An elongated antenna, especially an omnidirectional antenna, has a vertical, elongated rod-like structure with two metal profile elements (10, 20) provided with dipole elements (2) as integral parts thereof. The rod-like structure (1) is surrounded by a tube (3). The antenna elements (2) are coupled in parallel to a single transmission coaxial cable (8). The antenna has a high gain and low losses.
