| Leader-mw | Taw qhia rau Tes-Tuav Log-Lub Sijhawm Kav hlau txais xov |
Taw qhia Cheng du tus thawj coj mcrowave Tech., (tus thawj coj-mw) tuav lub log-ntev kav hlau txais xov, qhov kawg daws teeb meem rau kev ua kom lub zog siab tshaj plaws thiab kev pab cuam hauv 800 txog 9000 MHz zaus ntau. Lub kav hlau txais xov compact tseem muaj zog no yog tsim los txhawb nqa cellular, PCS, LTE, 4G LTE thiab Wifi / WiMAX zaus bands, ua rau nws yog ib qho tseem ceeb rau txhua tus neeg uas xav tau kev sib txuas lus zoo thiab ua haujlwm siab.
Tus kav hlau txais xov log-periodic nta 6 dBi tiaj tus nce, npog L / S / C / X nrog superior precision thiab raug, xyuas kom koj nyob twj ywm tsis muaj teeb meem koj nyob qhov twg. Tshwj xeeb rau tus kav hlau txais xov no yog nws qhov hloov tau ntsug thiab kab rov tav log-periodic tsim, muab kev hloov pauv tsis tau dhau los thiab ua kom tau raws li koj cov kev xav tau tshwj xeeb thiab ib puag ncig.
Tsim los rau kev ua haujlwm ntev thiab kev ua tau zoo, tus kav hlau txais xov log-periodic nta lub zog siab, tsis tshua muaj cov yas molded radome kom ntseeg tau tias nws tuaj yeem tiv taus cov xwm txheej hnyav thiab txuas ntxiv ua haujlwm zoo. Nws txoj kev sib hloov rab yaj phom ntxiv ntxiv rau kev yooj yim thiab yooj yim ntawm kev siv, tso cai rau koj kom yooj yim kho tus kav hlau txais xov kom ua kom zoo dua cov teeb liab txais.

Log-periodic DipoleAntenna siv
(1) Feem ntau siv nyob rau hauv ultra-luv nthwv dej band, kuj tseem siv tau raws li luv yoj kav hlau txais xov thiab nruab nrab nthwv dej, luv yoj tshaj tawm xov tooj cua kis tau tus mob. Log-periodic kav hlau txais xov kuj tseem siv tau los ua feeders rau microwave reflector antennas. Nws tuaj yeem siv rau hauv xov tooj cua amateur thiab pej xeem band xov tooj cua ua haujlwm, nrog rau kev tshawb fawb thiab kev saib xyuas.
(2) Log-periodic Dipole Kav hlau txais xov, lawv muaj peev xwm tswj tau cov qauv hluav taws xob zoo ib yam dhau ntawm ntau qhov ntau zaus, ua rau lawv muaj txiaj ntsig zoo hauv cov ntawv thov uas cov kav hlau txais xov yuav tsum tuaj yeem ua haujlwm hla ntau zaus tsis muaj kev hloov kho loj lossis hloov kho.
