FMUSER 532-1602 kHz Medium Wave Biconical Antenna Kufikira 50kW Mphamvu Yolowetsa

Chani IH Medium Wave Bzojambula Antenna ndi How It Works

The medium wave biconical antenna ndi mtundu wa wideband antenna womwe umagwiritsidwa ntchito polandila mawayilesi mumayendedwe apakatikati. Zimapangidwa ndi zinthu ziwiri zofananira zooneka ngati koni zomwe zimayikidwa polunjika, zofanana ndi hourglass kapena ayisikilimu cones olumikizidwa pa maziko awo. Mapangidwe apaderawa amalola kulandila ma frequency angapo mkati mwa bandi yapakatikati, nthawi zambiri kuyambira 530 kHz mpaka 1710 kHz.

Onerani makanema athu opangira 10kW AM omwe ali pamalowo ku Cabanatuan, Philippines:

Mlongoti wapakatikati wothamanga wa biconical antenna umagwira ntchito motengera mfundo yama radiation yamagetsi ndi kulandila. Pamene mafunde a electromagnetic, onyamula chizindikiro cha wailesi, afika pa mlongoti, amachititsa kuti mphamvu yamagetsi ikhale yozungulira muzinthu za mlongotiyo. Izi zimayenda pakati pa ma cones awiri, ndikupanga gawo lamagetsi lamagetsi mozungulira mlongoti.

Maonekedwe a symmetrical antenna ya biconical amawonetsetsa kuti gawo lamagetsi lamagetsi limawala mozungulira mbali zonse, ndikupangitsa kuti likhale lonse. Zotsatira zake, mlongoti umatha kujambula ma wayilesi kuchokera kumakona onse, kulola kulandila kodalirika kuchokera mbali zosiyanasiyana.

Zinthu zooneka ngati cone za tinyanga tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono timapangidwa mwaluso kuti tikwaniritse kumveka kwa mafunde apakati. Resonance iyi imathandizira kusamutsa bwino mphamvu yamagetsi yolandirira ku cholandila cholumikizidwa kapena makina owulutsira.

Chifukwa cha kuthekera kwake kokulirapo komanso kulandila kwa omnidirectional, tinyanga tating'ono ting'onoting'ono timagwiritsidwa ntchito kwambiri pamawayilesi a wailesi. Kukhoza kwake kujambula zizindikiro kuchokera kumbali zonse kumapangitsa kuti zikhale zoyenera pazochitika zomwe kulandiridwa kosasinthasintha ndi kodalirika kumafunika. Mapangidwe ndi magwiridwe antchito a medium wave biconical antenna imathandizira kuti ikhale yogwira mtima pakuwonetsetsa kufalikira ndi kulandila kwa ma wayilesi apakatikati.

Main Features

1. No Ground Grid: Kapangidwe ka biconical kumachotsa kufunikira kwa gridi yapansi, kulola kuti pakhale chopondapo. Kusinthasintha kumeneku kumathandizira kuti mlongoti ukhazikike padenga kapena m'mapiri, ndikupatsa mwayi wosankha malo.
2. Kukhazikika Kwabwino Kwambiri: Ma cones apamwamba ndi apansi amathandizira mwachindunji kuyenda kwa mawayilesi, osakhudzidwa ndi zinthu zosakhazikika monga kusasunthika kwa nthaka, mikhalidwe ya nthaka, zomera, nyengo, ndi nyengo. Ma capacitor opangidwa mwapadera amphamvu kwambiri komanso otentha kwambiri amatsimikizira kugwira ntchito mokhazikika, ngakhale m'madera omwe kutentha kumapitilira madigiri 60 chaka chonse, osafunikira kusintha kwamanja.
3. Low Electromagnetic Pollution: The biconical antenna itengera njira yapadera yotumizira, kuwonetsetsa kumveka kwa radiator pama frequency onyamula. Zotsatira zake, gawo la radiation limangokhala pafupi ndi mlongoti, kuchepetsa kuipitsidwa ndi ma elekitiroma komanso kusokoneza nyumba zozungulira. Itha kuwonedwa ngati mlongoti wokonda zachilengedwe kapena "wobiriwira".
4. Kuchita Bwino Kwambiri kwa Radiation: Kupanda kutayika kwa nthaka, kuphatikizidwa ndi njira yapadera yofananira yomwe imagwiritsidwa ntchito pamaneti otumizira, kumawonjezera magwiridwe antchito a chiŵerengero cha mafunde oima ndi bandwidth. Potumiza mphamvu yolowera molunjika ku rediyeta kutengera chiwopsezo, mlongotiyo umakwaniritsa mphamvu zofananira ndi mlongoti wachikhalidwe λ/4 wavelength pomwe ukuchepetsa kukula kwake.
5. Chitetezo Chogwira Mphezi: Ma network inductance amafananizidwa kuti awonetsetse kuti kutulutsa kuchokera pa radiator kupita pansi sikudutsa 50 µH, yomwe ndi 1/40 yokha ya kutulutsa kwa nsanja yachikhalidwe. Kutetezedwa kwa katundu ku mphamvu ya mphezi ndi <0.3 Ω (chifupifupi inductance <1 µH), kumabweretsa chitetezo chabwino kwambiri cha mphezi.
6. Chitetezo, Kudalirika, ndi Kusamalira Zopanda: Chotsitsa chokhazikika komanso chodalirika chimakhala ndi maziko a machubu anayi, pomwe ndodo yakumtunda ya cone ndi zipsepse za ndodo zimapereka kukana kwa mphepo. Mphuno yapakatikati imakhala ndi njira yodzitchinjiriza yopangidwa mwapadera pamodzi ndi zida zingapo zophatikizika, kuwonetsetsa kuti mphepo ndi zivomezi zimalimbana kwambiri. Thupi la nsanjayo ndi lotentha kwambiri, limapereka ntchito yabwino kwambiri yolimbana ndi dzimbiri ndipo silifuna kukonzedwanso.
