Ten-Tec Model 239, 300 Watt Dummy Load for HF & VHF NEW in Box

 
Ten-Tec Model 239 Broadband Dummy Load is a vintage dry, non-inductive 50-ohm dummy load from the late 1970s to early 1980s (introduced around 1978–1980). It was designed as a compact, affordable accessory for ham radio operators to test transmitters, tune antennas, and measure power without radiating a signal. Often sold as a kit (Ten-Tec Model 1203) that assembled into the 239, it was popular for both QRP and moderate power use.Key Details and Specifications
