In plain language: CHA LEFS 4010 Product DNA: Complete System Overview keeps the entire CHA LEFS 4010 signal path visible so the customer knows what is included, what is required, and what can be expanded safely.

A customer should be able to see the complete antenna before buying: the radiator, transformer, feed line, return path, support, and what the package does not include.

The CHA LEFS 4010 puts a full 65 ft HF radiator into a compact 1.1 lb package for operators who would rather carry antenna wire than a heavy support system. Its integrated end assembly combines the suspension point, line winder, 49:1 matching network, and both EFHW and dipole feed connections.

What matters for this decision

  • For POTA, SOTA, hiking, biking, and temporary HOA operation, its strongest advantage is a complete resonant field workflow: raise the feed assembly, pull out the wire, connect the supplied choked RG-316 when that variant is selected, and operate four popular bands without stopping to adjust the antenna.
  • End assembly with integrated line winder, 49:1 network, EFHW connection, and dipole connections.
  • One 65 ft, 20-gauge antenna wire with terminal lug, carabiner, and far-end insulator loop.
  • Depending on the selected product variant, 25 ft of RG-316 with an integrated RFI choke and BNC connectors.
  • Storage pouch. Paracord, stakes, and field supports remain installation choices unless the selected listing says otherwise.
  • Use the current product listing to confirm the exact purchased variant and package contents.

Why operators choose this system

For POTA, SOTA, hiking, biking, and temporary HOA operation, its strongest advantage is a complete resonant field workflow: raise the feed assembly, pull out the wire, connect the supplied choked RG-316 when that variant is selected, and operate four popular bands without stopping to adjust the antenna.

Published operating reference

  • Published bands without a tuner: 40, 20, 15, and 10 meters.
  • Published tuner-assisted bands: 30, 17, and 12 meters.
  • Published power: 100 W SSB, 50 W CW, and 25 W digital or other modes.
  • Published size: 65 ft wire, approximately 1.1 lb, one-operator setup around 10 minutes.

Make the next deployment repeatable

Record product revision, configuration, wire dimensions and bearings, endpoint heights, support hardware, return path, coax and choke condition, tuner state, analyzer reference plane, weather, and on-air reports.

Boundary: The optional dipole arms are separate resonant configurations. The 65 ft EFHW wire, the optional dipole sets, and the LEFS 8010 or LEFS FEATHER are not interchangeable merely because they belong to the same product family.
Keep the current guide with the station.

This lesson explains the operating choice in plain language. The current guide still controls assembly, dimensions, power limits, and safety.
