Sloper
Raise the far end 25-40 ft where one useful elevated support is available.
Lightweight 65-foot end-fed half-wave HF antenna
Full-size HF wire without full-size field baggage
Put 65 feet of useful HF radiator in a 1.1-pound field package.
CHA LEFS 4010 puts a full 65-foot HF radiator into a field package weighing about 1.1 pounds. Raise it as a sloper, inverted V, inverted L, horizontal wire, or low horizontal NVIS antenna when a permanent tower or full-size base installation is not practical.
The supplied EFHW wire covers 40, 20, 15, and 10 meters without changing the radiator. A suitable tuner expands practical operation, while optional LINK-D, LINK-D15, and WARC-D wire sets turn the same end assembly into documented resonant dipole configurations.

How the complete system goes together
Use this official visual to understand the product’s scale, component order, and documented deployment paths before choosing a configuration.
Choose the deployment, not just the hardware
Documented ways to use this system
Each card describes a complete guide-controlled path. Connector fit alone does not create another supported configuration.
Inverted V or L
Use the floating isolation ring and available supports to fit the controlled 65-foot wire into the site.
Horizontal / NVIS
Use a horizontal deployment for broadside coverage or the guide's low-height regional/NVIS path.
Configuration boundary: the 65-foot EFHW and each optional dipole wire set are different complete radiators. Use the exact supported wire, link positions, feed arrangement, height, and geometry before applying a pattern or SWR reference.
