Mounting the CHA TACYAGI-70: Direct 1/4-20 and Chameleon 3/8-24 Support Paths

Choose the direct 1/4-20 tripod path or the CHA SS Adapter path for documented CHA SPIKE MOUNT, CHA UCM, and CHA CARBON FIBER TRIPOD configurations.

TACYAGI-70 Handbook CHA TACYAGI-70 Reviewed 2026-08-04
Quick Answer: The removable CHA TACYAGI-70 handle has a 1/4-20 female threaded socket. Mount it directly to a structurally suitable tripod head with a 1/4-20 male stud, or install the CHA SS Adapter when entering a documented Chameleon 3/8-24 support stack.

Quick Decision

  • Handle directly on a 1/4-20 male tripod head: no CHA SS Adapter.
  • Any documented Chameleon 3/8-24 extension or mast between the handle and base: CHA SS Adapter required at the handle.
  • CHA CFM-34 HD: use only above the CHA SPIKE MOUNT or CHA UCM; never place it on the CHA CARBON FIBER TRIPOD.

Interface Map

Direct 1/4-20 tripod path

TACYAGI handle, 1/4-20 female → tripod head, 1/4-20 male. This is the only listed arrangement that does not require the CHA SS Adapter.

Chameleon 3/8-24 support path

TACYAGI handle, 1/4-20 female → CHA SS Adapter, 1/4-20 male to 3/8-24 male → documented extension or mast → approved base support. The adapter converts the handle interface; it does not by itself establish the completed structure's capacity.

Documented Configuration Matrix

Base support Support above the base Adapter rule Boundary
CHA SPIKE MOUNT CHA MIL EXT 2.0, CHA SINGLE-EXT, CHA SINGLE-EXT SHORT, or CHA CFM-34 HD CHA SS Adapter required at handle Suitable soil and complete stability check required.
CHA UCM CHA MIL EXT 2.0, CHA SINGLE-EXT, CHA SINGLE-EXT SHORT, or CHA CFM-34 HD CHA SS Adapter required at handle Clamp only to a rigid, load-capable surface.
CHA CARBON FIBER TRIPOD Direct handle mounting, or CHA MIL EXT 2.0, CHA SINGLE-EXT, or CHA SINGLE-EXT SHORT with required interfaces No adapter for direct handle mounting; CHA SS Adapter required with an intervening 3/8-24 support CHA CFM-34 HD is prohibited on this tripod.

Direct Tripod Procedure

  1. Inspect the handle socket and tripod stud for damage, contamination, and correct 1/4-20 thread.
  2. Seat the removable handle securely on the boom.
  3. Thread the handle onto the tripod head by hand without cross-threading or forcing the joint.
  4. Spread and secure the tripod legs, balance the antenna, route the feed line with strain relief, and verify the intended polarization and aim.
  5. Recheck stability before transmitting and whenever the antenna is repositioned.

Adapted Support Procedure

  1. Thread the 1/4-20 side of the CHA SS Adapter into the handle by hand.
  2. Connect the exposed 3/8-24 side to the selected documented extension or mast path.
  3. Install the support above a CHA SPIKE MOUNT, CHA UCM, or an allowed CHA CARBON FIBER TRIPOD interface.
  4. Verify every joint, the base, balance, wind loading, cable strain relief, clearance, and the complete load path before raising or operating the antenna.

Identify the handle, CHA SS Adapter, extension, tripod interface, and base support before assembly. Similar-looking threads are not a substitute for the documented part sequence.

Carbon-Fiber Tripod Boundary

Do not install the CHA CFM-34 HD on the CHA CARBON FIBER TRIPOD. The mast is too heavy for this base path. Use the CHA SPIKE MOUNT or CHA UCM for the owner-approved CFM-34 HD support arrangement and validate the complete deployment.

Inspection and Safety

  • Matching threads establish the interface only; they do not prove structural capacity.
  • Confirm full, clean thread engagement without cross-threading or excessive force.
  • Account for antenna weight, extension height, leverage, wind area, tripod stance, soil, clamp surface, and cable pull.
  • Use feed-line strain relief so the connector and aiming position do not carry cable weight.
  • Maintain RF-exposure and electrical clearances and keep the structure away from utility wiring.
  • Lower the antenna for unsafe wind, an unstable base, a slipping clamp, damaged threads, or any uncertain load path.

Source and Claim Boundary

This article implements Chameleon Antenna owner-approved mounting policy dated August 4, 2026 and reconciles the current CHA TACYAGI-70, CHA SS Adapter, CHA UCM, CHA SPIKE MOUNT, CHA CARBON FIBER TRIPOD, extension, and CFM-34 HD records. Military, government, academy, or field use does not constitute official endorsement. A support not named here may share a thread size, but physical fit alone does not establish a documented completed-system configuration.
