Machined from solid aluminum, the FGKLMUP15 replaces the older plastic KLM element clamps used in KLM’s original 40m designs. Using ultra-precise computer numerically controlled (CNC) manufacturing techniques, these clampsprovide a secure grip under even the worst conditions. All-aluminum clamp construction eliminates susceptibility to ultraviolet radiation, wind and cold.
Direct replacement for the front and rear driven elements on the KLM 40m series antennas, these require very little additional work to replace weakened plastic pieces. They clamp easily to the boom and eliminate stresses resulting from the split-element concept by joining each element half with a 1” diameter solid fiberglass rod for a single super-strong, ultra-resilient element.
Other antennas can also benefit from this upgrade. Many popular HF antennas, made by KLM and other manufacturers use 1 1/4” diameter tubing with .058” wall thickness for driven elements. A 1-1/8" sleeve (not provided) may be required for other manufactures elements if not double walled. On a 3” boom, this element clamp is ideal. Do you have an HF antenna design that you would like to try? These clamps are perfect for home brew projects. Use them with 1 1/4” x .058” tubing to create driven elements for your own Yagi or log periodic design.
