Toetoetra:
- Broad Band
- Ny mari-pana ambany tabataba
- Low Input VSWR
Amin'ny rafi-pifandraisana, mba hanamora ny fifindran'ny famantarana sy hahatratrarana ny fampiasana indray ny fantsona, dia avo be ny fatran'ny famantarana alefa, noho izany dia lafiny manan-danja amin'ny fikarohana momba ny rafi-pifandraisana. Araka ny toe-javatra mialoha sy aorian'ny fiovam-po matetika, dia azo zaraina ho ambany fiovam-po (frequency fampihenana) sy ny ambony fiovam-po (fampitomboana matetika).
Ao amin'ny mpandray, raha ambany noho ny famantarana tany am-boalohany ny mari-pandrefesana mahazatra azo aorian'ny fampifangaroana, dia antsoina hoe block downconverters (LNBs) ity fomba fampifangaroana ity.
Ny fomba fampihenana ny sakana dia ny fampitomboana ny mari-pamantarana azo amin'ny famantarana oscillator eo an-toerana novokarin'ny oscillator eo an-toerana, ary avy eo dia mahazo ny famantarana niova fo amin'ny alàlan'ny sivana ambany. Ny famantarana roa ampitomboina dia azo zaraina ho fampifangaroana tena izy sy fampifangaroana sarotra amin'ny alàlan'ny fanehoana tena izy na sarotra.
Ny tanjon'ny block downconverters dia ny fampihenana ny fatran'ny mpitatitra ny famantarana na ny fanesorana mivantana ny fatran'ny mpitatitra mba hahazoana ny famantarana baseband. Noho ny fizaran-tany tsotra sy ny vidiny ambany, ny fomba fiovam-po midina dia ampiasaina betsaka amin'ny fitaovana sivily sy fitaovana miaramila miaraka amin'ny fepetra takiana ambany.
1. Televiziona zanabolana: LNB dia singa fototra amin'ny rafitra fandraisana TV amin'ny zanabolana. Izy ireo dia apetraka eo amin'ny toerana ifantohan'ny antenna zanabolana (paraboloida na lovia), mandray ny famantarana amin'ny fahitalavitra ampitaina amin'ny zanabolana, ary mamadika izany ho famantarana fanelanelanana mpanelanelana izay azon'ny mpandray.
2. Aterineto zanabolana: Amin'ny rafitra Aterineto amin'ny zanabolana, ny LNB dia ampiasaina handraisana angona amin'ny Internet ampitaina amin'ny zanabolana. Ny fitaovan'ny mpampiasa dia mandray ny angon-drakitra amin'ny alàlan'ny LNB ary mamadika sy manodina azy amin'ny modem.
3. Fifandraisana amin'ny zanabolana: Ny LNB dia ampiasaina betsaka amin'ny rafitra fifandraisana amin'ny zanabolana isan-karazany, anisan'izany ny telefaona zanabolana, fampitana zanabolana, fampitana angon-drakitra amin'ny zanabolana, sns.
4. Fanaraha-maso ny Tany sy Fandrefesana Lavitra: Amin'ny fampiharana fanaraha-maso ny tany sy fandrefesana lavitra, ny LNB dia ampiasaina handraisana angon-drakitra fandrefesana lavitra alefa avy amin'ny zanabolana. Ireo angona ireo dia azo ampiasaina amin'ny fanaraha-maso ny toetr'andro, ny fanaraha-maso ny tontolo iainana, ny fampitandremana ny loza ary ny sehatra hafa.
Raha fintinina, ny LNB dia mitana anjara toerana lehibe amin'ny rafitra fifandraisana amin'ny zanabolana maoderina ary ampiasaina betsaka amin'ny fampielezam-peo, fidirana amin'ny Internet, fifandraisana data ary sehatra matihanina isan-karazany.
Qualwavemanome karazana Block Downconverters (LNBs) isan-karazany ao amin'ny S~Ka-Band, miaraka amin'ny mari-pana 45~240K. Ny famaranana miaraka amin'ny karazana samihafa mba hanomezana ny filan'ny mpanjifa.
