Overview
The ARYCKM-D-25X is a professional 2-element Yagi antenna for DAB VHF Band III (174–240 MHz). It delivers a narrow-band response (10 MHz) with a maximum gain of 7.2 dBi, VSWR ≤ 1.5:1 and return loss ≥ –14 dB.
Linear polarization (V/H), robust stainless-steel support, and aluminum or stainless-steel radiating elements ensure high mechanical reliability. All metal parts are DC-grounded for lightning protection. An optional PVC radome is available for harsh environments. Connector options: N-male (500 W) or 7/16″ (1000 W).
Technical Highlights
The two-element Yagi antenna is designed for Digital Audio Broadcasting (DAB) in the 174–240 MHz range. Its directional radiation pattern provides focused coverage with moderate gain, making it ideal for professional installations that require targeted transmission without excessive complexity.
Each antenna is factory-tuned to the requested DAB block and built using high-grade stainless steel or aluminium for durability and weather resistance.
