This JNC RADIO JLoad-200 is a high-power, passive air-cooled RF dummy load designed for the serious amateur radio operator or commercial communication service technician.
It serves as a 50-ohm electrical substitute for an antenna, allowing you to test a transceiver's power output and performance without actually radiating a signal over the air.
Are they build solid? Oh, YES, they're built to last! "JNC Radio Quality - Made by Hams, for Hams".
