Antenna ea Batwing ke eng, 'me e sebetsa joang?

The batwing antenna, kapa super turnstile antenna, ke polarized (cross dipole, horizontal polarization) omnidirectional antenna e nang le ponahalo e ts'oanang le batwing kapa bow tie, e sebelisoang hangata ho phatlalatso ea khoebo ea VHF le UHF.

Turnstile le Super Turnstile

The batwing antenna e hlile e nkiloe ho cross dipole array e bitsoang turnstile antenna.

Leha ea morao-rao e sebelisoa ho lihlopha tsa VHF le UHF (hoo e ka bang 30 MHz ho 3 GHz) joalo ka ea pele, ea morao-rao e na le ts'ebeliso e pharalletseng ea sesole, 'me matla a mahlaseli a tlase ho 3dB ho feta mahlaseli a mangata a halofo ea wave dipole ka matla a tšoanang. 

The batwing antenna e etselitsoe ho hlola bothata bona.

sebopeho

Lenakana la batwing le entsoe ka likarolo tse peli tse ikhethang tse nang le sebopeho sa mapheo se bataletseng. Lipara tse peli tsa antenna e 'ngoe le e' ngoe ea lepheo la bat hangata li kengoa holim'a mast e tloaelehileng sebakeng sa 90 ° perpendicular ho e 'ngoe. 

Ka hona, li-dipole tse peli tsa antenna ea lepheo la bat li ka fumana mokhoa oa omnidirectional (mohato o mong le o mong ke 90 ° o fapaneng le o mong, 'me ho na le mekhahlelo e mene ka kakaretso, ke hore 360 ​​° omnidirectional). 

Ka hona, mofuta ona oa antenna o ka tsamaisa mahlaseli a polarization a otlolohileng. Ha e hahiloe hantle (mohlala, stack e otlolohileng), li-antenna tse joalo li ka fumana VSWR ea 1.1: 1 kapa ka tlase ho 30% ea bandwidth le ho fumana phaello e ngata.

Ke Eng e Akaretsang Sisteme e Felletseng ea Batwing Antenna?

Lintlha tse latelang ke likarolo tsa mantlha tsa sistimi ea batwing antenna:

• Batwing antenna cross element x2 (fepa ka bohona)
• Se arola matla a antenna
• Rigid Transmission Line (mohlala, 3-1/8'' rigid coax)
• Sefate sa antenna
• Mokhahlelo oa marapo

Ha e le hantle, ho phaella ho lisebelisoa tsena, u ntse u lokela ho ela hloko:

1. Karolelano ea sebaka (HAAT) bophahamo
2. Bophahamo ba fatshe
3. Bophahamo ba antenna

dikopo

Hangata u ka bona linepe ho Google li re li-antenna tse ngata tsa batwing li kentsoe ka ho otloloha setulong se le seng, 'me lenakana le leng le le leng la batwing le lula le arohane (hangata hoo e ka bang bolelele bo le bong). Morero oa sena ke ho eketsa phaello e otlolohileng. 

Har'a tsona, lentsoe "bay" le sebelisoa ho bolela antenna e le 'ngoe ea batwing. Collinear array e entsoeng ka ho bokella manakana a mangata a mapheo a cradle a ka fokotsa matla a mangata a mahlaseli (hangata a le lehlakoreng la axial) 'me a fana ka phaello e phahameng le phaello e phahameng, e leng se etsang hore lenakana la batwing le tšoanelehe haholoanyane bakeng sa khaso ea fatše.

The batwing antenna hape ke lenakana le ratoang bakeng sa seea-le-moea le thelevishene tsa pele tsa maqhubu a tlase. Lebaka ke hobane karolo ea dipole ea antenna ea batwing e ka fana ka bandwidth e pharalletseng bakeng sa antenna. 

Broadband bandwidth le ts'ebetso e ntle haholo li etsa hore e khahle bakeng sa ts'ebeliso ea batho ba pheta-phetoang ba ATV. Tšobotsi ena e loketse haholo-holo lik'hamphani tsa khaso tse batlang ho sebelisa antenna e le 'ngoe ho thusa li-transmitters tse ngata ho fetisa melaetsa ea TV.

Le hoja antenna ea batwing e le ea pele e sebelisoang haholo ho phatlalatsoa ha antenna ea thelevishene, ho phaella ho puisano ea VHF (FM, TV), lenaka la batwing le boetse le sebelisoa ka mokhoa o tloaelehileng oa puisano ea sesole le puisano ea sathelaete, ponahalo ea bona e fapana ka tsela e fapaneng, nke ke ka u tlisetsa lintlha ntle le haeba u le sieo. o batla hore ke tlohele molaetsa wa hao mme o ntsebise!

FMUSER: Phaello e Phahameng ea VHF Batwing Antenna Manufacturer

Joaloka moetsi ea hloahloa le morekisi oa li-antenna tsa mapheo a bo-'mankhane, FMUSER ho fihlela joale e fane ka tharollo e felletseng ea liteishene tsa seea-le-moea le seea-le-moea-moea lefatšeng ka bophara, ho kenyelletsa:

• Tlhahlobo ea boleng ba sehlahisoa pele se romelloa
• Phepelo ea lisebelisoa tse ngata tse sebetsang hantle haholo tsa li-antenna le lisebelisoa
• Ts'ehetso ea marang-rang bakeng sa ho kenya antenna le ho qhaqha
• Ts'ebeletso e tšepahalang ka mor'a thekiso, joalo-joalo. 

The batwing antenna e ka mamella lilemo tse mashome tsa moea, pula, leqhoa le lehalima le tobileng, 'me e tla sebeletsa liteishene tsa hau tsa khaso ka mokhoa o sireletsehileng le ka katleho nako e telele.

Likarolo tse ka Sehloohong tsa Lihlahisoa tsa Rōna

• Sehlopha sa I (48.5-84 MHz)
• Sehlopha II (87-108 MHz)
• Sehlopha III (167-223 MHz)
• VSWR e tlase
