Nā mea hoʻololi poloka (LNB)

I loko o nā ʻōnaehana kamaʻilio, i mea e maʻalahi ai ka hoʻoili ʻana i nā hōʻailona a hoʻokō i ka hoʻohana hou ʻana i ke kahawai, kiʻekiʻe loa ke alapine (frequency) o nā hōʻailona i hoʻouna ʻia, no laila he mea nui ka hoʻololi pinepine ʻana o nā hōʻailona i ka noiʻi ʻōnaehana kamaʻilio. Wahi a ke kūlana ma mua a ma hope o ka hoʻololi pinepine ʻana, hiki ke hoʻokaʻawale ʻia i ka hoʻololi i lalo (ka hoʻemi pinepine ʻana) a me ka hoʻololi i luna (ka hoʻonui pinepine ʻana).
I loko o ka mea hoʻokipa, inā ʻoi aku ka haʻahaʻa o ka hōʻailona alapine waena i loaʻa ma hope o ke kāwili ʻana ma mua o ka hōʻailona mua, a laila ua kapa ʻia kēia ʻano kāwili ʻana he block downconverters (LNBs).
ʻO ke ʻano o nā block downconverters, ʻo ia ke hoʻonui i ka hōʻailona i loaʻa me ka hōʻailona oscillator kūloko i hana ʻia e ka oscillator kūloko, a laila loaʻa ka hōʻailona i hoʻololi ʻia ma o kahi kānana haʻahaʻa. Hiki ke hoʻokaʻawale ʻia nā hōʻailona ʻelua i hoʻonui ʻia i ka hui maoli a me ka hui paʻakikī ma o ka hōʻike maoli a paʻakikī paha.
ʻO ke kumu o nā block downconverters, ʻo ia ke hoʻemi i ke alapine lawe o ka hōʻailona a wehe pololei paha i ke alapine lawe e loaʻa ai ka hōʻailona baseband. Ma muli o kona kaapuni maʻalahi a me ke kumukūʻai haʻahaʻa, hoʻohana nui ʻia ke ʻano hoʻololi iho i nā lako kīwila a me nā lako koa me nā koi hana haʻahaʻa.

Noi:

1. Ke kīwī ukali: ʻO nā LNB nā ʻāpana koʻikoʻi i nā ʻōnaehana hoʻokipa kīwī ukali. Hoʻokomo ʻia lākou ma ke kiko kikowaena o kahi antenna ukali (paraboloid a i ʻole kīʻaha), loaʻa ka hōʻailona TV i hoʻouna ʻia e ka ukali, a hoʻololi iā ia i hōʻailona alapine waena e hiki ke hana ʻia e ka mea hoʻokipa.
2. Pūnaewele Ukali: Ma nā ʻōnaehana Pūnaewele Ukali, hoʻohana ʻia nā amplifiers e loaʻa ka ʻikepili Pūnaewele i hoʻouna ʻia mai nā satelite. Loaʻa i nā lako mea hoʻohana ka ʻikepili ma o ka LNB a wehewehe a hana iā ia ma o ka modem.
3. Nā Kamaʻilio Ukali: Hoʻohana nui ʻia nā mea hoʻonui RF i nā ʻōnaehana kamaʻilio ukali like ʻole, me nā kelepona ukali, nā hoʻolaha ukali, ka hoʻouna ʻikepili ukali, a me nā mea ʻē aʻe. Kōkua lākou i ka loaʻa a me ka hana ʻana i nā ʻano hōʻailona kamaʻilio like ʻole i hoʻouna ʻia mai nā ukali.
4. Nānā Honua a me ka ʻIke Mamao: Ma kekahi mau noi nānā Honua a me ka ʻike mamao, hoʻohana ʻia nā mea hoʻonui microwave e loaʻa i ka ʻikepili ʻike mamao i hoʻouna ʻia mai nā satelite. Hiki ke hoʻohana ʻia kēia mau ʻikepili i ka nānā ʻana i ka meteorological, ka nānā ʻana i ke kaiapuni, ka ʻōlelo aʻo pōʻino a me nā ʻoihana ʻē aʻe.
I ka hōʻuluʻulu manaʻo, he kuleana koʻikoʻi ko nā LNB i nā ʻōnaehana kamaʻilio ukali hou a hoʻohana nui ʻia i ka hoʻolaha kīwī, ke komo ʻana i ka Pūnaewele, ka kamaʻilio ʻikepili a me nā ʻoihana like ʻole.

Qualwavehoʻolako i nā ʻano like ʻole o nā Block Downconverters (LNBs) ma ka S~Ka-Band, me ka mahana walaʻau o 45~240K. ʻO nā hoʻopau me nā ʻano like ʻole e hoʻokō i nā pono o nā mea kūʻai aku.
