The Anritsu MA2700A is a handheld directional finding antenna system that locates RF interference sources by capturing signal direction and position data in real time. Designed to integrate with Anritsu handheld spectrum analyzers running Interference Analysis (Option 25) or Interference Finder (Option 24) software, the MA2700A combines GPS positioning, electronic compass bearing, and a user-selectable broadband preamplifier in a single ergonomic unit. A simple trigger press records bearing and location coordinates, which map directly onto the host instrument display for efficient interference hunting across the 9 kHz to 6 GHz band.

– Compatibility & Integration
The MA2700A requires an Anritsu handheld spectrum analyzer with Interference Analysis (Option 25) or Interference Finder (Option 24) software. Directional antenna boom connector must be positioned ≥ 16 cm from the rear-most element for vertical polarization, with rear element length not exceeding 7.5 cm. Torque enhancer removal is required when used with Anritsu low-frequency directional antennas.
