    Paraka Whakararo (LNB)

    I roto i nga punaha whakawhitiwhiti korero, kia pai ai te tuku tohu me te whakatutuki i te whakamahi ano i te hongere, he tino tiketike te auau o nga tohu tuku, na reira ko te huringa auau o nga tohu he waahanga nui o te rangahau punaha korero. E ai ki te ahuatanga i mua i muri i muri i te huringa auau, ka taea te wehea ki raro (te whakaheke tere) me te piki ake (te pikinga o te auau).
    I roto i te kaikawe, mena he iti ake te tohu auau takawaenga i muri mai i te whakaranu i te tohu taketake, ka kiia tenei tikanga whakaranu he poraka whakaheke (LNBs).
    Ko te tikanga o nga kaitahuri whakaheke poraka ko te whakanui i te tohu kua riro mai me te tohu oscillator rohe i hangaia e te oscillator o te rohe, katahi ka whiwhi i te tohu whakawhiti ma te tātari iti-paahi. Ka taea te wehea nga tohu whakarea e rua ki te ranu tuturu me te ranu matatini ma te tohu tuuturu, uaua ranei.
    Ko te kaupapa o nga kaihuri whakaheke poraka ko te whakaiti i te auau kawe o te tohu, te tango tika ranei i te auau kawe ki te whiwhi i te tohu turanga. Na tona ara iahiko ngawari me te iti o te utu, ka whakamahia te tikanga whakawhiti ki raro ki nga taputapu a-iwi me nga taputapu hoia me nga whakaritenga mahi iti.

    Taupānga:

    1. TV Satellite: Ko nga LNB nga waahanga matua i roto i nga punaha tango pouaka whakaata amiorangi. Ka whakauruhia ki te waahi o te antenna amiorangi (paraboloid, rihi ranei), ka whiwhi i te tohu pouaka whakaata e tukuna ana e te amiorangi, ka huri hei tohu auau takawaenga ka taea e te kaiwhiwhi te whakahaere.
    2. Ipurangi Satellite: I roto i nga punaha Ipurangi amiorangi, ka whakamahia nga LNB ki te whiwhi raraunga Ipurangi ka tukuna mai i nga amiorangi. Ka whiwhi nga taputapu kaiwhakamahi i nga raraunga ma te LNB me te wetewete me te tukatuka ma te pouwhanga.
    3. Whakawhitiwhiti Whakawhitiwhiti: Kei te whakamahia nuitia nga LNB i roto i nga momo punaha korero amiorangi, tae atu ki nga waea amiorangi, nga haapurorotanga amiorangi, te tuku raraunga amiorangi, me etahi atu.
    4. Te Tirohanga Whenua me te Maataki Mamao: I etahi tono tirohanga mo te whenua me te whakamaarama mamao, ka whakamahia nga LNB ki te tango i nga raraunga tairongo mamao ka tukuna mai i nga amiorangi. Ka taea te whakamahi i enei raraunga i roto i te aroturuki meteorological, te aroturuki i te taiao, te whakatupato kino me etahi atu mara.
    Hei whakarāpopototanga, ka whai wāhi nui nga LNB ki roto i nga punaha korero amiorangi hou, ka whakamahia nuitia i roto i te whakaata pouaka whakaata, te uru Ipurangi, te whakawhitiwhiti raraunga me nga momo mara ngaio.

    Ngarurangihe maha nga momo Poraka Whakahurihuri (LNB) i roto i te S~Ka-Band, me te pāmahana haruru o te 45~240K. Ko nga whakamutu me nga momo rereke hei whakatutuki i nga hiahia o nga kaihoko.
