  • Field Strength Meter – a simple indicating device useful for checking relative field strength from a directional antenna and identifying RF hotspots.  The choke can be replaced by a tuned circuit
  • Antenna Analyser – a sophisticated device which comprises an oscillator with a wide tuning range and a bridge.  Allows SWR and complex impedance (as series resistance and reactance) to be read when setting up antennas and transmission lines, as well as velocity factor and cable loss
