ADB2-ADN2 is a wideband UHF omnidirectional antenna designed to improve reception for wireless audio systems. It covers 430–1160 MHz with about 3.2 dBi gain and vertical polarization. The 50 Ω impedance, epoxy fiberglass body, and black matte weather‑resistant coating ensure durability in field installations. Variants mount on 5/8" or 3/8" threads via a metal base; connectors are BNC-F (ADB2) or N-F (ADN2). Dimensions are 290 × 111 × 40 mm (N) or 290 × 111 × 28 mm (BNC).
