Mlongoti wawayilesi ya FM ndi imodzi mwazinthu zofunika kwambiri komanso zokwera mtengo zotumizira pawayilesi yanu ya FM. Itha kukupulumutsirani nthawi yochulukirapo komanso khama komanso ndalama zokonzetsera ngati mutha kusankha antenna yokhazikika ya FM yogwira ntchito bwino.

Ndikofunikira kwambiri, makamaka kwa oyamba kumene a RF. Komabe, amafunikira kalozera wogulira kuti awathandize kusefa zidziwitso zofunika kwambiri zogulira za mlongoti wa FM. 

Mwamwayi, tikukupatsani malangizo 6 ofunikira kwambiri ogula kuti muzindikire, kukuthandizani kugula mlongoti wa wayilesi ya FM pamitengo yabwino kwambiri. Tiyeni tiyambe!

mitundu

Muyenera kusankha mtundu wabwino kwambiri wa tinyanga towulutsa ma FM okhala ndi mawonekedwe osiyanasiyana kutengera ntchito zosiyanasiyana. Nthawi zambiri, tinyanga ta ma transmitter a FM amabwera m'mitundu yodziwika bwino iyi:

• Monopole FM mlongoti - Zimagwira ntchito bwino pazigawo zopapatiza ndipo zimatha kutha. Nthawi zambiri amagwiritsidwa ntchito pamagetsi otsika a FM wailesi ndi magalimoto.

• Dipole FM mlongoti - Ndi imodzi mwamitundu yodziwika kwambiri yomwe imagwiritsidwa ntchito mu tinyanga ta wayilesi ya FM. Ili ndi bandi yayikulu ndipo imatha kuwunikira mbali zonse.

• Yagi FM antenna - Mlongoti wa Yagi ndi mtundu wa mlongoti wopindula kwambiri. Ndi yabwino kwa mapulogalamu omwe amafunikira njira yayitali yotumizira ma siginecha a wayilesi, monga Studio Transmitter Link yomwe ikufunika kufalitsa mtunda wautali.

• Mlongoti wozungulira polarized - Zimalola kuti tinyanga tating'ono tomwe timalandira molunjika komanso mopingasa kuti tizilandira ma wayilesi.

Malangizo

Zoonadi, mayendedwe ndi ofunika kwambiri. Muyenera kudziwa bwino cholinga cha wayilesi yanu ya FM.

Ngati mukufuna kufalitsa mapulogalamu anu owulutsa pawailesi kwa omvera ozungulira, ndiye kuti mungafunike mlongoti wa omnidirectional, monga dipole FM antenna, kapena kuphatikiza ma antenna angapo owulutsa a FM palimodzi.

Ndipo ngati wayilesi yanu ya FM ikugwiritsidwa ntchito kufalitsa ma wayilesi mbali imodzi ngati Studio Transmitter Link, ndiye kuti palibe kukayika kuti mufunika mlongoti wa wayilesi ya FM, monga mlongoti wa Yagi FM.

phindu

Kupindula kwakukulu kumatanthauza kuti mlongoti wanu wa wailesi ya FM umayang'ana mawayilesi pamalo ocheperako, zomwe zimatsogolera ku mphamvu yamphamvu ya wailesi. Zimatanthawuzanso kuti kupindula ndi mayendedwe amalumikizana, ndipo kuwonjezereka kowonjezereka kumatha kupereka ma radiation angapo.

Pali njira zambiri zopezera phindu, monga kuchulukitsa tinyanga tawayilesi za FM kapena kuwasintha ndi tinyanga tawayilesi za FM ndikupeza phindu lalikulu. Zimatengera mawonekedwe a ma wayilesi amawayilesi omwe mukufuna.

bandiwifi

Pankhani ya bandwidth, pali mitundu iwiri ya tinyanga: wide band FM antenna and tuned FM antenna.

Ma antennas amtundu wa FM ali ndi bandwidth yokhazikika pafupifupi 20MHz ndipo amagwira ntchito bwino mu 20MHz yonse ya gulu la FM. Ndipo imatha kugwira ntchito bwino mu bandwidth.

Ma Antennas a Tuned FM amasinthidwa kukhala kagulu kakang'ono kokha mozungulira ma frequency omwe adasinthidwa. Ndipo sizingagwire ntchito kusunga magwiridwe omwewo mu bandwidth.

Ma antennas a Broadband FM nthawi zonse amakhala okonda kusinthidwa ngakhale atakhala okwera mtengo.

Kugawanika

Polarization imatanthawuza komwe kumayendera ma elekitiromagineti opangidwa ndi mlongoti wa wayilesi ya FM, ndipo imagawidwa kukhala polarization yoyima komanso yopingasa. Mayendedwe a polarization a mlongoti wolandira ndi mlongoti wotumizira ayenera kufananizidwa kuti athe kulumikizana bwino. Choncho, kusankha polarization kumadalira mmene zinthu zilili m'deralo.

Ngati simukudziwa kuti polarization ndiyo yabwino, mutha kusankha mlongoti wozungulira wozungulira, womwe uli ndi polarization yowongoka komanso polarization yopingasa, koma cholandirira ndi mlongoti wolandila chidzachepetsedwa ndi theka, chifukwa mphamvu yamawu a wailesi idzagawidwa mofanana. mbali ziwiri.

opanga

Mtundu wabwino kwambiri ukhoza kutsimikizira zamtengo wapatali wazinthu zawo, monga FMUSER, osati zokhazo, mutha kupezanso mautumiki awo ndi zinthu zabwino kwambiri pamtengo wokwanira, kuchepetsa kugula kwanu ndi ndalama zina ndikukulolani kuti muyang'ane kwambiri Ntchito ya wailesi ya FM.

Kutsiliza

Tiyeni tifotokoze mwachidule momwe tingasankhire mlongoti wabwino kwambiri wa wayilesi ya FM:

• mitundu - Sankhani mitundu yosiyanasiyana ya antenna yowulutsa ma FM malinga ndi momwe mungagwiritsire ntchito
• Malangizo - Zimatengera cholinga chotumizira chizindikiro.
• phindu - Zimatengera mawonekedwe a wailesi omwe mukufuna.
• bandiwifi - Kutalikirako kumakhalako bwino, momwe mungathere ndi chizindikiro cha FM.
• Kugawanika - Onetsetsani kuti mawayilesi atha kulandira bwino pulogalamu yanu yowulutsira.

Kutengera maupangiri 6 ogula awa, ngakhale mutakhala oyambitsa RF, mutha kupeza antenna yabwino kwambiri yawayilesi ya FM, ndikusintha ma wayilesi kuti akhale abwino kwambiri.

Ngati mukufuna kudziwa zambiri za tinyanga ta wayilesi ya FM, chonde omasuka kulumikizanani ndi FMUSER!
