LEFS 8010 EFHW EXTRA WIRE SET · Wire Antennas
A wire radiator or wire antenna system for documented horizontal, sloping, inverted-V, inverted-L, dipole, or NVIS use.
Why operators make room for it
Put useful wire in the air without carrying a permanent tower
A field site may offer height, distance, or concealment—but rarely all three in exactly the right places.
That is where CHA LEFS 8010 EFHW EXTRA WIRE SET enters the kit. You may need a tuner on the upper portion of 15M, but this setup provides the best overall balance across bands.
That flexibility gives an operator a credible path from a compact field kit to a full-size radiator, while the official configuration still governs feedpoint, support, tuning, and safety choices.

- Best for
A field site may offer height, distance, or concealment—but rarely all three in exactly the right places.
- What else you need
Verify required height, span, insulation, load, terrain, and guying for the selected geometry
- Limitations
Preserve the documented balanced or unbalanced feed arrangement
What an operator can do
- Select a documented horizontal, sloping, inverted-V, inverted-L, dipole, or NVIS arrangement.
- Raise the wire with a support that satisfies the antenna guide's height, load, insulation, and guying limits.
- Keep balanced dipole configurations symmetrical and do not add radial or counterpoise accessories unless the guide explicitly requires them.
Complete product details
The Chameleon Antenna Extra Wire Sets offers you the opportunity to replace damaged wires for your LEFS 8010 (Lightweight End Fed Sloper) EFHW antenna, keep a spare wire on hand, experiment with different wire lengths on your antennas, or home-brew your own antenna designs. Wire sets are the same tinned copper PTFE jacket wire as furnished with our complete antennas and include a wire winder.
COMPATIBILITY NOTE FOR THE CHA LEFS 4010:
We’ve had a great question come in from one of our customers, and I wanted to share the answer with everyone since it may help others looking to expand their setup.
Can you use the CHA LEFS 8010 Wire Set with the CHA LEFS 4010 transformer to get 80M coverage?
Short answer: YES — with a few trade-offs.
You can absolutely use the LEFS 8010 Wire Set with your existing LEFS 4010 transformer in an EFHW configuration.
To make this clearer, we ran SWR comparisons. Here’s how to interpret the graphs:
- Green curve: LEFS 8010 Wire Set on the LEFS 4010 with the RFI choke at the transformer (antenna end)
- Red curve: Same setup, but with the RFI choke moved near the transceiver
- Purple curve: Original LEFS 4010 Wire Set for comparison
What this means in real-world use:
Green (choke at antenna):
- You lose the upper portion of the 15M band
- You lose the entire 10M band
Red (choke near the radio — recommended):
- You regain the full 10M band
- You only lose a small portion of the 15M band (around 21.400–21.450 MHz)
When comparing Green vs Purple, you can clearly see the trade-off:
- The 8010 wire adds 80M capability
- It slightly affects performance on the higher bands
Our recommendation:
Run the LEFS 8010 Wire Set with the RFI choke placed near your transceiver (Red curve).
You may need a tuner on the upper portion of 15M, but this setup provides the best overall balance across bands.
This is a great way to expand into 80 meters without replacing your entire system.
