Ubwino ndi kuipa kwa zobisika mlongoti odana kuba

Kwa mankhwala odana ndi kuba, anthu ambiri amadziwa AM anti-kuba ndi mawayilesi odana ndi kuba.Awiriwa amagwiritsidwa ntchito kwambiri m'masitolo akuluakulu ndi zovala zotsutsana ndi kuba, koma anthu ochepa adamvapo za njira ina yotsutsa kuba yomwe inabisidwa mlongoti wotsutsa kuba.

Ndi imodzi mwazinthu zotsutsana ndi kuba za AM.Mafupipafupi omwe amagwiritsidwa ntchito ndi ma frequency a AM system, 58KHz.Dongosolo loletsa kuba ndi imodzi mwazinthu zodziwika bwino mu AM system, yokhala ndi chiwopsezo chachikulu komanso ntchito yokhazikika.Koma ilinso ndi zofooka zake.Poganizira kuti anthu ochepa amadziwa za tinyanga zobisika zobisika, lero ndikuwonetsani zabwino ndi zovuta zake.

1. Ubwino

1. Monga tafotokozera pamwambapa, kuchuluka kwa chidziwitso ndi ntchito ya chipangizo chobisika chobisika chotsutsana ndi kuba ndi bwino.Malingana ngati palibe vuto ndi chizindikiro chotsutsana ndi kuba, chiwerengero chake chodziwikiratu chikhoza kufika ku 99.5%, ndipo ntchito yake yotsutsana ndi kusokoneza ndi yabwino kuposa phokoso wamba ndi maginito Zida ziyenera kukhala zolimba komanso zokhazikika pa ntchito.

2. Ndi chipangizo chotsutsana ndi kuba chobisika mobisa.Simungachiwone chakutsogolo.Mlongoti wake umayikidwa pansi.Masitolo ena safuna makasitomala chifukwa cha malo apamwamba a malonda ndi malo osungiramo malo.Ngati mutha kuwona mlongoti wotsutsana ndi kuba, dongosolo loikidwa m'manda likhoza kuthetsa vutoli bwino.

3. Choletsa kuba ndi champhamvu.Akuba ena amawona kuti pakhomo la sitolo mulibe chipangizo choletsa kuba, ndipo chizindikirocho chimabisika.Amaganiza kuti sitoloyo ilibe zida zothana ndi kuba, motero amayesa kuba, koma amawululidwa pakhomo.Mkhalidwe wokhala ndi mbala udzakhala cholepheretsa, ndipo udzalepheretsanso anthu ena okhala ndi malingaliro akuba.

4. Ngakhale kuti sitolo yanu ndi yaikulu bwanji, ikhoza kukhala yotsutsana ndi kuba kumbali zonse.Ikhoza kuteteza kuba m'masitolo omwe ali ndi mtunda wautali wa khomo.Mutha kukhazikitsa mpaka 99 anti-kuba.Mlongoti woyima udzakhala wosawoneka bwino.

2. Kuipa

1. Zofunikira zapamwamba pazida.Mukayika chipangizo chotsutsana ndi kuba, chiyenera kuikidwa pamene sitolo ikukonzedwanso.Chifukwa imayenera kuikidwa pansi, iyenera kuikidwa musanayake pansi.Itha kukhazikitsidwanso pambuyo pokongoletsa, koma ndikofunikira kukweza matayala pansi kapena pansi, kotero kuyikako kumakhala kovuta komanso kuwononga nthawi.

2. Mtengo wake ndi wapamwamba kuposa wa zida wamba za AM.Ntchito yoletsa kuba yapansi panthaka ndi yabwino ndipo mtengo wake mwachilengedwe siwotsika.Ngati bajetiyo ikukumana ndi chiyembekezo ndipo khalidweli likutsimikiziridwa, akadali chisankho chabwino kusankha antenna yotsutsana ndi kuba ndi maginito pansi pa nthaka.
