Amplifier yeTV antenna

Muzera redu teknolojia, mhuri manheru paTV inopera zvishoma nezvishoma munguva yakapfuura. Asi kunyange nhasi kune vanhu vakawanda TV inoramba iine zindo chete munyika uye nzira yekusiyanisa nguva yavo yekuzorora. Uye ndedzipi dzakaipa dzisina kunaka dzinokonzerwa nehurombo-huterevhizheni mifananidzo - yakasvibiswa, ichikwira, ichiputika mumapiksesi ega ... Muzviitiko zvizhinji, matambudziko aya anobatwa zvakajeka - kutenga chidimbu chakakosha cheAntenna TV. Munzira yekusarudza nekuisa chigadziridziro cheAntenna yeTV , ngativei kuifunga pamwe chete.

Nzira yekusarudza yakagadzirisa sei antenna TV?

Mumusika wezuva ranhasi, pane dzakawanda zvakasiyana-siyana zvevhidhiyo dzakasiyana-siyana dzeTV dzinotanga kuona kuti zvakaoma kusarudza kuti ndeipi iyo yakakodzera pane imwe nyaya. Zvechokwadi, zvinhu zvose zviri nyore kwazvo - kuitira sarudzo yakarurama zvakakwana kuti uzive zvishoma maseraji:

1. Nharaunda yakatarisa iyo nzvimbo iri pedyo iyo inotumira chiratidzo cheterevhizheni. Zvichienderana nehanzvadzi iyi, kukudziridza chikonzero chemugadziri wechirongwa chinosarudzwa. Iyo yakareba kure nechiteshi chekuendesa inogona kunge yakagadzirirwa 150 km. Nechidimbu chemasita anodarika 10 km, iyo amplifier haifaniri zvachose - zvakakwana kusarudza TV yakakodzera antenna. Zvakaipa zvachose "kuva nemakaro" uye kutenga chikwata, nechimwe chinhu chakakwirira kudarika zvakakosha - zviyero zvakadaro zvine pfuma yekuzvidzora uye panzvimbo yemufananidzo wakaisvonaka, pakupedzisira, kungopindira kwongowanikwa chete.
2. Nhamba yezvidimbu iyo chiratidzo chacho inoparidzirwa imamita, decimeter, nezvimwe. Chinhu chakanaka chegadziriro chero ipi zvayo ichave kuiswa kwekuwedzera kwebandaneti kumusana wepasi rose anokwanisa kugamuchira mazai epi zvayo. Asi chikonzero chakanaka zvikuru chichawanikwa kuburikidza nekuisa shoma-bandimiridziro inoshanda mune imwe nzvimbo.
3. Rudzi rwekuiswa TV antenna. Somuenzaniso, pane terevhizheni antennas we type trellis, chiratidzo chacho chinokurudzirwa nekubatsirwa kwe swa swa amplifiers anoshandiswa mukati me 49-790 MHz. Asi aya anonyanya kuzivikanwa kunze kweTV Locus anoshanda zvakanaka neLSA amplifiers.
4. Kana ukasarudza zvakakosha kuteerera kutinhira kwemugadzirimu - zviduku iyi parameter, zviri nani mufananidzo unozopedzisira wava paTV.

Ndingaisa sei antenna amplifier yeTV?

Kuiswa kwemazuva ano emagetsi emagetsi ekutenderera antenna yakajeka zvokuti kunyange munhu zvachose ari kure neredhijini inogona kuzviita. Simba rine simba rinoendeswa kumugadziridziri, kuburikidza naro izvo zvigadziridziro zvakabatanidzwa kumagetsi ekugadzirisa. Simba rekushandisa kwechigadzirwa chakadaro chiduku zvikuru uye kazhinji kechirongwa che 10 W. Paunenge uisa iyo amplifier zvakananga pane antenna, dhigiriji yemawindo inoshandiswa kuburikidza nekashandisi yakagadzirisa adapta. Paunenge uchishandisa chidimbu chakafanana, iyo amplifier inogamuchira simba zvakananga pamusoro pekanda coaxial, pamwe chete nechitarisiko cheterevhizheni. Izvi zvinogadzirisa zvinhu zviviri: imwe inobatanidza kambo kubva paTV antenna, uye imwe yakabuda inosanganiswa ne connector ye antenna yeTV, asi iyo adapta inobatana neimba yeimba.

Paunosarudza nzvimbo yekuisa chigadziro chechigodhi che antenna, rangarira kuti iri pedyo neantenna, zviri nani zviratidzo zvichave. Muchiitiko ichi, chigadziro chinofanira kunge chakachengetedzwa zvakavimbika kubva kune simba rekumhanya kwepasi. Mukana wekushandisa antenna dzomukati neyekusimudzira terevhizheni, iyo yekupedzisira inogona kuiswa kana zvakananga pane antenna kana kuti pfupi pairi.
