The SCALA 4DR-BU Panel Series is the next generation of the longproven 4DR design, offering full 470-608 MHz broadband capability with Horizontal, Elliptical, or Circular polarization options. Engineered for ATSC 1.0 and 3.0 applications, the 4DR-BU provides stable patterns, low VSWR, and consistent performance across the entire band.
Panels can be combined to create standard or custom radiation patterns, and each array includes matched power dividers, coax feeders, and mounting hardware. Constructed from corrosion-resistant aluminum and stainless steel and protected by a rugged fiberglass radome, the 4DRBU is built for long-term reliability in severe weather environments.
The 4DR-BU extends SCALA's proven reliability with full broadband capability and the optional addition of a vertical component to enhance indoor penetration and mobile reception for ATSC 3.0.
