ʻO GPS+Beidou ʻAntenna Manawa Manawa 38dBi
Hoʻolauna Huahana
ʻO GPS+Beidou Timing antenna kahi ʻano antenna i hoʻohana ʻia no ka loaʻa ʻana o nā hōʻailona ukali.Hiki iā ia ke loaʻa nā hōʻailona ukali RHCP ma ka GPS L1 a me BD B1 mau kaha alapine.
He mau hiʻohiʻona kēia antenna:
Loaʻa kiʻekiʻe: Hiki i ka antenna poʻo mushroom ikaika ke hāʻawi i ka loaʻa hōʻailona kiʻekiʻe a hoʻonui i ka mana hōʻailona nāwaliwali o ka hōʻailona i loaʻa, a laila e hoʻomaikaʻi ai i ka loaʻa ʻana o ka ʻike a me ka maikaʻi o ka hōʻailona.
Paʻa kiʻekiʻe: Hoʻolālā ʻia ka antenna me ke kūpaʻa kiʻekiʻe a hiki ke mālama i ka hana paʻa ma lalo o nā kūlana kaiapuni.ʻO ia ke ʻano hiki ke hāʻawi i ka hoʻokipa hōʻailona ukali paʻa i nā kūlana aniau a pau.
ʻO ke kikowaena pae paʻa kiʻekiʻe: ʻO ka antenna mushroom head antenna he kikowaena paʻa paʻa loa, ʻo ia hoʻi, paʻa mau ke kikowaena o ka hōʻailona i loaʻa i loko o kahi manawa.He mea koʻikoʻi kēia no ka hoʻonohonoho ʻana a me nā noi hoʻokele, no ka mea, pili pololei ka paʻa o ke kikowaena i ka pololei o ke ana.
