1. Kutumiza kwa FM: chowulutsira cha FM chimawulutsa siginecha yamawu pamawayilesi. Imatembenuza siginecha yamawu kukhala RF (radio frequency) siginecha yovomerezedwa ndi mlongoti wowulutsa.

2. Njira yotumizira: Mzere wopatsira umayenda pakati pa chowulutsira cha FM ndi mlongoti wowulutsa, ndikutumiza mphamvu ya RF.

3. Chophatikiza RF: Chophatikizira cha RF chimagwiritsidwa ntchito ngati ma transmitters angapo a FM agawana mlongoti womwewo, kufananiza mphamvu zawo zotulutsa ndikuchepetsa zovuta zamakina.

4. Wokulitsa phokoso lochepa (LNA): Amagwiritsidwa ntchito kukulitsa chizindikiro cholandilidwa bwino komanso kuchepetsa phokoso.

5. Receiver kapena Tuner: Wolandila wailesi kapena chochunira wailesi amatha kulandira ndikusintha ma siginecha omwe amaperekedwa ndi mlongoti. Nthawi zambiri amagwiritsidwa ntchito powunika ndi kuyesa.

6. Zida Zosefera: Zida zosefera zimagwiritsidwa ntchito kuchotsa zizindikiro zosafunikira. Mwachitsanzo, zosefera za Band-pass zomwe zimachepetsa kuchuluka kwa ma frequency a siginecha kapena zosefera za notch zomwe zimapangidwa kuti zichotse zophatikizira zamtundu wina zomwe zingapangitse kusokoneza kosasangalatsa.

7. Chalk: Zida monga zingwe za coaxial, zolumikizira, zomangira, zida zoyatsira pansi, zomangira zowunikira, ndi ma antennae masts zitha kufunidwa kukhazikitsa, kutsitsa, ndi kuteteza dongosolo.

Mwa kuphatikiza zigawo zonse zofunika, dongosolo lathunthu la antenna a FM litha kupangidwa. Posankha makina amtundu wa antenna a FM, onetsetsani kuti zigawo zonse zimagwira ntchito bwino, zikugwirizana ndi zomwe mumakonda, ndikukwaniritsa zosowa zapadera za wayilesi.
Kodi ndingagwiritse ntchito antenna yowulutsa yamphamvu kwambiri ya FM potengera ma transmitter amphamvu a FM?
Mwaukadaulo, ndizotheka kugwiritsa ntchito antenna yowulutsa yamphamvu kwambiri ya FM pamagetsi otsika a FM. Komabe, sikungakhale njira yabwino kwambiri kapena yabwino kwambiri nthawi zonse. Nazi zina zomwe muyenera kukumbukira:

1. Kuchita bwino: Antenna yowulutsa yamphamvu kwambiri ya FM idapangidwa kuti izitha kutulutsa mphamvu zambiri kuchokera pa cholumikizira, kuwonetsetsa kuti imagwira ntchito bwino. Mukagwiritsidwa ntchito ndi mphamvu yochepetsera ma transmitter a FM, mphamvu yosagwiritsidwa ntchito / yochulukirapo pa mlongoti ingayambitse kusagwira bwino ntchito m'njira yowonetsera ma siginecha, kutayikira pafupipafupi komanso kuchepa kwa magwiridwe antchito a transmitter.

2. VSWR: Tinyanga zowulutsa zamphamvu kwambiri za FM zitha kukhala ndi VSWR (Voltage Standing Wave Ratio), yomwe imayimira kusamutsa mphamvu kuchokera pa chotumizira kupita ku mlongoti. VSWR yapamwamba sizodetsa nkhawa mukamagwira ntchito ndi cholumikizira champhamvu kwambiri koma imatha kukhala yowononga ngati ikugwiritsidwa ntchito ndi cholumikizira mphamvu chochepa. Kusagwirizana pakati pa chowulutsira ndi mlongoti wamphamvu kwambiri kungayambitse kuchepa kwa VSWR komwe kumapangitsa kuti mafunde oyima ndi kunyezimira mphamvu zomwe zingawononge kapena kuchepetsa moyo wa transmitter.

3. Kusagwirizana kwa mawonekedwe a radiation: Mlongoti wowulutsa wamphamvu kwambiri wa FM utha kukhala ndi mawonekedwe osiyana ndi omwe amafunikira ma transmitter. Kusiyana kwa ma radiation kungayambitse kusayenda bwino, chifukwa kufalikira kumatha kukhala kokulirapo kapena kuchepera pomwe pakufunika.

