CRFS DFH500 Direction Finding Antenna

By elevating direction-finding heads and RF sensors above surface clutter, BlueSky Mast systems give EW operators the vertical reach to intercept, analyze and geolocate tactical communications signals (COMINT/SIGINT) across contested environments.

BlueSky Mast + DFH500 Direction Finding Antenna

Designed to support expeditionary electromagnetic spectrum operations (EMSO), SIGINT and border security missions, BlueSky Mast systems deploy RF sensors and wideband DF antenna arrays above ground-level clutter, foliage and terrain. By securing a clear 360-degree line of sight, BlueSky's tool-less, rapid-deployment masts expand detection horizons, minimize signal attenuation and deliver the persistent, reliable tracking required in high-threat tactical environments.

Benefits
Rapidly elevating sensor heads above terrain variations, buildings, and tree lines ensures unimpeded RF line-of-sight coverage for 360-degree spectrum monitoring.
Stable, high-altitude positioning extends the horizon for VHF and low-UHF signals, increasing the reaction window for emitter geolocation and tactical intercept.
Engineered for severe conditions, BlueSky Masts match the rapid 20-minute deployment tempo of mobile Rapid Deployment Kits (RDKs), allowing 1–2 operators to erect and strike sensor masts swiftly.
Rigid vertical support prevents mast vibration and mechanical movement, ensuring pristine angle-of-arrival (AoA) data feeds and precise emitter bearing accuracy.
Lightweight, modular deployment mechanisms require minimal manpower to operate, keeping tactical teams agile and responsive during rapid position shifts.
