ANT0025PO Antenna ogalaau o lo'o uulima lima
| Taitai-mw | Fa'atomuaga ile Antenna Fa'ato'aga-Tu'ulima |
Fa'ailoaina Cheng du leader mcrowave Tech.,(leader-mw) antenna log-periodic u'ulima, o le fofo sili lea mo le fa'ateleina o le malosi o fa'ailo ma le fa'asalalau i le 800 i le 9000 MHz laina fa'alava. O lenei antenne laititi ae mamana ua mamanuina e lagolago ai le telefoni feaveai, PCS, LTE, 4G LTE ma le Wifi/WiMAX fa'avevesi, ua avea ai ma meafaigaluega taua mo so'o se tasi e mana'omia feso'ota'iga uaealesi faatuatuaina ma maualuga.
O le antenna ogalaau fa'apipi'i lima e fa'aalia ai le 6 dBi flat gain, e ufiufi ai le L/S/C/X i le sa'o lelei ma le sa'o, fa'amautinoa e te fa'afeso'ota'i e tusa lava po'o fea e te i ai. E tulaga ese i lenei antenna o lona fesuia'i tu'usa'o ma fa'alava ogalaau-taimi mamanu, e maua ai le fetuutuuna'i e le'i tupu muamua ma fetuutuunai e fetaui ma ou manaoga faapitoa ma le siosiomaga.
Fuafuaina mo le tumau ma le faʻatinoga, o le antenna log-periodic antenna o loʻo faʻaalia ai se radome faʻapipiʻi palasitika maualuga-maualalo e faʻamautinoa e mafai ona tatalia tulaga faigata ma faʻaauau pea ona tuʻuina atu faʻatinoga mataʻina. O le fa'aogaina o le pistol grip e fa'aopoopo atili i le fa'aogagofie ma le faigofie o le fa'aoga, e mafai ai ona e fa'afaigofie ona fetu'una'i le antenna e fa'amalieina ai le mauaina o fa'ailoga.

Log-periodicDipoleAntenna fa'aoga
(1) E masani ona faʻaaogaina i le ultra-puupuu puʻupuʻu galu, e mafai foʻi ona faʻaaogaina e fai ma antenna fesoʻotaʻiga pupuu ma galu feololo, antenna faʻasalalau faʻasalalauga puʻupuʻu. E mafai fo'i ona fa'aoga antenna o lo'o fa'asolo e fai ma fafaga mo fa'aantenna fa'aaono microwave. E mafai ona fa'aoga mo le leitio fa'ata'ita'i ma le sitiseni fa'aili fa'agaioiga, fa'apea fo'i su'esu'ega fa'asaienisi ma le mata'ituina.
(2) Log-periodic Dipole Antenna, latou te mafaia ona faʻamautu faʻasologa faʻasalalau faʻasalalau i luga o le tele o laina laina, faʻaaogaina i talosaga e manaʻomia e antennas e mafai ona galue i luga o le tele o laina faʻasalalau e aunoa ma ni suiga tetele poʻo ni suiga.
