Description

Professional Vertical Double Dipole DAB Antenna 174–240 MHz

RAYTRA UDA 7.7.50.22 is a professional vertical double dipole broadcasting antenna designed for DAB/DAB+ digital radio broadcasting in the VHF Band III 174–240 MHz frequency range.

The antenna is designed for highly reliable operation in professional DAB broadcasting networks, local and regional multiplexes, and other applications where high efficiency, stable radiation characteristics, and long-term mechanical durability are required.

The two vertically arranged dipoles provide increased gain and an optimized radiation pattern compared with a single dipole antenna. The broadband design allows operation across the complete 174–240 MHz frequency range without the need for additional tuning for individual DAB channels.

All key mechanical parts of the antenna are manufactured from high-quality stainless steel, providing excellent resistance against corrosion, UV radiation, and long-term exposure to harsh environmental conditions. The antenna is suitable for installation in coastal areas and locations with high humidity.

The antenna is supplied as standard with a protective radome, which protects the radiating elements against ice, snow, rain, and other weather effects. The radome ensures reliable operation even in demanding climatic conditions, including mountain transmitter sites with a high risk of icing.

RAYTRA UDA 7.7.50.22 represents a universal solution for professional DAB broadcasting systems requiring high lifetime, minimum maintenance requirements, and stable RF performance throughout the entire service life.
