I-FMUSER VHF Slot Antenna HD-RDT-014 ye-Band III (167 MHz ukuya ku-223 MHz) Ukusakaza

Cela Ukucaphuna

Iyini i-VHF Slot Antenna futhi Isebenza Kanjani?

I-VHF slot antenna ingenye evame kakhulu ukusakaza izimpondo yakhelwe ukudluliswa komsakazo ebhendini ye-VHF. Isetshenziswa kakhulu ezinhlelweni zokusakaza ze-TV ebangeni lefrikhwensi engu-167-223 MHz. 

Idatha ye-VHF slot antenna ine-polarization evundlile, iphethini yemisebe evundlile ye-omnidirectional, kanye nephethini yemisebe eqondile eqondile encane, efaneleka kakhulu ukusakazwa kwedijithali ne-analogi.

Design

I-antenna ye-VHF slot ikakhulukazi yakhiwe imbobo yemisebe efakwe esakhiweni sensimbi engagqwali. 

I-antenna cavity kanye nohlaka lwensimbi engagqwali bakha umzimba omkhulu we-VHF slot antenna. Umgodi wenziwe nge-aluminium alloy, futhi izakhi ezine ezikhazimulayo zakha i-resonator ye-aluminium engunxande.

 Cela Ukucaphuna

Lapho liklama i-cavity, ithimba lethu lonjiniyela lalicubungule ngokugcwele ukufakwa kwe-zero kanye nokutshekiswa kwe-beam: 

1. I-engeli yokutsheka: 0.5 degrees
2. Ukuzuza kwe-antenna: 11 dB
3. Imisebe (Evundlile): i-omnidirectional.

Uhlaka lwensimbi engagqwali lunemisebenzi yokufaka nokuqiniswa ukuze kuqinisekiswe ukuzinza komgodi wemisebe, futhi futhi lunemisebenzi yemisebe nokuvikela ukukhanya. 

Njengoba umgodi omkhulu kulula ukuwohloka, ifreyimu yensimbi engagqwali ingaqinisekisa ubulukhuni nokuzinza kwe-radiation cavity. 

Uhlaka lwensimbi engagqwali lungalungiswa ngokuqondile ohlangothini lombhoshongo ngaphandle kokushintsha ukuma komgodi.

Ukwakheka

Ngokuvamile, ukwakheka kwe-antenna ye-VHF ilula futhi ngokuvamile iqukethe izici ezilandelayo:

• Insimbi yokuqinisa
• Isembozo sokuvikela
• Okuphakelayo okuqinile
• I-Bracket
• Imbobo yokufaka
• Uhlaka lokusekela
• Umzimba oyinhloko we-antenna
• Ikhava ye-Fiberglass

Material

Mayelana nezinto zokwakha, ama-antenna ethu e-VHF akhiqizwa ngezinto ezilandelayo:

• Ithusi lasolwandle
• Copper
• Aluminum
• I-Virgin Teflon

Yini Equkethe Uhlelo Oluphelele lwe-VHF Slot Antenna?

Okulandelayo yi-slot eyisisekelo ye-VHF uhlelo lwe-antenna izakhi:

1. Ngokuzimele ondliwe VHF slot antenna
2. Indawo yokuvikela (ikhava yesikhala noma i-radome egcwele evaliwe)
3. Ikhebuli ye-antenna coaxial (imvamisa ikhebuli yokuphakelayo, isb.1-5/8'' coax)
4. Ikhebuli yokuphakelayo enengcindezi
5. I-Antenna Mounting Mast/Bracket

Vele, ngaphezu kwale mishini, ngesikhathi sokufakwa, kusadingeka ukuthi unake:

1. Indawo yokufaka i-antenna. Ungakwazi ukukhweza ama-antenna ethu e-VHF noma ngaphezulu kombhoshongo, ohlangothini lombhoshongo, noma ubheke phansi. Uma ifakwe eceleni, cabangela ububanzi bombhoshongo noma ububanzi bensika ukuze uthole imisebe evundlile enhle. Ngokuvamile, amaza amaza e-VHF made futhi ububanzi bensika bunomphumela omncane.
2. Ukuze uthole inzuzo enkulu. Beka izimpondo ezimbili noma ngaphezulu ziqonde. Ukukhetha okunengqondo kobude bomugqa wokudlulisa wesiguquli somugqa kanye nesiphakeli se-coaxial phakathi kwamanodi kungaxazulula kangcono izinkinga zokufakwa kwe-zero-fill nokutshekiswa kwe-beam.
3. Ubude obuphansi
4. Ukuphakama kokufakwa kwe-antenna

FMUSER: Inzuzo ephezulu VHF Slot Antenna Umkhiqizi

I-FMUSER inikeze amakhulukhulu abasakazi be-TV emhlabeni wonke izisombululo ze-turnkey ezihlanganisa ukusebenza nokuvumelana nezimo, okuhlanganisa izinsiza zekhwalithi ephezulu ze-antenna slot, imiyalelo yokufaka ku-inthanethi, isevisi ephelele yangemva kokuthengisa, njll. 

Siqinisekisa ukuthi i-slot yakho I-antenna izofaniswa ngokunembile nombhoshongo wakho wokusakaza futhi izoqhubeka ikusebenzela amashumi eminyaka ekusebenzeni okuphezulu kokusakaza.

Izici Eziyinhloko Zemikhiqizo Yethu

• I-Band III (167-223 MHz)
• Inqubo yokukhiqiza enokwethenjelwa (ekhiqizwe ngethusi, ithusi, i-aluminium, ne-PTFE emsulwa)
• Idizayini yomsebenzi osindayo (ukumelana nokugqwala, ukumelana nomoya, ukumelana nokudlidliza, njll.)
• Ezinye izengezo zamukelwe, sicela usithinte ukuze uthole okwengeziwe (ukuphatha amandla e-antenna ebonisa ukonga kuvumela ukwanda. Itholakala ezilinganisweni zamandla asuka ku-1kW ukuya ku-90kW, isekela i-horizontal, circular, ne-elliptical polarization, i-azimuth kanye nezindlela zokuphakama, ingcindezi noma i-non-pressurized , njll.)
• Isilinganiso segagasi sokuma esihle kakhulu.
• Ukugcwalisa okuyi-null Okujwayelekile Okusindayo
• Okukhethwa kukho okuvundlile, okuyi-elliptical, noma okuyindilinga kuyatholakala.
• Ama-azimuth ajwayelekile kanye nezindlela zokumbondelana ngokwezifiso ziyatholakala.
• Amaradomu ayingxenye nagcwele yokulayisha umoya ophansi (kuyakhetheka)
• Igayidi yokufaka ku-inthanethi (sicela usithinte uma udinga isiqondiso esisendaweni)
• I-soldering yengxenye eqinisekisiwe ngokobuchwepheshe
• Ukuhlola ukuphepha nokusebenza ngaphambi kokushiya imboni
• Izintambo eziphakelayo nezinye izesekeli ze-antenna (kuyakhetheka)
