Swage-Swage Insulators are Designed for ultimate electrical and strength characteristics SeaRig insulators deliver radio performance and improve antenna tuning. As an integral component to the rig they are easily adapted for rod or wire use with the modular components found in the range. An anodised alloy body with insulating acetal ends captivate the stainless steel studs making up this maintenance free unit. Wet or dry electrical capacitance is low at even the highest transmitting power.
