FMUSER DP100 Dipole FM Antenna nwere eriri 8-mita RG58

Anten dipole bụ antenna redio nke enwere ike iji aluminom, ọla kọpa na tube ọla mee ihe nwere mmewere na-enye nri etiti. Ọ mejupụtara abụọ metal conductors nke mkpara, gbakwasara yiri na collinear na onye ọ bụla ọzọ (na akara na onye ọ bụla ọzọ), na a obere ohere n'etiti ha. antenna dipole bụ ụdị dị mkpa nke antenna RF nke a na-ejikarị eme ihe maka mgbasa ozi redio na ịnweta ngwa. A na-ejikarị dipole eme ihe n'onwe ya dị ka eriri RF, mana ọ na-etolitekwa ihe dị mkpa n'ọtụtụ ụdị antenna RF ndị ọzọ. N'ihi ya, ọ nwere ike bụrụ ụdị antenna RF kacha mkpa. Anten dipole ọkara ebili mmiri pụtara ogologo nke antenna dipole a hà nhata ọkara wavelength na ugboro ole a na-arụ ọrụ.
