Porcelain 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.  There is currently no hobby numbering system established to cover radio strains.

Here is a nice selection of smaller styles that shows the variety of nice colors in which they can be found.

Here is a large 16" porcelain strain.
