Kodi Batwing Antenna ndi Chiyani Ndipo Imagwira Ntchito Motani?

The batwing antenna, kapena super turnstile antenna, ndi polarized (mtanda dipole, yopingasa polarization) omnidirectional mlongoti ndi maonekedwe ofanana ndi batwing kapena uta tie, umene umagwiritsidwa ntchito kwambiri VHF ndi UHF kuwulutsa malonda.

Turnstile ndi Super Turnstile

Mlongoti wa batwing umachokera ku gulu la dipole lotchedwa turnstile antenna.

Ngakhale zotsirizirazi zimagwiritsidwa ntchito m'magulu a VHF ndi UHF (pafupifupi 30 MHz mpaka 3 GHz) monga akale, omalizawa ali ndi ntchito zambiri zankhondo, ndipo mphamvu ya radiation ndi 3dB yotsika kuposa ma radiation a theka la dipole ndi mphamvu yomweyo. 

Mlongoti wa batwing adapangidwa kuti athetse vutoli.

kapangidwe

Mlongoti wa batwing umapangidwa ndi zinthu ziwiri zapadera zooneka ngati mapiko. Mawiri awiri azinthu za mlongoti aliyense wa mapiko a mleme nthawi zambiri amayikidwa pamtengo wamba pamtunda wa 90 ° perpendicular kwa wina ndi mnzake. 

Chifukwa chake, ma dipoles awiri a mapiko a mleme amatha kupeza njira ya omnidirectional (gawo lililonse ndi 90 ° losiyana ndi linalo, ndipo pali magawo anayi onse, mwachitsanzo 360 ° omnidirectional). 

Chifukwa chake, mtundu uwu wa mlongoti ukhoza kuyendetsa cheza chopingasa polarization. Zikamangidwa bwino (mwachitsanzo, zopingasa zowongoka), tinyanga totere zimatha kupeza VSWR ya 1.1: 1 kapena kuchepera 30% ya bandwidth ndikupeza phindu lalikulu.

Zomwe Zimakhala ndi Kachitidwe Kathunthu ka Batwing Antenna?

Zotsatirazi ndi zigawo zikuluzikulu za batwing antenna system:

• Batwing antenna cross element x2 (yodyetsedwa yokha)
• Chogawa mphamvu cha antenna
• Mzere Wosasunthika Wotumiza (monga 3-1/8'' olimba coax)
• Kuyika kwa antenna
• Phase harness

Zachidziwikire, kuwonjezera pazida izi, muyenerabe kulabadira:

1. Avereji ya mtunda (HAAT) kutalika
2. Kutalika kwapansi
3. Kutalika kwa antenna

Mapulogalamu

Nthawi zambiri mumatha kuwona zithunzi pa Google zonena kuti tinyanga zopindika zingapo zimayikidwa molunjika pamlongoti womwewo, ndipo mlongoti uliwonse womwe umamenyedwera umakhala motalikirana motalikirana (nthawi zambiri pafupifupi utali wamtundu umodzi). Cholinga cha izi ndikuwonjezera phindu lopingasa. 

Pakati pawo, mawu oti "bay" amagwiritsidwa ntchito kutanthauza mlongoti umodzi womwe umagunda. Gulu la ma collinear lomwe limapangidwa poyika tinyanga ta mapiko a cradle bat amatha kuchepetsa mphamvu ya radiation (nthawi zambiri ku axial direction) ndikupereka phindu lalikulu komanso kupindula kwakukulu, zomwe zimapangitsa kuti mlongoti wa batwing ukhale woyenera kuwulutsa pansi.

Mlongoti wa batwing ndiyenso mlongoti wokondeka wamawayilesi ocheperako komanso wailesi yakanema. Izi ndichifukwa choti gawo la dipole la batwing antenna limatha kupereka bandwidth yokulirapo ya mlongoti. 

Kuthamanga kwa Broadband ndi magwiridwe antchito abwino kwambiri kumapangitsa kuti ikhale yosangalatsa kugwiritsa ntchito obwereza ATV. Khalidweli ndiloyenera makampani owulutsa mawu omwe akufuna kugwiritsa ntchito mlongoti umodzi kuthandiza ma transmitters angapo kufalitsa ma siginecha a TV.

Ngakhale mlongoti wa batwing ndi mlongoti woyamba womwe umagwiritsidwa ntchito kwambiri pa TV, kuwonjezera pa kulankhulana kwa VHF (FM, TV), mlongoti wa batwing umagwiritsidwanso ntchito polankhulana ndi asilikali ndi kuyankhulana kwa satana, maonekedwe awo amasiyana mosiyana, sindidzakubweretserani tsatanetsatane pokhapokha ngati mukufunikira. mukufuna ndisiye uthenga wanu ndidziwitse!

FMUSER: Wopanga Antenna Wopeza Bwino Kwambiri wa VHF

Monga akatswiri opanga komanso ogulitsa ma antennas owulutsa mapiko a bat, FMUSER yapereka mayankho athunthu pamawayilesi ndi wailesi yakanema padziko lonse lapansi, kuphatikiza:

• Kuyang'anira khalidwe la mankhwala musanatumize
• Kupereka kwapamwamba magwiridwe antchito angapo a batwing antenna ndi zida
• Thandizo pa intaneti pakuyika kwa antenna ndi kuphatikizika
• Utumiki wodalirika pambuyo pa malonda, ndi zina zotero. 

Antenna yanu yopumira imatha kupirira mphepo, mvula, madzi oundana, ndi kuwomba kwamphezi kwazaka zambiri, ndipo idzakutumizirani mawayilesi anu motetezeka komanso moyenera kwa nthawi yayitali.

Mbali Zazikulu Zazinthu Zathu

• Band I (48.5-84 MHz)
• Gulu II (87-108 MHz)
• Gulu III (167-223 MHz)
• Mtengo wapatali wa magawo VSWR 
• Wide frequency band 
• Kuika kwapafupi 
• ntchito khola 
• Moyo wautali, 0 kukonza
• Kupeza kwakukulu
• Bandwidth yayikulu
• Mapangidwe apamwamba (kukana dzimbiri, kukana mphepo, kukana kugwedezeka, etc.)
• Zowonjezera zina zalandiridwa, chonde titumizireni kuti mumve zambiri (mwachitsanzo NTSC & CCIR tchanelo, ziro IMD, malata, chitsulo chopendekera ndi null fill, mizere ya Interbay, etc.)
