A dielectric spacer for a coaxial connector includes: a narrow ring; a wide ring attached to the narrow ring, the wide and narrow rings sharing a longitudinal axis; a plurality of posts positioned within the wide ring, each of the posts extending substantially parallel to the longitudinal axis; and a plurality of bores in the narrow ring, each of the bores extending substantially parallel with the longitudinal axis and being aligned with a corresponding post. Each of the posts is mounted on a frangible section that separates the post from its corresponding bore.
