Loaʻa i ka antenna kahi alapine o 1710MHz a 1880MHz, hiki ke kamaʻilio maikaʻi i ka hui 1800MHz.Hāʻawi kāna VSWR ma lalo o 2.0 i ka maikaʻi hōʻailona maikaʻi loa, hoʻemi i ka distortion hōʻailona a hoʻonui i ka wikiwiki o ka hoʻololi ʻana i ka ʻikepili.
Loaʻa i ka antenna kahi impedance komo o 50 ohms a me ka mana kiʻekiʻe o 10W, hiki ke maʻalahi i nā noi mana kiʻekiʻe.ʻO 3.0dBi o ka loaʻa e hōʻoiaʻiʻo i ka hoʻokipa hōʻailona maikaʻi loa a me ka uhi ʻana no ka hoʻopili ʻana i nā wahi paʻakikī.
ʻO ke kaupaona ʻana he 1 gram wale nō a ʻo ke ana ʻana he 20.5 mm ke kiʻekiʻe, ʻo ka antenna he māmā loa a paʻa, kūpono ia no nā ʻano mea like ʻole a me nā hoʻonohonoho.Hoʻohui ke kala keleawe i kahi hiʻohiʻona a me ka ʻoihana i kāu mea hana.
ʻO ke ʻano mea hoʻohui o kēia antenna he kūʻai pololei, kahi e hōʻoia ai i kahi pilina palekana a paʻa.Hoʻopau kēia i ka pono o nā mea hoʻohui hou aʻe a hoʻomaʻamaʻa i ke kaʻina hoʻonohonoho, mālama i kou manawa a me ka hoʻoikaika.
Ma keʻano o ka hoʻopiliʻana, ke hāʻawi nei mākou i ka pahu nui e hoʻokō i kāu mau pono kiko'ī.Mālama kēia i ka mālama maʻalahi a me ka mālama ʻana, kūpono ia no nā mea hana a me nā mea hoʻolaha.
Inā ʻoe e ʻimi nei e hoʻomaikaʻi i ka hana o kāu ʻōnaehana kamaʻilio uila a i ʻole e ʻimi ana i kahi antena hilinaʻi no kāu kelepona, ʻo ka 1800MHz Spring Coil Antenna ka hopena kūpono.Me kāna hana ʻoi aku ka maikaʻi, ka hoʻolālā paʻa a me ka maʻalahi o ka hoʻonohonoho ʻana, he koho maʻamau no nā ʻano noi.E hilinaʻi i kā mākou huahana e hāʻawi i ka pilina paʻa a me ka maikaʻi o ka hōʻailona.
