Glass Radio Strain Insulators |
Radio strain insulators are used to insulate either end of a wire antenna from the tower or other mounting hardware. The smaller styles were frequently used by HAM radio hobbyists for back yard antenna installations. There is a tremendous variety of these available and there are collectors that specialize in these styles.
By far, the bulk of radio strains are found in clear glass. Here is a variety of smaller clear glass styles. |
