J pole antenna A Slim Jim is a type of a vertically polarized free space end-fed omnidirectional dipole antenna. Owing to its increased radiation length and hence lower angle of radiation in a horizontal plane, a Slim Jim antenna shows approximately 50% more radiated power than a quarter-wave ground-plane antenna |
