Overview
The Omnidirectional Dipole DAB Antenna ARDCKM-D-13X is a professional broadcast antenna for the 174–240 MHz VHF Band III. Engineered and manufactured in Italy, it provides uniform omnidirectional coverage, stable performance over a 20 MHz bandwidth, and a maximum gain of 3.7 dBi.
It is available in stainless steel or anticorodal aluminium versions, with an optional PVC radome recommended for mountain (ice) or coastal (salt corrosion) installations. All metallic parts are DC-grounded for lightning protection.
Technical Highlights
The ARDCKM-D-13X is designed for professional DAB broadcast coverage in the 174–240 MHz range. Thanks to its omnidirectional pattern, it ensures uniform signal distribution across 360° in the horizontal plane. Each antenna is factory-tuned to the requested DAB block, delivering excellent stability, low VSWR, and long-term reliability.
Its rugged construction in stainless steel or anticorodal aluminium makes it suitable for permanent installations in any climate.
