Water dielectric loads employ a novel method of RF absorption and heat dissipation.
These are designed using controlled elements of water within a dielectric sleeve or cone to both absorb the heat generated and offer exceptional RF performance. Detailed below are some typical existing designs. These are generally reduced bandwidth designs.
