Konke mayelana ne-Yagi Antenna

I-antenna ye-Yagi isetshenziswa kabanzi emkhakheni wokusakazwa komsakazo. Yini okufanele siyazi nge-Yagi Antenna? Ake sibe nokuqonda okufushane kwe-Yagi Antenna kuqala.

Incazelo

I-antenna ye-Yagi iwuhlobo lwe-antenna, ehlanganisa izici ezimbili noma ngaphezulu ezihambisanayo ze-antenna. Ukwenza i-antenna ye-Yagi, ngokuvamile idinga into eyodwa eshayelwayo exhunywe nesidlulisi njengesidlulisi somsakazo we-FM ngekhebula yokudlulisela kanye "nezakhi ze-parasitic" ezengeziwe ngaphandle kokuxhumeka kukagesi. Futhi ngokuvamile ihlanganisa isibonisi nanoma iyiphi inombolo yabaqondisi.

Izicelo

Njengoba iboniswa amandla okuzuza okuphezulu nokuqondisa, ifaneleka ngokukhethekile ukudluliswa kwephoyinti kuya kwephuzu, ukudluliswa kwe-TV, nokudluliswa kwamasignali omsakazo anamandla aphansi. Isibonelo, kubasakazi be-FM, ingasetshenziswa ekusakazweni kwamasiginali ye-FM isuka estudiyo ye-FM iye esiteshini somsakazo we-FM. Ingathuthukisa kakhulu amasiginali we-FM. Nansi enye ye-antenna yethu ye-UHF Yagi TV ethengiswa kakhulu yesonto lokushayela:

I-Antenna eyi-12 ehamba phambili ye-UHF Yagi TV - Okuningi

Isisindo

Njengokwakhiwa kwayo okulula, ayidingi izinto eziningi zokwakha, eza nomthwalo womoya ongasindi nophansi. Kusho ukuthi inekhono elihle kakhulu lokumelana nomoya.

Inani

I-antenna ye-Yagi cishe ingenye yezimpondo ezisebenza kakhulu. Ngaphandle kwezindleko eziningi, ungathenga i-antenna ye-Yagi ngokusebenza okuhle. Ngisho noma udinga ukwakha uhlu lwe-antenna yokuqondisa, udinga nje ukuhlanganisa izimpondo ezine ze-Yagi ndawonye.

Thola

Ku-antenna ye-Yagi, amandla okuthuthukisa amasignali omsakazo ancike enanini lezinto. Uma inama-elementi amaningi, ingathuthukisa amasignali kangcono. Inzuzo ye-antenna ye-Yagi ingafinyelela ku-20dBi, ikakhulukazi ekudluliselweni komsakazo onamandla aphansi kanye nokudluliswa kwephoyinti ukuya ephuzwini.

Ukufakwa

Ngenxa yesakhiwo sayo esilula, wonke umuntu angafaka i-antenna ye-Yagi kalula futhi ayihambise kalula. Ngasikhathi sinye, ingabuye ihlanganiswe ibe yi-omnidirectional antenna nganoma yisiphi isikhathi ngokwezidingo, efaneleka kakhulu abasakazi be-FM abangochwepheshe abanezidingo eziyinkimbinkimbi nezihlukahlukene.

imibuzo ejwayelekile ukubuzwa

1. Q: Inde Kangakanani Ingxenye Eqhutshwayo Ye-Yagi Antenna?

A: I-elementi eshayelwayo ilingana no-1/2 we-wavelength.

Ubude obulinganiselwe be-elementi eshayelwayo yothi lwe-Yagi buyi-1/2 ubude begagasi. Ngakho-ke uma usebenzisa i-Yagi Antenna ebangeni eliphakeme lemvamisa, izakhi zifushane.

2. Q: Isebenza kanjani i-Yagi Antenna?

A: I-antenna ye-Yagi isebenza ngokusebenzisana kwezingcezu ezine ezibalulekile.

• Isici Esiqhutshwayo - Iphuzu lokuthi i-antenna ye-Yagi ixhunywe nomugqa wokuphakelayo.
• Um(aba)qondisi - Isetshenziselwa ukunikeza i-antenna amandla okuqondisa kanye nenzuzo.
• Line - Iwumgogodla we-antenna futhi isetshenziselwa ukubamba abaqondisi nezibonisi futhi ixhume kusici esishayelwayo.
• Umbukiso - Isetshenziselwa ukwenqaba amasiginali ngaphandle kobubanzi bayo futhi ikhulise okungaphakathi.

3. Q: Luyini Ububanzi be-antenna ye-Yagi?

A: Isebenza kububanzi bemvamisa ye-3 - 3000 MHz.

Ama-antenna e-Yagi angasetshenziswa ebangeni lemvamisa ukusuka ku-3 - 3000 MHz, nebanga lokusebenza elingcono kakhulu elingaphansi kuka-1500 MHz.

4. Q: Ingabe inzuzo ende ye-Yagi antenna ifanele i-TV yedijithali?

A: Impendulo ithi YEBO.

Kodwa kufanele uqaphele ukuthi i-antenna ye-Yagi inzima ukuthola inzuzo ephezulu ngenkathi inomkhawulokudonsa owanele wokumboza iziteshi ezanele ze-UHF. Ibanga lokuvama kwe-antenna ye-Yagi lincane kakhulu. 

Isiphetho

Nge-antenna ye-Yagi, kungakhathaliseki ukuthi uhlela ukuyisebenzisa ohlelweni lokuxhumanisa i-studio transmitter noma unikeze izinsizakalo zokusakaza ze-FM/TV emphakathini ngayo, akudingeki ukhathazeke ngekhwalithi yamasignali. Uma udinga ukuthenga i-antenna ye-Yagi, xhumana ne-FMUSER khona manje!
