Direction Finder

Precision-engineered antennas for wideband testing, communication, and defense applications.

DIRECTION FINDER

Direction Finder (DF) antennas are specialized multi-element systems engineered to determine the direction (bearing) of incoming RF signals with high accuracy. They deliver phase-coherent, broadband performance required in applications such as spectrum monitoring, interference hunting, COMINT, TSCM, and search-and-rescue operations. Designed for fixed sites, mobile deployments, and tactical field units, DF antennas maintain stable phase relationships and low bearing error across wide frequency bands.
