A kav hlau txais xov dipole yog lub xov tooj cua kav hlau txais xov uas tuaj yeem ua los ntawm txhuas, tooj liab, thiab tooj dag raj nrog qhov nruab nrab-ua lub tshuab ua kom lub zog. Nws muaj ob txoj hlua hlau ntawm tus pas nrig, taw qhia mus tib seem thiab collinear nrog txhua lwm yam (nyob hauv kab nrog ib leeg), muaj qhov chaw me me ntawm lawv.

cov kav hlau txais xov dipole yog daim ntawv tseem ceeb tshwj xeeb ntawm RF kav hlau txais xov uas yog dav siv rau xov tooj cua sib kis thiab tau txais cov ntawv thov. Lub dipole feem ntau siv nws tus kheej xws li tus kav hlau txais xov RF, tab sis nws kuj tsim cov yam khoom tseem ceeb hauv ntau lwm hom xov RF. Xws li nws yog qhov tsim nyog tau yog qhov tseem ceeb ntawm daim ntawv xov tooj cua RF.

A kav hlau txais xov ib nrab yoj dipole txhais tau hais tias qhov ntev ntawm lub kav hlau txais xov dipole yog sib npaug li ib nrab-ntu ntev ntawm qhov zaus ua haujlwm.

Vim li cas peb thiaj qhia lub kav hlau txais xov dipole?saib


1) .Qhov ib nrab nthwv dej dipole yog qhov tseeb thiab yooj yim rau kev hloov kho zaus, muaj cov nplai ntawm ib sab ntawm tus kav hlau txais xov los ntawm qhov koj tuaj yeem kho qhov zaus los ntawm 88 ~ 108 los ntawm 1mhz stepping.dispole1


2) .Qhov dipole yog lub kav hlau txais xov uas yooj yim rau kev tsim kho thiab siv, thiab ntau yam ntawm cov kev suav tau yooj yim heev.IMG_5587



3.) Qhov qauv hluav taws xob thiab qhov nce siab ntawm dipole:

Cov qauv hluav taws xob tawg ntawm lub kav hlau txais xov dipole ib nrab, nplai yog kab tawm.

    Ntau npaum li cas Fmuser transmitter 7 watts, 15 watts thiab 25 watts?
    muaj pes tsawg hnub kuv yuav rov qab tau kuv cov ntawv xaj?
    koj puas tau tiv toj zoo li tus xa xov?
