Product Overview

The ARL170R250XZ is a professional log-periodic broadband antenna developed for DAB monitoring and measurement applications in the 170–250 MHz band. With a maximum gain of 9.5 dBi and 8 MHz bandwidth, it ensures accurate reception and stable performance in both fixed and mobile environments.

The antenna supports vertical and horizontal polarization, with beamwidth varying by frequency (H-plane 100° at 170 MHz, 80° at 200 MHz, 90° at 230 MHz; E-plane 60° at 170 MHz, 55° at 200 MHz, 50° at 230 MHz). Excellent matching is guaranteed with VSWR ≤ 1.5:1 and return loss ≥ -14 dB. All metallic parts are DC-grounded for lightning protection.

Two versions are available: ARL170R250XZ with folding elements for transport convenience, and ARL170F250XZ with unscrewed elements. The antenna is designed with anticorodal aluminum, brass, Teflon and PVC materials, ensuring long-term durability.

Technical Applications

  • Spectrum monitoring and interference detection
  • Measurement campaigns in urban, rural, or critical environments
  • Temporary or transportable monitoring stations requiring folding or compact antenna
  • Professional field operations by regulatory authorities, broadcasters, and institutions
