Ndeipi tambo yeantenna yekusarudza uye yekutarisa kana uchitenga?

Iyo antenna kana coaxial tambo ine simba rakakura pamhando yechiratidzo uye nekudaro pamufananidzo unoratidzwa paTV. Saka zvakakodzera kutarisira sarudzo yakarurama yetambo. Chii chekutarisa kana uchitenga uye ndeipi tambo yeantenna yekusarudza?

Chii chinonzi antenna cable?

Basa rinonyanya kukosha retambo yeantenna ndeyekutapurirana-kusina kunetseka kwechiratidzo cheterevhizheni kubva kune mushambadziri, munyaya iyi, antenna, kune anogamuchira, i.e. TV. Cable yakanaka ichapa mufananidzo wehutano hwakanaka, saka ichava nemigumisiro chaiyo pahutano hwekugamuchira uye kufara kwekuona TV.

Kazhinji kazhinji, 2,5 GHz satellite cable inoshandiswa kune chinangwa ichi. Zvakare, iyo yakakamurwa kuva yakaonda uye yakakora shanduro, iyo inosiyana muhukuru hwekurwiswa kwemafungu, i.e. rudzi rwekudzivirira kwemagetsi. Izvi zvinokanganisawo kushandiswa kwetambo - 50-ohm shanduro dzinoshandiswa mumakombuta network uye redhiyo yekutaurirana tekinoroji, uye 75-ohm shanduro dzinoshandiswa seyekirasi terevhizheni mitsara.

Ini ndinoda antenna coaxial tambo?

Ehe, iyo antenna tambo inopa isingakanganiswe uye inoshanda yekugamuchira chiratidzo kubva kune inotapurirana. Izvi zvinokanganisa kwete chete mhando yemufananidzo, asiwo mashandiro eiyo yese RTV/SAT yekumisikidza. Saka, ngatizivei nezvezvinhu zvinokanganisa kunaka kwayo uye chinangwa, kuitira kuti tigone kutenga sarudzo inoenderana nezvido zvako. Nekuda kweizvozvo, iwe unogona kunakidzwa nemhando yemifananidzo isina kunaka uye kureba.

Chii chekutarisa kana uchitenga tambo?

Paunenge uchisarudza yakakodzera antenna tambo, teerera kune zvinotevera maficha:

• kureba kwetambo - gadzirisa kune chinhambwe pakati peantenna neTV, usakanganwa kuwedzera mashoma akakosha masendimita anodiwa pakuungana. Nekudaro, usatenge tambo yakarebesa "chero zvikaitika" - inowedzera njodzi yekukuvadzwa, inotaridzika isina kunaka uye inogona kukanganisa kunaka kwechiratidzo chinotapurwa;
• sheath zvinhu - iyo coaxial tambo iri kunze inofanirwa kuve neyakakora gobvu sheath yakagadzirwa neakasimba zvinhu. Muenzaniso wakagadzirirwa mukati unofanirwa kuchinjika kuitira kuti utakurwe zvisingaoneki, semuenzaniso pasi pekufukidzira;
• attenuation, kunyanya kukosha munyaya yetambo refu dzeantenna, inoderedza kunaka kwechiratidzo pamwe chete nechinhambwe kune anogamuchira. Zvinodikanwa kuti kukosha uku kuve kwakaderera sezvinobvira.
• kudzivirira kushanda zvakanaka - sei nhovo iri mukati metambo inodzivirira kubva mukukanganisika kana akati wandei marudzi etambo akaiswa padivi nepadivi.
• rudzi rwekurukwa - gobvu uye dense braid inobatsira kunyatso chengetedza iyo yakaitwa chiratidzo;
• musimboti mhando - gobvu musimboti wakagadzirwa neakanyanya conductive zvinhu unovimbisa yakaderera inogoneka attenuation uye yakanaka chiratidzo chiratidzo.

Ko tambo yeantenna inorongwa sei?

Rudzi urwu rwetambo inoumbwa nemateru akati wandei, imwe neimwe iine chinangwa chakasiyana. Heano maitiro ekugadzira eiyo coaxial tambo:

• mutsinga wemukati - chikamu chepakati, chiri munzvimbo yakadzika. Iyi itambo yemagetsi yakagadzirwa nemhangura kana mhangura-yakaputirwa simbi, inopa conductivity yakanaka;
• iyo yemukati insulating layer ndiyo inonzi dielectric yakagadzirwa nepurasitiki isina-conductive; inodzivirira uye inoparadzanisa musimboti;
• skrini - yakagadzirwa nealuminium kana mhangura foil;
• braid - mesh ine mhangura kana aluminium waya;
• kunze sheath - jira re polyethylene kana polyvinyl chloride kudzivirira tambo kubva kunze kwemaitiro. Kune zvakare LSFH shanduro uye Teflon coatings.

Cable zvinhu - ndeipi yekusarudza?

Iyo insulating zvinhu inoshandiswa kugadzira iyo inodzivirira layer inokanganisa kusimba uye usability yeiyo coaxial tambo. Semuenzaniso: mhando dzakagadzirwa nepolyethylene, i.e. yambotaurwa polyethylene, yakanakira kuisirwa kunze sezvo ichipokana nemamiriro ekunze senge mwando kana UV mwaranzi. PVC shanduro, i.e. polyvinyl chloride, yakanyanya elastic uye inochinjika, asi isinga shingirire kukuvara. Izvo zvakakodzera kuiswa kwemukati.

LSFH - kana Yakaderera Chiutsi Zero Halogen, chinhu chinoratidzwa nekubuda kwakaderera kwemagasi anokuvadza pakaitika moto unobvira. Inoshandiswa kuchengetedza tambo dzakaiswa kunze. Teflon kesi dzinodhura zvakanyanya, asi dzinopikisa zvakanyanya kushanduka kwekushisa (izvo zvakakosha zvakanyanya mumamiriro ekunze edu).

Kusarudzwa kwetambo uye rudzi rwe sheath zvinoenderana nenzvimbo uye mamiriro ayo achaiswa pasi.

Concentration - chii chimwe chinoshanda kune?

Antenna cable, i.e. hub, inobvumidza iwe kubatanidza inogamuchira kune yepasi terevhizheni, setiraiti, tambo uye vhidhiyo yekutarisa system. Inogona zvakare kushandiswa seA / V yekubatanidza tambo.

Maitiro ekubatanidza tambo yeantenna - zvimwe zvinhu kufambisa kuungana

Kana uchinetsekana nekuboora buri pamadziro kuti umhanye tambo panze, unogona kushandisa magirometi asingapindi mvura emahwindo, ayo akanakira kubatanidza tambo dzekunze kune dziri mukati. Havapindiri nekuvhara mahwindo kana magonhi, zvisingaoneki uye zvinogona kuchengetedza basa rakawanda.

Ndeipi tambo yeantenna yekusarudza - pfupiso

Iwe unotoziva kuti ndezvipi zvinhu zvekupa kutarisisa zvakanyanya paunenge uchifunga kutenga antenna tambo. Izvo zvakakosha, pakati pezvimwe zvinhu, kureba kwayo, zvinhu uye ukobvu hwejasi, kuderera kuderera uye kunyatsoita skrini. Yakanyatsosarudzwa antenna tambo yeTV inobvumidza iwe kuti uwane inogutsa yekubatanidza chiratidzo pasina kukanganisa. Izvo zvakakoshawo kubata nyanzvi yekuiswa kwehunyanzvi tambo pamba kuitira kudzivirira kukuvara kunogona kuitika.
