MIL WHIP CORD-SPRING · Radiators & Extensions
A modular radiator, whip, or extension used inside a documented antenna configuration.
Why operators make room for it
Give a modular antenna the length its configuration calls for
A small change in radiator length can open a different configuration without forcing the operator to carry a completely separate antenna.
That is where CHA MIL WHIP CORD-SPRING enters the kit. To start, remove the tip and base cap and remove the broken spring and cord assy. If the spring is corroded clean out the interior of the base section.
Used in a documented configuration, the component gives the operator another practical build option while preserving the electrical, mechanical, and power limits of the complete system.

Key Specifications
- Product type
- Radiators & Extensions
- Primary role
- A modular radiator, whip, or extension used inside a documented antenna configuration.
- Electrical role
- Determined by the part's documented position in the completed antenna
- Compatibility
- Physical fit alone does not prove RF or structural approval
- System position
- Install only in the electrical or mechanical position defined by the completed-system guide
- Interface rule
- Shared 3/8-24 fit does not by itself establish RF, power, or structural compatibility
- Required companions
- Base, loading, feedpoint, mount, support, and radial / counterpoise choices are configuration-specific
- Operating coverage
- Determined by radiator length, loading, tuner, and completed configuration

- Best for
A small change in radiator length can open a different configuration without forcing the operator to carry a completely separate antenna.
- What else you need
Combine it with the specified base, loading, feedpoint, mount, support, and radial or counterpoise system.
- Compatible with
- Physical fit alone does not prove RF or structural approval
- Shared 3/8-24 fit does not by itself establish RF, power, or structural compatibility
- Limitations

What an operator can do
- Use the part as an electrical radiator or mechanical riser only in the position documented by the completed-system guide.
- Combine it with the specified base, loading, feedpoint, mount, support, and radial or counterpoise system.
- Treat a shared thread as physical fit only; verify RF, power, and structural compatibility from an approved configuration.

Mil Whip Cord-Spring
Replacement Cord-Spring for Mil Whip 2.0
Replacement Instructions:
To start, remove the tip and base cap and remove the broken spring and cord assy. If the spring is corroded clean out the interior of the base section.
Start threading the new cord through the base section and through each successive whip section until the cord exits the top section with the whip fully erected. Replace the base cap.
Exercise the spring to confirm proper function.
With all sections fully seated pull out 6-8 inches of cord and clamp right at the tip using the clamping pliers of choice.
Tie a simple overhand knot in the cord and secure at the tip. Remove the clamping pliers and cut off the excess cord leaving about 1/8” extra. Melt this extra cord to prevent fraying.
Replace the tip cap to complete the procedure.
Tools Needed:
New cord and spring assy.
Small vise grip or other locking pliers
Knife or cutter to trim excess cord
Heat source to melt the tag end of the cord
A vise or someone to assist in holding the whip
