Choose from the complete load: CHA HD GUY CLAMP is the two-piece mast ring used to connect the UGS three-line system to larger CFM masts. It creates a deliberate guy point without drilling or improvising attachments on the carbon-fiber tube.

Use these selection checks

  • Choose it for the CFM-34 or CFM-34HD path described by the UGS and mast guides.
  • Confirm the selected mast section is the documented 24-26 mm diameter at the correct guying height.
  • Use all supplied stainless hardware and three carabiners.
  • Do not treat the clamp as a lifting point, antenna bracket, or reason to exceed the mast rating.

Confirm the support chain

  • The clamp is documented with CFM-34, CFM-34HD, and the UGS guy-line system.
  • Its physical diameter range does not approve every mast material or load.
  • The antenna-specific height and guying restrictions still control.
  • Do not substitute generic clamps or fasteners.

Reject the plan when

  • Never install it on a cracked, deformed, or wrong-diameter section.
  • Do not overtighten into carbon fiber.
  • Keep hands clear while a loaded mast moves.
  • Lower the mast immediately if the clamp rotates, slips, or separates.

Price and physical fit come after the site, load, and complete configuration. If any published limit is missing, do not silently invent one; reduce the load or ask Chameleon technical support to review the exact installation.
