Antenna Tools

Test equipment, measurement tools, and software for antenna work: analyzers, power meters, modeling, and SDR interfaces.

  • ADF Systems — Automatic direction finding systems and loop antennas
  • Antenna Analyzer — Impedance measurement, SWR sweeps, resonance finding
  • Antenna Modeling — NEC2, EZNEC, 4NEC2 modeling tools and files
  • Dummy Loads — 50Ω non-radiating loads for transmitter testing and calibration
  • Field Strength Meter — Near-field RF measurement, antenna comparison
  • Noise Bridge — Impedance and resonance measurement using a noise source
  • RF Power Meter — Directional wattmeter, Bird slug meters, QRP power heads
  • RF Power Meters (Legacy) — Older power meter designs and cross-needle instruments
  • SDR Interfaces — Upconverters, preselector, bias-T, direct sampling modifications
  • SWR Meter — Standing wave ratio bridges, reflectometer circuits
