Iyini i-Batwing Antenna futhi Isebenza Kanjani?

I-batwing antenna, noma i-super turnstile antenna, iyi-polarized (i-dipole ephambanayo, i-polarization evundlile) i-omnidirectional antenna ebukeka njenge-batwing noma i-bow tie, evame ukusetshenziswa ekusakazweni kwe-VHF ne-UHF.

I-Turnstile ne-Super Turnstile

I-antenna e-batwing empeleni isuselwa kuhlu lwe-dipole oluphambanayo olubizwa ngokuthi i-turnstile antenna.

Yize lokhu kwakamuva kusetshenziswa kumabhendi e-VHF kanye ne-UHF (cishe ama-30 MHz kuya ku-3 GHz) njengangaphambili, lena yakamuva inohlelo olubanzi lwezempi, futhi amandla emisebe angaphansi ngo-3dB kunemisebe ephezulu ye-dipole ye-wave eyisigamu enamandla afanayo. 

I-batwing antenna yakhelwe ukunqoba lokhu kubi.

Ukwakheka

I-antenna eshayayo yenziwe ngezinto ezimbili eziyisicaba eziyisicaba ezimise okwephiko. Amapheya amabili ezinto ze-bat wing ngayinye ngokuvamile afakwa ku-mast evamile esimweni esingu-90 ° perpendicular to another. 

Ngakho, ama-dipoles amabili we-bat wing antenna angathola imodi ye-omnidirectional (isigaba ngasinye sihlukile ngo-90 ° kwesinye, futhi kunezigaba ezine sezizonke, okungukuthi 360 ° omnidirectional). 

Ngakho-ke, lolu hlobo lwe-antenna lungaqhuba imisebe ye-polarization enezingqimba. Uma zakhiwe kahle (isb., isitaki esiqondile), izimpondo ezinjalo zingathola i-VSWR engu-1.1:1 noma ngaphansi kuka-30% womkhawulokudonsa futhi zithole inani elikhulu lenzuzo.

Yini Ehlanganisa Uhlelo Oluphelele Lwe-Batwing Antenna?

Okulandelayo yizingxenye eziyisisekelo zesistimu ye-antenna eshayayo:

• I-Batwing antenna cross element x2 (yondliwe ngokuzimela)
• Isihlukanisi samandla we-antenna
• I-Rigid Transmission Line (isb. 3-1/8'' rigid coax)
• I-Antenna mounting mast
• Ihhanisi lesigaba

Vele, ngaphezu kwale mishini, kusadingeka ukuthi unake:

1. Ubude bendawo emaphakathi (HAAT).
2. Ubude obuphansi
3. Ukuphakama kwe-antenna

Izicelo

Ungavamisile ukubona izithombe ku-Google zithi izimpondo eziningi ze-batwing zifakwe ziqondile ku-mast efanayo, futhi i-antenna ngayinye e-batwing ivamise ukuhlukaniswa ngokwehlukana (imvamisa cishe ubude begagasi obubodwa). Inhloso yalokhu ukukhulisa inzuzo enezingqimba. 

Phakathi kwazo, igama elithi "bay" lisetshenziselwa ukubhekisela ku-antenna eyodwa eshayayo. I-collinear array eyakhiwe ngokunqwabelanisa izimpondo eziningi zamaphiko elulwane zinganciphisa amandla emisebe engeziwe (imvamisa ibheke ku-axial direction) futhi inikeze inzuzo ephezulu kanye nokuphumayo okuphezulu, okwenza i-antenna eshayayo ifaneleke kakhulu ukusakaza phansi.

I-antenna eshayayo iphinde ibe wuthi olukhethwayo lomsakazo nethelevishini esezingeni eliphansi. Lokhu kungenxa yokuthi ingxenye ye-dipole ye-antenna eshayayo inganikeza umkhawulokudonsa obanzi we-antenna. 

Umkhawulokudonsa we-Broadband nokusebenza okuhle kakhulu kuyenza ikhange ukusetshenziswa ngabaphindayo be-ATV. Lesi sici sifaneleka ngokukhethekile ezinkampanini zokusakaza ezifuna ukusebenzisa uthi olulodwa ukuze zisize ama-transmitters amaningi adlulise amasignali e-TV.

Nakuba i-antenna ye-batwing iyi-antenna yokuqala yokusakaza ye-TV esetshenziswa kabanzi, ngaphezu kokuxhumana kwe-VHF (i-FM, i-TV), i-antenna ye-batwing nayo ivame ukusetshenziswa ekuxhumaneni kwezempi kanye nokuxhumana nge-satellite, ukubukeka kwabo kuyahlukahluka ngokuhlukile, ngeke ngikulethele imininingwane ngaphandle kokuthi ofuna ngikwenze, shiya umyalezo wakho futhi ungazise!

U-FMUSER: Umkhiqizi we-Antenna Wokuzuza Okuphezulu kwe-VHF

Njengomkhiqizi ochwepheshe kanye nomphakeli wama-antenna okusakaza aphiko lwelulwane, i-FMUSER kuze kube manje inikeze izixazululo eziphelele ze-turnkey kumakhulukhulu eziteshi zomsakazo nezethelevishini emhlabeni jikelele, okuhlanganisa:

• Ukuhlolwa kwekhwalithi yomkhiqizo ngaphambi kokuthunyelwa
• Ukuhlinzekwa kwamatheku amaningi asebenza kahle kakhulu we-batwing antenna namakhithi
• Ukusekelwa kwe-inthanethi kokufakwa kwe-antenna nokuqaqa
• Isevisi ethembekile yangemva kokuthengisa, njll. 

I-antenna yakho eshayayo ingamelana namashumi eminyaka omoya, imvula, iqhwa, nemibani eqondile, futhi izosebenzela iziteshi zakho zokusakaza ngokuphepha nangempumelelo isikhathi eside.
