kamata a yi amfani da balun lokacin amfani da kebul na coaxial saboda kebul na coaxial wani nau'in kebul ne mara daidaituwa amma eriyar dipole FM nau'in eriya ce mai daidaitacce. Kuma balun na iya sanya su a daidaita su da juna.

Kuna buƙatar shirya wasu kayan don yin eriyar dipole FM kuma. Gabaɗaya su ne:

• Twin flex - Twin mains flex yana da kyau, amma zaka iya maye gurbinsa da wasu wayoyi, kamar tsoffin wayoyi masu magana, muddin juriyarsu ta kusa 75 ohms.
• Tie wrap - Ana amfani da shi don tabbatar da tsakiyar eriyar dipole FM da kuma hana sassauƙan buɗewa sama da abin da ake buƙata.
• Iri ko igiya - Ana amfani da shi don kiyaye ƙarshen eriyar dipole FM zuwa wani wuri (idan an buƙata).
• Masu haɗawa - Ana amfani dashi don haɗa eriyar FM zuwa kebul na coaxial.

Ana iya samun waɗannan kayan a cikin rayuwar yau da kullun. Kuna iya amfani da waɗanda aka samo a cikin tari don yin VHF eriyar dipole FM.

Sannan ana buƙatar ƙididdige tsawon eriyar dipole na VHF FM ku. Kuna iya lissafta bisa ga wannan tsari:

L=468/F : L yana nufin tsayin eriya, don haka tsayin mai gudanarwa yana buƙatar raba ta 2. F shine mitar aiki a MHz. Lokacin da waɗannan na sama suka shirya, zaku iya fara yin eriya.

Yana da sauƙi don yin eriyar dipole VHF FM ta talakawa, wacce kawai ke buƙatar matakai 4 masu sauƙi. Bi jagorar da ke ƙasa!

• Rarrabe kebul - Rarraba wayoyi biyu masu ɓoye na kebul.
• Gyara wurin tsakiya - Tuna tsawon jagoran ku? Bari mu ɗauka cewa yana da 75 centimeters. Lokacin da jagoran ya isa tsayin 75 cm, yana dakatar da raba wayoyi. Sa'an nan kuma ku ɗaure tsakiya tare da abin da aka rufe a wannan lokacin. Kuma wannan ita ce cibiyar eriyar dipole FM.
• Daidaita tsawon mai gudanarwa - Sa'an nan kuma za ku iya daidaita tsawon lokacin dan kadan. Saboda akwai abubuwa da yawa da ke shafar madaidaicin a cikin tsarin tsawon jagora, ba shi yiwuwa a zama daidai a kowane lokaci. Idan kana buƙatar mafi girma mitar aiki, za ka iya rage tsawon shugaba dan kadan.
• Gyara eriya - A ƙarshe, ɗaure ƙuri'a a ƙarshen waya don ku iya gyara eriya tare da wasu murƙushe wayoyi. Lokacin shigar da eriyar dipole FM, kula da nisantar abubuwa na ƙarfe, ko ingancin liyafar siginar za ta ragu. 

Za a iya amfani da mai karɓar VHF FM don ƙirar 75-ohm da 300-ohm. Eriyar dipole FM da ke sama ta dace da ƙirar 75-ohm. Idan kuna son amfani da ƙirar 300-ohm, zaku iya gwada hanyoyi biyu:

1. Haɗa eriyar ku ta DIY 75-ohm dipole tare da kebul na coaxial tare da balun
2. Sayi kebul na FM 300 ohm akan layi kuma yi eriyar dipole 300-ohm daidai da yin eriyar dipole 75-ohm.

An lura cewa ana ba da shawarar kawai don amfani da eriyar dipole na DIY FM don rediyo ko mai karɓar sauti. Idan kana buƙatar eriya don watsa rediyon FM, da fatan za a saya ƙwararrun eriyar dipole FM daga ƙwararrun masu ba da kayan aikin rediyo, kamar FMUSER.

Menene Balun Ga Dipole?

Ka'idar Baron yayi kama da na taransifoma. Balun na'urar lantarki ce da ke juyawa tsakanin sigina mai daidaitacce da sigina mara daidaituwa, ko layin ciyarwa. 

Yaushe Zan Yi Amfani da Antenna Balun?

Ana amfani da ma'auni a wurare da yawa don canzawa tsakanin ma'auni & yanayi mara daidaituwa: yanki ɗaya maɓalli shine don mitar rediyo, aikace-aikacen RF don eriya. Ana amfani da ma'aunin RF tare da eriya da yawa da masu ciyar da su don canza madaidaicin abinci ko layi zuwa mara daidaituwa, Tun da eriyar dipole eriya ce mai daidaitacce kuma kebul na coaxial kebul ne mara daidaituwa, kebul na coaxial yana buƙatar amfani da balun don canza coaxial. kebul a cikin madaidaicin kebul.

Menene Daban-daban Nau'ikan FM Dipole Eriya?

Akwai manyan nau'ikan eriyar dipole FM guda huɗu:

• eriya dipole rabin igiyar ruwa
• Multi rabin-kalaman dipole eriya
• Eriya mai ninkewa
• gajeren dipole 

Wane Irin Feeder Ne Mafi kyawun FM Dipole Eriya ? Wanne Hanyar Ciyarwa Yafi Kyau?

Eriyar dipole eriya ce mai daidaitacce, don haka yakamata kuyi amfani da madaidaicin ciyarwa, wanda yake gaskiya ne a ka'idar. Koyaya, ba a cika amfani da madaidaicin ciyarwa ba saboda yana da wahalar aiki a cikin gine-gine kuma yana aiki ne kawai ga ƙungiyar HF. Ana amfani da ƙarin igiyoyi na coaxial tare da balun.

Ana amfani da eriyar dipole FM a cikin yanayin watsa shirye-shiryen rediyo daban-daban, kamar rediyon FM na sirri saboda sauƙi, inganci, da ƙarancin farashi. Amma idan kuna buƙatar gina tashar rediyo, samun ingantaccen mai samar da kayan aikin rediyo shine mafi kyawun zaɓinku. FMSUER irin wannan ƙwararren ƙwararren ne kuma abin dogaro na kayan aikin watsa shirye-shiryen rediyo da mafita, gami da masu watsa shirye-shiryen rediyo na FM masu amfani da rahusa don siyarwa, madaidaitan eriyar dipole FM don siyarwa, da sauransu. Idan kuna neman waɗannan, da fatan za ku iya tuntuɓar mu!
