Monga nthambi ya antena, magalimoto antenna ali ndi ntchito yofananira ndi antennas ena, ndipo adzakumana ndi mavuto ngati amenewa.
1. Choyamba, ubale womwe ulipo pakati pa malo ophatikizira a mgalimoto antenna ndi chizolowezi chake?
Mu lingaliro, galimoto yomwe antenna idakhazikitsidwa pagalimoto ilibe njira yolowera mopingasa, koma chifukwa cha mawonekedwe osakhazikika a mmalo a mgalimoto ndi mawonekedwe a mafoni Umodzi uwu ndi wosiyana ndi anteri yoyenda. Kuwongolera kwa ma antennas galimoto kumakhala kosiyanasiyana komanso kumasiyana mgalimoto kupita pagalimoto.
Ngati antenna idayikidwa pakati pa denga la nyemba Ngati antenna akhazikika mbali imodzi, zotsatira za radiation ndizobwino pang'ono. Chifukwa chake, nthawi zina timapeza kuti tikamapita njira yomweyo, zotsatirapo zoyankhulirana zili bwino, koma titabwereranso, zomwe zimayankhulana molunjika ndizosiyana kwambiri, chifukwa ku Antenna kumeza mbali zonse zagalimoto ndizosiyana.
2. Chifukwa chiyani zizindikiro za kulumikizana mwachindunji mu kugwiritsa ntchito V / UHF Mobile?
Nthawi zambiri, mafunde a V / UHF Freency ali ndi njira zingapo pofalitsa, ena amapeza malo olandirira pamzere wowongoka, ndipo ena amapeza podikira. Mphepoyo ikadutsa pamtengo wachidule ndikuwonetsa kuti mafunde ali mgawo lomwelo, mafunde awiriwo amathandizira kulimbitsa mphamvu kwa mphamvu ya chizindikiro. Mafunde mwachindunji ndi owonetsedwa atadutsa m'magawo motsutsana, zopatsa mphamvu zawo zimaletsana. Pomwe mtunda pakati pa kutumiza ndi kulandira wa radio yagalimoto nthawi zonse ikamasuntha, yomwe imawoneka bwino kwambiri, yomwe imawonetsedwa pazizindikiro zina.
Ndi liwiro losiyanasiyana, nthawi yosinthasintha kusintha kwayilesi ndikosiyananso. Lamulo la kusintha ndi: Bukuli lapamwamba la ntchito, lalifupi kwambiri, liwiro loyenda, limakwera pafupipafupi chizindikiro. Chifukwa chake, pamene kukana kwa chizindikiro chachikulu kumakhudza kulumikizana, mutha kuchepetsa liwiro loyenda, pezani malo omwe chizindikiro chapamwamba ndi champhamvu kwambiri, chotsani galimotoyo kuti igwirizane mwachindunji, kenako ndikubwerera mumsewu.
3. Kukhazikitsa kwa Antertna Kukhazikika kapena kukhazikitsa kwa Oblique kuli bwino?
Magalimoto ambiri amagwiritsa ntchito anternas a anternas pazifukwa zotsatirazi: Choyamba ndichakuti antetna mogwirizana ndi njira yolowera mosamala, kotero kuti wayilesi yamagalimoto mu mafoni sayenera kuvutitsa kugwirizanitsa njira ya antenna; Chachiwiri, anternal anterna amatha kugwiritsa ntchito chipolopolo chachitsulo ngati oscillator wake, kotero kuti pamene pamene pamene okhazikika anterna akugwiritsa ntchito, theka lokhalo litha kukhazikitsidwa, ndipo theka lokhalo litha kukhazikitsidwa, ndipo zotsalazo zitha kusinthidwa ndi thupi lagalimoto, lomwe silimangochepetsa thupi Mtengo, komanso umathandizira kukhazikitsa ndikugwiritsa ntchito. Wachitatu ndikuti anternal anterna amakhala ochepa, ndipo kukana kwa mchenga ndi yaying'ono, komwe kumatha kuyenda mwachangu.
Kuchokera pamenepa, gawo lomwe takhazikitsayo ndi theka la manternal antetal. Chifukwa chake, pamene antenna itakhazikika mbali imodzi, mafunde ailesi omwe amapezeka ndi antenna sakhala mafunde okhazikika, koma osakanikirana a mafunde okhazikika komanso opingasa. Ngati kulandira antering mbali inayo kumalandira mafunde okhazikika, mphamvu ya chiwonetsero cha chivomerezi imachepetsedwa (yopanda polarization yopingasa), ndipo mosemphana ndi chizindikiro cha omwe adalandira. Kuphatikiza apo, antenna otsatsa amachititsa kuti ma radiation osasamala, omwe amawonetsedwa ngati kutsogolo kwa antenna ndi akulu kuposa odzikuza, omwe amabweretsa ku chiwongola dzanja.
4. Kodi mungathetse bwanji zosemphana ndi phokoso zomwe zimabweretsedwa ndi galimoto intenna mukalandira zizindikiro?
Kusokoneza kwa antenna phokoso kumagawika pakusokoneza kwapakatikati komanso mitundu iwiri. Kusokonezedwa ndi kunja ndi chizindikiro chomwe chimakhudzidwa ndi anterna kunja kwagalimoto, monga kulowerera kwa masitima, njira yosokoneza bongo yosokoneza bongo, njira yabwino kwambiri yopewera kusokonekera. Nthawi zambiri, FM mode in V / UHF Band ali ndi mphamvu yolimbana ndi kusokonekera kwamtunduwu. Chizindikiro chitatsegulidwa, kufooka kwa makinawo kungathetse zosokoneza. Pofuna kulowerera mkati, mutha kumangoyesa ndikumvetsera kwa adilesi yofooka. Ngati kusokonezedwa sikwakukulu, zikuwonetsa kuti palibe vuto ndi kulowerera kwa galimoto. Ngati pali zosokoneza zina zamkati, kugwiritsa ntchito transceiver kumathetsa mavuto ambiri.
