OMNIDIRECTIONAL TETRA ANTENNA
MOD. ARDU.01
BROADBAND DIPOLE ANTENNA 380-470 MHz

The ARDU.01 is a wideband omnidirectional dipole antenna developed for the 380-470 MHz UHF range, delivering a perfectly circular horizontal pattern for consistent 360-degree coverage around the site.

Built for professional infrastructures, it is made of stainless steel with no plastic parts and provides high electrical and mechanical performances. This model is particularly suitable for high gain collinear systems and engineered installations where repeatable omnidirectional behavior is required.

The antenna is completely waterproof (IP65) and D.C. grounded, supporting long-term reliability in outdoor UHF sites.

Standard supply includes N female connector rated for 500 W and a supporting structure (fiberglass support is provided in standard supply). Linear polarization is available as V/H with +/-45 deg option, enabling integration in multi-site and multi-operator UHF networks.

Typical uses include TETRA / TETRAPOL omnidirectional coverage around sites, public safety and utility radio infrastructures, and collinear arrays where robust construction, sealing and stable radiation behavior are essential.

Antenna designed and manufactured in Italy.
