LPCB-425606-01: Quad-Band Log Periodic Antenna (500-6000 MHz)

LPCB-425606-01 | Quad-Band Log Periodic Antenna (425–6000 MHz)

The LPCB-425606-01 is a compact, PCB-based broadband log-periodic dipole array (LPDA) engineered to deliver wideband RF coverage, stable directional performance, and cost-effective deployment across a broad frequency range. Optimized to cover the primary communication bands used in unmanned aerial systems (UAS) and drones, the antenna enables reliable reception and transmission across control links, telemetry, and data channels commonly operating from sub-GHz through C-band frequencies.

Designed for demanding applications including drone communications, spectrum monitoring, surveillance, RF testing, and directional communications, the LPCB-425606-01 provides predictable gain, consistent radiation patterns, and repeatable electrical performance. Operating from 425 MHz to 6.0 GHz, the antenna delivers +6.5 dBi nominal gain, controlled beamwidth, and excellent impedance match across the band.

Its lightweight PCB construction supports low-profile integration into portable or field-deployed systems, while maintaining rugged mechanical integrity for reliable operation in dynamic and outdoor environments.
