Product Overview
The ARM2DAB is a professional mobile omnidirectional antenna with a magnetic base, specifically developed for DAB monitoring and measurement applications in the VHF band 174–240 MHz. It provides 2.2 dBi typical gain with an 80 MHz operating bandwidth, ensuring stable omnidirectional coverage during on-the-move measurements.
The antenna operates with vertical polarization, offering VSWR ≤ 2.5:1 and return loss ≥ -10 dB. A robust UPVC radome protects against weather and shocks, while all metallic parts are DC-grounded for effective lightning protection. Quick and secure installation is achieved through three high-strength magnets positioned at 120° under the ground plate, ensuring stability up to 120 km/h.
