Like its predecessor DL2K, the Palstar DL5K was born out of the need for a dummy load that allows for more time to tune your amp at high power. Most dummy loads don’t have the real world power load capability needed by Ham operators who run high-power amplifiers. The Next-Generation Palstar DL5K Dummy Load for…
