Onse owulutsa mawayilesi a FM komanso eni mawayilesi amalabadira kwambiri momwe ma antenna amawulutsira a FM amachitira chifukwa zimatsimikizira kuchuluka kwa owonera angalandire mawayilesi awo.

Ngati mukukonzekera kupanga wayilesi ya FM, kapena mukufuna kukonza ma wayilesi a FM kuti mukulitse bizinesi yanu, kapena simukukhutira ndi momwe antenna wawayilesi ya FM ikugwirira ntchito, chingakhale chisankho chabwino kusintha Kuwulutsa kwa antenna ya FM ndikuchita bwino. Koma kodi mukudziwa zomwe muyenera kulabadira posankha mlongoti wa FM?

Pokhala ndi zaka zambiri pawailesi ya FM, tikudziwitsani mwachidule za mlongoti wa FM transmitter ndikufotokozerani maupangiri 6 ogulira mlongoti wabwino kwambiri wa FM. Tiyeni tipitirize kufufuza!

Zomwe Muyenera Kudziwa Zokhudza FM Transmitter Antenna?

Kungophunzira za mlongoti wofalitsa ma wailesi ya FM kungakuthandizeni kumveketsa bwino dongosolo lakukweza ma wayilesi a FM chifukwa ndi chimodzi mwazinthu zofunika kwambiri zoulutsira mawu kuphatikiza ma transmitters a FM. Kenako, tiphunzira kuchokera pamagwiritsidwe ake ndi momwe zimagwirira ntchito.

Mapulogalamu - Mlongoti wa FM transmitter umagwiritsidwa ntchito powulutsa ma siginecha a FM omwe amanyamula zidziwitso zambiri, kuphatikiza mawu, zithunzi, zolemba, ndi zina zambiri. Chifukwa chake, mlongoti wowulutsa wa FM ungagwiritsidwe ntchito pawayilesi, mawayilesi a FM, ndi zina zambiri. Ali ndi mawonekedwe ndi makulidwe osiyanasiyana. mumapulogalamu osiyanasiyana owulutsa. 

Njira Zogwirira Ntchito - Mu njira yotumizira ma FM, chowulutsira mawayilesi a FM chimasintha ma siginecha amawu kukhala ma wayilesi a FM, kenako mlongoti wa FM umalandira ndikuwulutsa ngati ma siginecha a wailesi. Kuphatikiza apo, ngati mukufuna kuwulutsa ma siginecha mbali ndi mtunda wosiyanasiyana, mutha kuwaphatikiza kukhala makina a tinyanga a FM. 

Zonse, kuti musinthe ma wayilesi a FM, kumvetsetsa koyambira kwa antenna ya FM ndikofunikira, ndiye kuti mutha kukhala omveka bwino momwe mungasinthire ma siginecha a FM.

Maupangiri 6 Ogulira Mlongoti Wabwino Kwambiri wa FM Broadcast Transmitter

Sikophweka kumvetsetsa bwino za mlongoti wa FM. Mwamwayi, FMUSER ikufotokozera mwachidule maupangiri 6 ofunikira kwambiri ogulira mlongoti wabwino kwambiri wa FM. Ngakhale mutakhala novice, mutha kuzipanga mosavuta.

Dziwani Mitundu Yake

Kuonetsetsa kuti ndi mitundu yanji ya antenna yowulutsa ya FM yomwe mungafune kungakuthandizeni kusunga mtengo ndikuigwiritsa ntchito mokwanira. Mwachitsanzo, ngati mukufuna kuwulutsa mumzinda, muyenera kukhala ndi mlongoti wamphamvu ngati mlongoti wa FM yagi kuti muchepetse kusokonezedwa ndi kutsekeka kwa ma wayilesi a FM, pomwe mukamawulutsira kumidzi, mungafunike ma FM amnidirectional. ulutsa mlongoti ngati mlongoti wa dipole wa FM ndipo mudzakhala ndi kuwulutsa kwabwino.

Kuwulutsa ndi Full Frequency

Mlongoti wowulutsa wa FM womwe umagwirizana ndi ma frequency athunthu a FM utha kuthandizira ntchito zanu zowulutsa bwino. Mwachitsanzo, ngati pali ma siginecha akusokoneza pafupi, muyenera kusintha ma frequency osagwiritsidwa ntchito. Chifukwa chake, osati mawayilesi a FM okhawo omwe ayenera kukhala ndi ma frequency a FM, komanso mlongoti wa FM transmitter nawonso.

Tsimikizirani Njira Yotumizira 

Njira yopatsira yathunthu imaphatikizapo njira yopatsira ndi mtunda (womwe umadziwikanso kuti kupindula kwa mlongoti), ndipo uyenera kukhala wogwirizana ndi chilengedwe chanu komanso zomwe mukufuna kutumizira. Nthawi zambiri, ngati mukufuna kufalitsa ndi ngodya yotakata, phindu la mlongoti lingakhale locheperapo, ndipo zikutanthauza kuti mlongoti wanu wowulutsa umaphimba chophimba chaching'ono. Chifukwa chake, kudziwa njira yabwino yopatsira ndikofunika kwambiri, ndipo ndikulangizidwa kuti mufunsane ndi akatswiri a FM kuti akuthandizeni.

