FMUSER DP100 Dipole FM Antenna Yokhala Ndi Chingwe cha 8-Meter RG58

Antenna ya dipole ndi mlongoti wa wailesi yomwe imatha kupangidwa ndi aluminiyamu, mkuwa, ndi chubu cha bronze chokhala ndi chinthu choyendetsedwa ndipakati. Amakhala ndi zitsulo ziwiri zazitsulo za ndodo, zogwirizana ndi zofanana ndi collinear wina ndi mzake (mu mzere wina ndi mzake), ndi malo ochepa pakati pawo. Mlongoti wa dipole ndi mtundu wofunikira kwambiri wa mlongoti wa RF womwe umagwiritsidwa ntchito kwambiri potumiza ndi kulandira mapulogalamu. Dipole imagwiritsidwa ntchito yokha ngati mlongoti wa RF, komanso imapanganso chinthu chofunikira pamitundu ina yambiri ya RF antenna. Chifukwa chake mwina ndiye mtundu wofunikira kwambiri wa mlongoti wa RF. Mlongoti wa dipole wa theka-wave amatanthauza kutalika kwa mlongoti wa dipole uyu ndi wofanana ndi theka-wavelength pamafupipafupi a ntchito.

ubwino

Theka-wave dipole ndi yomveka bwino komanso yosavuta kusintha pafupipafupi, pali masikelo pamphepete mwa mlongoti momwe mungasinthire ma frequency kuchokera 88 ~ 108 ndi 1mhz popondapo.

Dipole ndi mlongoti wosavuta kupanga ndi kugwiritsa ntchito, ndipo mawerengedwe ambiri ndi olunjika.

chisamaliro

Mukayika mlongoti, mapeto a "Anode" ayenera kuyang'ana mmwamba, "electrode negative" ayenera kuyang'ana pansi.
