CHA CFM-34 Product DNA: Complete System Overview

The CHA CFM-34 puts a wire antenna more than 34 feet above the site while collapsing to 23 1/2 inches. At 2 lb 9 oz, it gives portable, HOA, and field operators practical height without committing the property or vehicle to a permanent tower.

Start with the job: The CHA CFM-34 puts a wire antenna more than 34 feet above the site while collapsing to 23 1/2 inches. At 2 lb 9 oz, it gives portable, HOA, and field operators practical height without committing the property or vehicle to a permanent tower.

Why this part earns its place

  • Choose it when the antenna benefits from substantially more height and the site can safely accommodate the larger fall radius.
  • The published mast load is 1 lb; include every suspended feedpoint, wire, carabiner, and vertical pull in that decision.
  • Use a documented 3/8-24 base mount and stabilize the complete footprint before raising the antenna.
  • Compare the 34-foot footprint with CFM-16 before assuming taller is always easier or better.

What a complete deployment includes

  • Seat the mast base fully against the selected mount.
  • Attach and strain-relieve the antenna before raising the mast.
  • Extend sections from the top down without forcing or over-pulling them.
  • Route the wire so the mast is a support, not an unintended parallel conductor.

Compatibility that matters

  • Use the guide table for approved Chameleon wire-antenna attachment methods.
  • The base can engage a CHA SPIKE MOUNT or UCM, but the site and load still control whether that mount is appropriate.
  • Carbon fiber is conductive enough to couple to nearby wire; preserve the separation and geometry described by the antenna guide.
  • Do not infer compatibility from a tip ring, carabiner, or 3/8-24 thread alone.

Field safety and recovery

  • Keep the full mast and antenna fall zone away from people, power lines, structures, and traffic.
  • Reduce height or lower the system when wind or wire tension makes the mast unstable.
  • Stay within the 1 lb published load.
  • Do not erect or lower the mast without controlling every attached wire and feed line.
  • Lower sections from the bottom upward.
  • Clean and dry every section before storage.
Use the current CHA CFM-34 instructions.
