Swan FS-2 Vintage SWR and RF Field Strength Meter NOS in Original Box

The Swan FS-2 is a classic vintage SWR (Standing Wave Ratio) and RF Field Strength Meter from Swan Electronics (popular in the 1970s for ham radio and CB use). It combines two useful functions in one compact desktop unit: inline SWR measurement for tuning antennas and a field strength meter for checking relative RF output or antenna radiation.Key Specifications & Features

Functions: Measures SWR (typically 1:1 to 3:1 or higher scale) and RF Field Strength (relative signal strength with telescoping or external whip antenna).
Frequency Range: Primarily designed for HF bands (including 80–10 meters for ham) and 11-meter CB (27 MHz); usable across typical HF ranges with low insertion loss.
Power Handling: Suitable for low-to-medium power transceivers (users report reliable performance with 100–200W+ rigs; not a high-power directional coupler like modern wattmeters).
Connectors: SO-239 (UHF female) input and output for inline SWR use between radio and antenna.
Controls: Usually includes a function switch (SWR / FS), sensitivity adjustment for field strength, and calibration knob for SWR.
Design: Analog meter movement, battery-powered for the field strength section (common 9V or AA), compact metal/plastic case with rubber feet.
Compatibility: Works with any 50-ohm HF/CB transceiver or transmitter (Swan tube rigs like 350/500 series, modern solid-state rigs, or CB radios). Great for tuning dipoles, verticals, beams, or mobile whips.

Operation is straightforward: For SWR, connect inline and calibrate on forward power; for field strength, use the whip and move it around to peak the reading. No external power needed beyond batteries for FS mode.
