Salt Water Dummy Load
A dummy load is a piece of equipment which allows transmitter testing and adjustment with minimal radiation of RF energy.
Most dummy loads are constructed using non-inductive resistors and utilize various heat sinking methods, ranging from passive air cooling (e.g. Elecraft DL-1, MFJ-261) to submersion in non-conductive oil baths (e.g. Heathkit Cantenna, MFJ-250), to dissipate the transmitter power.
