Na-ewebata onye ndu Cheng du mcrowave Tech.,(onye isi-mw) antenna log-periodic nke ejiri aka, ihe ngwọta kacha mma maka ịbawanye ike mgbaama na mkpuchi n'ogo ugboro 800 ruo 9000 MHz. Emebere antenna kọmpat ma dị ike iji kwado ekwentị mkpanaaka, PCS, LTE, 4G LTE na Wifi/WiMAX ugboro ugboro, na-eme ka ọ bụrụ ngwá ọrụ dị mkpa maka onye ọ bụla chọrọ nkwukọrịta ikuku nwere ntụkwasị obi na arụmọrụ dị elu.
Antenna log-periodic nke ejiri aka nwere atụmatụ 6 dBi flat, na-ekpuchi L/S/C/X na nkenke na izi ezi dị elu, na-eme ka ị nọrọ na njikọ n'agbanyeghị ebe ịnọ. Pụrụ iche na antenna a bụ nhazi ogologo oge na kwụ ọtọ, na-enye mgbanwe na mgbanwe na-enwetụbeghị ụdị ya iji gboo mkpa na gburugburu gị.
Ezubere maka ịdịte aka na ịrụ ọrụ, antenna log-periodic antenna nwere ike dị elu, rọba dị ala kpụrụ radome na-agba mbọ hụ na ọ nwere ike idi ọnọdụ siri ike wee gaa n'ihu na-arụ ọrụ pụtara ìhè. Njide egbe ya na-atụgharị na-agbakwunye na ịdị mma na ịdị mfe iji, na-enye gị ohere ịhazigharị antenna ngwa ngwa iji bulie nnabata mgbaama.
