Sida Loo Doorto Dipole FM Anteenada 5 Tallaabo?

dipole FM anteeno wax iibsiga tallaabooyinka

  

Anteenada baahinta FM-ku waa mid ka mid ah qaybaha ugu muhiimsan nidaamka anteenada FM-ta, waxa ay ka caawisaa idaacadaha in ay baahiyaan intii suurtogal ah. 

 

Waxyaabaha xiisaha leh ayaa ah, anteenada FM-ka dipole gaar ahaan waxay helaysaa doorbidid sababtoo ah adeegsigeeda fudud. Laakiin weli, dad badan ayaa u muuqda inaysan wax fikrad ah ka haysan sida loo doorto anteenada dipole FM ee ugu wanaagsan ee baahinta.

 

Nasiib wanaag, waxaanu kuu diyaarinaa qaar ka mid ah talooyinka wax iibsiga ee waxtarka leh si ay kaaga caawiyaan. Inta aad raacdo 5tan qodob, xitaa haddii aad tahay qof ku cusub baahinta FM-ta, waxaad si fudud u dooran kartaa anteenada ugu wanaagsan ee dipole FM.

 

Sii wad sahaminta!

Tallaabada #1 Xaqiijinta Noocyada Anteenada

  

Anteenooyinka FM dipole waxay leeyihiin noocyo kala duwan waxayna leeyihiin astaamo kala duwan, xaqiijinta nooca aad u baahan tahay waxay kaa caawin kartaa inaad si buuxda u isticmaasho anteenada. 

  

Guud ahaan, anteenada dipole FM waxay u qaybsantaa 4 nooc oo waaweyn, anteeno gaaban oo gaaban, anteeno FM ah oo badhkeed ah, anteeno ballaadhan oo FM ah, anteeno FM duuban oo dipole ah. 

  

Waxaad u baahan tahay inaad qaadato go'aanka kama dambaysta ah ka hor intaadan dooran anteenada dipole FM, miyay tahay anteenada dipole gaaban ama anteenada laalaabtay ee dipole?

  

Talaabada # 2 Isbarbardhiga Awooda Soo saarista Gudbinta

  

Anteenada gudbiyaha dipole FM waa in lagu wanaajiyaa awoodda gudbinta ugu badan ee gudbiyaha FM-ka, haddii kale dhammaan nidaamka baahinta FM waa la jebin doonaa. 

  

Anteenada FM dipole ee kala duwan waxay leedahay awood gudbin oo kala duwan. Tusaale ahaan, awooda la qiimeeyay ee FMUSER FM-DV1 dipole FM anteeno waxa lagu beddeli karaa 10KW baahiyo kala duwan oo baahin ah. Markaa waxa lagu xidhi karaa gudbiye kasta oo FM ah oo leh awood gudbin oo ka hoosaysa 10KW.

  

Tallaabada #3 Doorashada Polarization Habboon

  

Anteenada FM dipole ee leh polarization ku habboon ayaa ka caawin karta idaacada FM-ka in ay ku xidhmaan dhegaystayaal badan. 

  

Asal ahaan, anteenada gudbiyaha dipole FM waxay leedahay 3 nooc oo polarization ah: polarized horizontal, vertical polarized, iyo polarized wareeg ah. Polarzation-ka anteenooyinka helaya iyo anteenooyinka gudbinaya waa in la is waafajiyaa. 

  

Tallaabada #4 Bixinta Feejignaanta Antenna VSWR

  

VSWR waxay u taagan tahay hufnaanta shaqada ee nidaamka RF, hoos u dhaca, hufnaanta shaqo ee sare ee nidaamka RF leeyahay. Guud ahaan, VSWR ka hooseeya 2.0 waa la aqbali karaa. 

  

Sidaa darteed, waxaad u baahan tahay inaad ogaato inay muhiim tahay in fiiro gaar ah loo yeesho tayada fiilooyinka iyo anteenooyinka FM-ka dipole, iyo in la ilaaliyo qalabka waqtiga loogu talagalay.

  

Tallaabada #5 Helitaanka Alaab-qeybiyeyaal La isku halleyn karo

  

Ku rakibida anteenooyinka dipole FM waxaa laga yaabaa inay weli ku adag tahay qof, gaar ahaan kuwa ku cusub FM-yada baahinta, maxaad u heli weyday alaab-qeybiye anteeno dipole fm ah oo la isku halayn karo sida FMUSER? 

  

Waxaan ku siin karnaa kaliya ma aha anteenooyinka FM-ka ugu wanaagsan, laakiin sidoo kale nidaamka anteenooyinka FM-ka ugu fiican si loo daboolo baahiyahaaga baahinta.

  

Su'aalaha Badiya La Weydiiyo

1. S: Waa maxay anteenada FM dipole?

J: Waa nooc ka mid ah anteenada FM-ta ah ee laga sii daayo oo ka kooban laba tiir.

  

Anteenada dipole FM waxay ka kooban tahay laba tiir ama qaybo dhererka tiirarka waxaa lagu go'aamiyaa inta jeer ee shaqada. Qeybta baahinta FM-ta waxay caadi ahaan ka fidsan tahay 87.5 MHz ilaa 108 MHz wadamada badankood.

2. S: Anteenada dipole FM ma jihad dhan baa mise mid jihaysan?

J: Waa dhinac walba.

  

Dhab ahaantii, dhammaan anteenooyinka FM-ka dipole waxay leeyihiin qaab shucaac guud ah. Maaddaama ay quwaddeedu 360 digrii agagaaraha anteenada, kulligood waa anteenooyin dhan walba ah.

3. S: Sidee loo Xisaabiyaa Dhererka Cunsurka Dipole FM Antenna?

J: Isticmaalka qaaciidada: L=468/F

  

Qaaciddadan, L waxay u taagan tahay dhererka anteenada, cagaha halka F ay u taagan tahay inta jeer ee loo baahan yahay, gudaha MHz. Sidaa darteed, dhererka curiye kasta wuxuu la mid yahay kala badh L..

4. S: Miyay FM-ka Dipole Anteennada Anteennada Wanaagsan yihiin?

J: Haa, oo waxay ku kasbadaan nicmo adeegsigeeda fudud.

  

Anteenooyinka baahinta FM-ka dipole waa mid ka mid ah anteenooyinka ugu fudud ee la dhiso, la dhiso ama la dhiso. Aad bay faa'iido u leeyihiin oo si fiican ayay u shaqayn karaan haddii meel sare laga dhiso.