Sankhani Polarization Yoyenera

Polarization ingakhudze kuyankha kwa antenna a FM, zomwe zikutanthauza kuti zingakhudze zovuta zolandirira ma wayilesi. Nkhanizi zimachokera ku kuchuluka kwa kagwiritsidwe ntchito ka ma FM osiyanasiyana omwe amalandila tinyanga tosiyanasiyana, ndipo mlongoti woyima woyimirira wa FM womwe ukulandila ndiwo uli ndi kuchuluka kwakukulu. Chifukwa chake, kuti mupeze machesi abwino kwambiri ndi omwe alandila ma FM, ndikulangizidwa kuti musankhe mlongoti woyimirira wapolarized FM.

Onetsetsani Kuyika Kosavuta

Mlongoti wa FM transmitter wokhazikika mosavuta ungakhale wothandiza pomanga wayilesi ya FM ndi zida zina zofunika zowulutsira pawailesi ndikusamalira zida. Ndizofunikira osati ma novices a FM okha komanso akatswiri a FM, chifukwa palibe amene angafune kuwononga nthawi yawo pakuyika.

Khalani Okonzeka Ndi Ntchito Zathunthu Zachitetezo

Ntchito zotetezedwa zimatha kukulitsa moyo wautumiki ndikuchepetsa kutayika pamene mlongoti ukukumana ndi zoopsa zomwe sizikufuna. Monga mlongoti wa FM umayikidwa panja, uyenera kukhala ndi ntchito zamadzi, icing, chitetezo cha chinyezi.

Zomwe zili pamwambazi ndi maupangiri 6 osankha mlongoti wabwino kwambiri wa FM, ndipo tikukhulupirira kuti zikhala zothandiza pomanga wayilesi ya FM ndikukopa omvera ambiri. Monga m'modzi mwa opanga zabwino kwambiri za dipole antena za FM, FMUSER imatha kukupatsirani mitundu yosiyanasiyana ya tinyanga ta FM pazofuna zosiyanasiyana zotumizira pamitengo yabwino kwambiri. Ngati mukufuna, chonde omasuka kuti muwone!

Mafunso Ofunsidwa Kawirikawiri

1. Q: Momwe Mungawerengere Utali wa Mlongoti Wakuwulutsa kwa FM?

A: Mitundu yosiyanasiyana ya tinyanga zowulutsa za FM ili ndi njira zosiyanasiyana zowerengera.

Mwachitsanzo, ngati mukufuna kuwerengera kutalika kwa ma transmitter a theka-wave FM, mufunika fomula: L=v/(2*f), pomwe v imayimira kuthamanga kwa mafunde (~ 3x 10^8 m). /sec) ndi f imayimira ma frequency. Ndipo ngati mukufuna kuwerengera utali wa mlongoti wa dipole wa FM, mudzafunika fomula: L=468/f, pomwe f imayimira ma frequency.

2. Q: Kodi Mungasinthire Bwanji Zizindikiro Zanga za Wailesi Ya FM Moyenerera?

Yankho: Kuyika mlongoti wotumiza ma FM pamwamba ndi njira yabwino kwambiri yosinthira ma wayilesi a FM.

Mwambiri, pali njira zitatu zosinthira ma wayilesi a FM: Kuyika mlongoti wopatsira FM pamwamba, kusankha chowulutsira champhamvu kwambiri cha FM ndikusankha tinyanga zabwino kwambiri zoulutsira ma FM. Ndipo njira yoyamba imawononga ndalama zochepa ndipo imagwira ntchito bwino.

3. Q: Kodi chimachitika ndi chiyani ngati mutafalitsa popanda mlongoti wa FM?

A: Chowulutsira ma FM kapena chipangizo choyambira chingaphwanyidwe.

Mawayilesi a FM ndi mtundu wa mphamvu. Pamene chowulutsa cha FM chikuwulutsa, chimafunika kuchotsa mphamvu ku mlongoti wa FM. Ngati chowulutsira cha FM sichinalumikizidwe ndi mlongoti wa FM, mphamvu sizingasunthike, ndipo chowulutsira cha FM chitha kusweka mosavuta.

4. Q: Kodi Mlongoti Wanga wa FM Broadcast Antenna Ayenera Kugwiritsa Ntchito Motani?

A: Iyenera kuphimba ma frequency onse a FM, omwe ndi 65.8 MHz - 108.0 MHz.

Kwenikweni, pali magulu atatu afupipafupi a FM:

Gulu lodziwika bwino la FM: 87.5 - 108.0 MHz

Gulu lowulutsa la Japan FM: 76.0 - 95.0 MHz

Gulu la OIRT lomwe limagwiritsidwa ntchito kwambiri ku Eastern Europe: 65.8 - 74.0 MHz 

Kutsiliza

Kungomvetsetsa mlongoti wa FM transmitter ndikuphunzira momwe mungasankhire mlongoti wabwino kwambiri wa FM kungakhale kothandiza kwa inu kupititsa patsogolo kayendedwe ka wayilesi ya FM, kukupatsirani omvera ambiri ndikukulitsa bizinesi yanu yawayilesi.

Monga m'modzi mwa opanga zabwino kwambiri zoulutsira ma antenna a FM, FMUSER yapatsa makasitomala masauzande ambiri ma antenna apamwamba kwambiri a FM m'zaka makumi angapo zapitazi ndikukonzekera njira yabwino kwambiri ya tinyanga za FM kuti awapangire malingaliro.

Ngati mukufuna zambiri za mlongoti wa ma transmitter a FM kapena zidziwitso zina, chonde omasuka kulankhula nafe!
