The Kenwood TH-21E is a compact single-band 2m handheld from Kenwood's first-generation "Pocket" series, manufactured from 1984 onward. With 1 W (high) or 150 mW (low) output power and a double-conversion superheterodyne receiver, it targeted amateur operators wanting an especially small and light rig. It has no memory channels and is tuned directly via a frequency selector. As the forerunner of the TH-2x series, it is now a sought-after collector's item, partly due to its appearance in the film "Die Hard".
