Ke piʻi nei ka koi o nā ʻōnaehana kamaʻilio broadband ma nā ʻano pae like ʻole o nā paepae lawe lima, e laʻa me nā moku moana, nā kaʻa ʻāina a me nā mokulele. Hoʻonohonoho ʻia kēlā me kēia meahana mua me hoʻokahi a ʻoi paha nā radar, a he ʻokoʻa antenna kaʻawale ko kēlā me kēia radar, hoʻokau ʻia me ka mīkini i ka azimuth a me ke kiʻekiʻe. Me kahi ʻōnaehana kamaʻilio ukali broadband i loaʻa kahi antenna e kau ʻia ma luna o kahi kaʻa, hoʻohana ʻia ka antenna e kōkua i ke kūkulu ʻana i kahi loulou kamaʻilio me kahi ukali ākea ākea ma ka orbit geosynchronous. Hoʻokumu ka antenna i kahi ʻāpana o kahi kikowaena kamaʻilio e lawe ʻia e ka kaʻa. Nā Antenna me ka hiki ke nānā, me ke kiʻekiʻena kikoʻī, nā satellite kamaʻilio e like me nā mokulele, nā moku a me nā kaʻa ʻāina e koi ʻia, inter alia, no ka hoʻonui ʻana i ka helu o ka ʻikepili, hoʻomaikaʻi i ka pono o ka downlink a me ka hoʻouka ʻana o ka uplink, a me / a i ʻole ke pale ʻana nā ukali e hoʻopuni ana i kahi e pili ana i kahi ukali ukali. ʻAe nā antennas e ʻae i nā papa kūkā kamaʻilio ukali kelepona e kiʻekiʻe kiʻekiʻe ai ke ʻano, e like me nā mokulele a me nā kaʻa ʻāina e loaʻa nā hōʻailona mai a / a i ʻole e hoʻouna i nā hōʻailona i nā satellite e like me nā satellite geostationary.
Hoʻokomo ka antenna rotating i kahi pae hele a me kahi kahua kaʻapuni e kākoʻo ana ma kahi o hoʻokahi aniani aniani a me kahi RF transmission / hoʻokipa unit, ke kahua paʻa a me ke kumu o ke kaʻapuni ke kaulike ʻia, kahi hoʻonohonoho rotary i hoʻonohonoho ʻia e ʻae i ka lawe ʻana o nā lekiō lekiō (RF) mau hōʻailona ma waena o ke kumu o ke kaʻapuni a me ka pae ma ka neʻe ʻana o kekahi e pili ana i kahi ʻē aʻe e pili ana i kahi axis rotation, kahi encoder i hoʻonohonoho ʻia e hāhai i ka neʻe ʻana, kahi apo slip conductive i hoʻonoho ʻia e hoʻopuni i kahi pili pono o ka hui rotary ma waena o ka pedestal a me ka rotating kumu i mālama ʻia ai kahi pilina uila ma waena ma waena o ka neʻe ʻana o ka neʻe, a me kahi kūlana annular i hoʻonohonoho ʻia e hoʻopuni i ka encoder a me nā apo o ka plurality a puni ka axis rotation a e kaohi i ka neʻe ʻana. ʻO ka hui hoʻokaʻa, ka paheʻe apo paheʻe a me ka hānau annular he concentric a me ka ami hoʻokaʻa, ka encoder, a me ka hānau annular ma kahi mokulele kaulike maʻamau.
Hoʻohana ʻia ke apo paheʻe a me ka palaki e hoʻohuli i ka kaohi uila a me ka hōʻailona kūlana i a mai nā kaapuni kiʻekiʻe ʻoiai ke kaʻapuni nei ka antenna i azimuth. ʻO ka noi ʻana o ke apo slip i ka ʻōnaehana antenna e like me ka anakahi pan-tilt. Hoʻohana pinepine ʻia kahi mīkini pan-tilt me ke apo slip hoʻohui e hāʻawi i ka hoʻonohonoho manawa maoli no ka antenna pū kekahi. Hāʻawi kekahi mau mea hana kiʻekiʻe kiʻekiʻe i ka Ethernet / pūnaewele pūnaewele, a koi ʻia ke kani slip conductive me ka lawe Ethernet.
Pono nā ʻōnaehana antena ʻokoʻa i nā apo slip like ʻole. 'Lelo maʻamau, ke apo paheʻe pinepine pinepine, ke apo slip slip (ke apo paheʻe haʻahaʻa haʻahaʻa) a ma o ke apo slip slip i hoʻokumu pinepine ʻia i nā ʻōnaehana antenna. I nā makahiki i hala iho nei, ua koi koke ka radar kai me nā antenna e neʻe nei, ʻoi aku ka nui o lākou e koi i ka pilina Ethernet. ʻAe ʻo AOOD Ethernet mau apo i 1000/100 kahua T Ethernet e pili ana mai ka hoʻopaʻa paʻa ʻana i ka paepae kaʻapuni a ʻoi aku ma mua o 60 miliona kipi i ke ola holoʻokoʻa.
