# RFlect **Antenna measurement visualization and analysis.**

RFlect turns antenna-chamber and VNA output into 2D/3D radiation-pattern plots, TRP and gain metrics, polarization analysis, UWB characterization, and DOCX reports.

It is analysis software, not a certified test laboratory. TRP uses the CTIA / IEEE-149 discrete solid-angle form; that is a calculation convention, not lab accreditation or product certification.

Scan type selection

What you get

Quickstart → Install, import a measurement, render your first plot in under five minutes. User Guide → Active TRP, passive gain, S11, group delay, UWB, polarization, maritime. All the math. MCP Server → 61 tools that let Claude Code & Cline drive RFlect programmatically. Standard Procedures → One call: process_folder(...). Passive / active / cal-drift / UWB / auto. Measurement Types → Every scan type and analysis, its input format, and the MCP tool that drives it. Hardware & Formats → WTL chambers, Touchstone .s2p, S2VNA CSV, CST. The full input/output matrix.

Built for the way RF labs actually work

  • No API key, no subscription, no LLM dependency: RFlect is a deterministic RF analysis + rendering toolkit. Every metric is computed, not generated.
  • MCP server: 61 tools that let Claude Code, Cline, and other MCP clients drive RFlect programmatically. The agent is the LLM; RFlect provides the data and the rendering.
  • GUI: desktop app (Tk-based, dark theme) for interactive review. Launch with python run_rflect.py or rflect after pip install -e ..
  • Agent-authored reports: DOCX with embedded plots and gain tables; prose is data-driven by default, or supplied by the driving agent via generate_report's narrative parameter
  • Cal-drift tracker: record TRP-Cal runs over time, compare across epochs, flag setup-group mismatches

Inputs at a glance

The public repository does not include customer chamber files. Screenshots below are representative GUI outputs. Tests use synthetic fixtures plus optional local files via RFLECT_TEST_DATA_DIR. See the README.
