Alakaʻi-mw | Hoʻolaunaʻi I Ultra Boad Beatndirediational Antenna |
Ka hōʻikeʻana i ke alakaʻi Microwave Tech. Ua hoʻolālāʻia kēia antenna ikaika e hana ma luna o kahi ākea ākea mai ka 20mhz i 3000mhz
ʻOi aku ka nui o ka loaʻaʻana o kēia Antenna ma mua o 0DB, aʻo ka pae kiʻekiʻe kiʻekiʻe loaʻo ± 1.5db Ua hoʻonui houʻia kāna hana e kahi kiʻi kiʻi kiʻi o ± 1.0DB
Loaʻa i nāʻano he Ant0104 i nāʻano polarizad Eia kekahi,ʻo ka volwna a Antenna
Hāʻawiʻia kāna hoʻolālā hoʻonohonoho a me ka hana i kūpono no ka mea i loko a me nā mea waho, a hiki i kona hana ampnidirectional e pili ana i ka piliʻana i kekahi wahi.
Inā makemakeʻoe e hoʻonui i ka ikaika hōʻailona o kāu pūnaewele pūnaewele, hoʻonui i ka hana o kāu'ōnaehana ākea, a makemake wale paha e hōʻoia i keʻano kūpono o keʻano.
