ARL03810X Logperiodic Directional Logarithmic Antenna DAB Stainless Steel Aluminum 170 230 MHz - DAB ANTENNAS Professional antennas for Digital Audio Broadcasting transmission systems

Overview

The ARL03810XZ Log-Periodic Antenna is a professional directional antenna designed for Digital Audio Broadcasting (DAB) Band III, 170–240 MHz. Thanks to its broad 70 MHz bandwidth and stable performance, it provides reliable transmission across the entire DAB spectrum.

Engineered and manufactured in Italy, it is built with stainless steel, aluminium, Teflon and brass components, ensuring durability and compliance with RoHS standards.

Technical Highlights

The ARL03810XZ log-periodic antenna provides broadband directional coverage across the entire DAB Band III (170–240 MHz). With its 70 MHz bandwidth, the antenna does not require retuning and guarantees stable performance over all DAB blocks. Offering a maximum gain of 9.5 dBi and optimized radiation patterns, it is suitable for both broadcast transmission and professional monitoring applications.

Its log-periodic design ensures excellent front-to-back ratio and suppression of unwanted signals, particularly valuable in high-interference environments. The antenna supports vertical or horizontal polarization and can be integrated into collinear or multi-antenna systems to expand coverage and increase gain when required.

Manufactured in Italy using stainless steel, anticorodal aluminium, brass, and Teflon, the ARL03810XZ offers long-term durability and RoHS compliance. Its rugged structure, together with optional mounting accessories, makes it a reliable choice for permanent outdoor installations, even in challenging environmental conditions.
