ʻAntenna Kaulike Log 9dBi Typ. Gain, 0.3-2GHz Frequency Range RM-LPA032-9

ʻO kahi antenna log-periodic kahi antenna broadband kū hoʻokahi nona ka hana uila, e like me ka impedance a me ke ʻano radiation, e hana hou ʻia me ka logarithm o ke alapine (frequency). ʻO kona ʻano maʻamau he moʻo o nā mea dipole metala o nā lōʻihi like ʻole, i hoʻopili ʻia i kahi laina feeder, e hana ana i kahi ʻano geometric e hoʻomanaʻo ana i ka iwi iʻa.

Hilinaʻi kāna kumumanaʻo hana ma ka manaʻo "ʻāpana hana". Ma kahi alapine hana kikoʻī, ʻo kahi hui wale nō o nā mea me nā lōʻihi kokoke i ka hapalua o ka nalu e hoʻonāukiuki maikaʻi ʻia a kuleana no ka radiation mua. Ke loli ke alapine, neʻe kēia ʻāpana hana ma ke ʻano o ka antenna, e hiki ai i kāna hana wideband.

ʻO ka pōmaikaʻi nui o kēia antenna ʻo ia kona bandwidth ākea loa, e hōʻea pinepine ana i ka 10:1 a ʻoi aku paha, me ka hana paʻa ma waena o ka band. ʻO kona mau hemahema nui he ʻano paʻakikī a me ka loaʻa kūpono. Hoʻohana nui ʻia ia i ka hoʻokipa kīwī, ka nānā ʻana i ka spectrum full-band, ka hoʻāʻo ʻana o ka Electromagnetic Compatibility (EMC), a me nā ʻōnaehana kamaʻilio e koi ana i ka hana wideband.