4. Mtengo: Mlongoti wamagetsi wamphamvu kwambiri wa FM nthawi zambiri umakhala wokwera mtengo kuposa wamagetsi otsika. Kukwera mtengo kumeneku kungakhale kosafunikira, makamaka ngati chowulutsira champhamvu chotsika cha FM sichifuna kuchuluka kwamphamvu kapena ngati pali zovuta za bajeti pomwe njira zina zotsika mtengo zimatha kukwaniritsa zofunika.

Nthawi zambiri, kugwiritsa ntchito antenna yotsika yamagetsi yamagetsi ya FM yopangidwira mphamvu yotumizira imalimbikitsidwa kuti zitsimikizire kuyendetsa bwino kwadongosolo, kusunga chiyerekezo chabwino cha VSWR ndi mawonekedwe a radiation omwe amagwirizana ndi zomwe wailesiyi ikufuna. Zigawo zadongosolo zimapangidwira kuti zizigwira ntchito pamagulu apadera a mphamvu, ndipo chisamaliro chiyenera kutengedwa kuti chitsimikizidwe kuti chigawo chilichonse chikugwiritsidwa ntchito molingana ndi ndondomeko ya mapangidwe kuti zitsimikizire kugwira ntchito bwino, moyo wautali, ndi kudalirika kwa dongosolo lonse.
Kodi ndingagwiritse ntchito antenna yotsika yamphamvu ya FM pa chowulutsira champhamvu kwambiri cha FM?
Ayi, sizovomerezeka kugwiritsa ntchito mlongoti wamagetsi otsika wa FM wokhala ndi chowulutsira champhamvu cha FM. Mlongoti ndi chingwe chotumizira ziyenera kupangidwa kuti zizitha kutulutsa mphamvu zambiri za chowulutsira cha FM kuti zipewe kuwonongeka kapena kuwonongeka kwa magwiridwe antchito.

Kugwiritsa ntchito antenna yotsika yamphamvu ya FM pamagetsi apamwamba a FM kungayambitse:

1. Mavuto a VSWR: Mlongoti wamagetsi otsika kwambiri wa FM sungakhale wopangidwa kuti uzitha kutulutsa mphamvu yamagetsi okulirapo ndipo ukhoza kubweretsa kuchuluka kwa VSWR. Kulephera kumeneku kungayambitse kuwunikira mphamvu, kutsika kwamtundu, komanso kutsika kwa siginecha yanu yowulutsira.

2. Kutentha ndi kuwonongeka: Zolumikizira za mlongoti, chingwe chotumizira ndi ma radiation amatha kutenthedwa komanso kusungunuka kapena kuwonongeka ngati mphamvu yotulutsa yopitilira muyeso ipitilira, zomwe zitha kukhala zowopsa ku dongosolo.

3. Kuchepetsa kulimba: Mlongoti wamagetsi otsika kwambiri a FM ukhoza kupangidwa ndi zida zotsika komanso zinthu zochepa kuposa tinyanga tamphamvu kwambiri zomwe zimapangidwira kuti zizigwira ntchito zamphamvu kwambiri komanso kulimba kwanthawi yayitali.

4. Opaleshoni yosagwirizana: Kudzaza tinyanga kungapangitse woyendetsa wailesiyi kuti asagwirizane ndi malamulo adziko lonse kapena chigawo, motero, kumabweretsa zotsatirapo zamalamulo.

Chifukwa chake, ndikofunikira kusankha antenna yowulutsa ya FM yomwe idapangidwa makamaka kuti ipangitse mphamvu ya transmitter. Mlongoti wamagetsi wapamwamba kwambiri udzakhala ndi chiŵerengero chokwanira cha VSWR chogwiritsira ntchito mphamvu yotulutsa ma transmitter, motero kufalitsa kothandiza popanda kuwonongeka kwa zida zotumizira kapena nkhani zabwino. Yang'anani zomwe wopanga akupanga, mapangidwe ake, ndi zofunikira zoyika zida zanu zotumizira ndi mlongoti musanasankhe zofananira bwino kuti zigwire bwino ntchito komanso kukwanilitsa zofunikira pakuwongolera.
