SwissRadioDay 2025 to explore future strategies for resilient radio
Tech Focus: Dielectric’s new DCR-E FM antenna fills the gap between its lowest power DCR-T and higher power ring antennas. It brings many of the same design and performance characteristics to radio stations requiring input power ratings up to 4 kW per bay. Dielectric says the ring antenna design offers exceptional pattern circularity and radiates true circular polarization with a strong axial ratio, increasing performance for optimal coverage and market penetration.
The DCR-E element is based on the DCR-T, so Dielectric can produce DCR-E antennas under tight deadlines. The most notable design difference is a pressurized balun that increases the DCR-E’s power rating four-fold compared to the DCR-T.
As with all DCR antennas, the DCR-E is lightweight with a robust structure and low wind load, increasing long-term reliability, simplifying maintenance and reducing stress on tower and building structures. The design architecture is scalable to 12 bays, each weighing only 18 pounds (8.2 kg), making traditional mounting and installation quick and straightforward. The DCR-E offers stackable bay designs in center or end-fed configurations, flexible wavelength spacings and null fill and beam tilt options.
