The center- and the end-insulators are fundamental parts of an doublet-antenna. By the special design and the basic material we use, the robustness against traction and climate is extremly high! The HV-insulation length is 150mms, the two ends are made in form of crane-hooks (1) and the two lateral bows (2) are prepared for a flexible suspension of the dipole-center. The length is adapted to the spreader SP-120 or the distance between the two ladderline wires, ideal for the use as a center insulator.

For avoiding crossovers or for tighten the ladderline, an insulator IS-120 to be hooked in the ladderline just near to a spreader. By guiding a thin nylon rope through the two bows (2) and by fastening its two ends in lateral position, the ladderline is tight and remains in position, with no crossoverrisk by twist.
