WARC-D · 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
Shape the antenna around the site—not the other way around
Wire antennas reward the operator who can read the site and choose a practical geometry before the first line is thrown.
Introducing the CHA WARC-D (Dipoles) from Chameleon Antenna, specifically designed to complement the versatile CHA LEFS 4010. The CHA LEFS 4010 features a dual input system, allowing seamless integration with both end-fed and dipole antennas. The CHA WARC-D covers three crucial WARC bands: 30M (Orange), 17M (Yellow), and 12M (Blue).
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.

Product Description for CHA WARC-D (Dipoles)
Introducing the CHA WARC-D (Dipoles) from Chameleon Antenna, specifically designed to complement the versatile CHA LEFS 4010. The CHA LEFS 4010 features a dual input system, allowing seamless integration with both end-fed and dipole antennas. The CHA WARC-D covers three crucial WARC bands: 30M (Orange), 17M (Yellow), and 12M (Blue).
Why the CHA WARC-D Complements the CHA LEFS 4010
- Enhanced Frequency Coverage: The CHA WARC-D expands the frequency capabilities of the CHA LEFS 4010, ensuring superior performance on the WARC bands which are essential for serious DXers.
- Improved Signal Quality: By using dedicated dipoles for each band, the CHA WARC-D offers optimized signal clarity and reduced noise, significantly enhancing communication efficiency.
- Flexibility in Operation: The dual input system of the CHA LEFS 4010 allows for quick switching between end-fed and dipole configurations, offering operators maximum flexibility in various operating conditions.
- Efficient Band Management: With separate dipoles for 30M, 17M, and 12M, the CHA WARC-D ensures minimal SWR and efficient power usage, improving overall antenna system performance.
Technical Benefits
- Targeted Band Performance: Each dipole is specifically tuned for its designated WARC band, ensuring peak performance and minimal interference.
- Durable Construction: Built to withstand diverse environmental conditions, the CHA WARC-D ensures longevity and reliable performance in field operations.
- Ease of Setup: The CHA WARC-D is designed for straightforward installation and integration with the CHA LEFS 4010, making it a user-friendly addition to any amateur radio setup.
Usefulness of 30M, 17M, and 12M Bands in Amateur Radio
- 30M Band (10.1-10.15 MHz)
- Usage: Primarily used for digital modes and CW (Continuous Wave).
- Benefits: Provides excellent propagation characteristics during both day and night, making it ideal for long-distance communications (DX) with minimal interference. However, it is not used for voice communications or contesting.
- 17M Band (18.068-18.168 MHz)
- Usage: Popular for SSB (Single Side Band) and CW.
- Benefits: Offers stable propagation conditions with less crowding compared to other bands. Useful for mid-range and long-distance contacts, particularly effective during daylight hours. This band is not used for contesting, providing a quieter environment for regular communications.
- 12M Band (24.890-24.990 MHz)
- Usage: Utilized for SSB and CW.
- Benefits: Known for its higher frequency, providing good DX opportunities especially during periods of higher solar activity. Less populated, allowing for clearer communications. Like the other WARC bands, it is free from contesting activities.
The CHA WARC-D is the perfect enhancement for the CHA LEFS 4010, providing amateur radio enthusiasts with expanded capabilities, improved signal quality, and unmatched operational flexibility on the WARC bands.
Additional Information on Band Usage
The 30M, 17M, and 12M bands, also known as WARC bands, are reserved by international agreement to be free from contesting activities. This ensures that these bands are quieter and less congested, making them ideal for casual and long-distance (DX) communications. They are particularly valuable during periods of high solar activity when propagation conditions are optimal.
The antenna system consists of: 1 X 12M DIPOLE (BLUE 20 GAUGE Tinned Copper PTFE (Teflon) (-70°C to 150°C)
1 X 17M DIPOLE (YELLOW 20 GAUGE Tinned Copper PTFE (Teflon) (-70°C to 150°C)
1 X 30M DIPOLE (ORANGE 20 GAUGE Tinned Copper PTFE (Teflon) (-70°C to 150°C)
