The ARDU.02 is an omnidirectional collinear wideband antenna system for UHF TETRA / TETRAPOL networks in the 380-470 MHz range, engineered to deliver a perfectly circular horizontal radiation pattern for reliable 360-degree coverage.

Its key advantage is the easy mechanical +/- adjustment of the vertical radiation pattern, allowing optimization of site coverage without changing the antenna type. This makes ARDU.02 ideal for engineered installations where coverage shaping and repeatability are essential.

Built in stainless steel with no plastic parts, ARDU.02 is IP65 waterproof, electrically grounded and designed for long-term outdoor operation on professional UHF sites.
