Chameleon Antenna CHA SKYLOOP 2.0
CHA SKYLOOP 2.0 Horizontal Full-Wave Loop Antenna
Instruction Manual
1. Product Overview
The CHA SKYLOOP 2.0 is an extreme performance horizontal full-wave loop antenna designed for amateur radio operations. This antenna offers significant advantages over traditional dipole antennas, primarily through reduced background noise and enhanced signal gain, resulting in stronger received signals.
It is engineered to operate across a broad frequency range from 3.5 MHz to 54 MHz, encompassing the 80-meter through 6-meter amateur bands. Its integral broadband impedance matching network transformer facilitates wide-range antenna tuning without the need for constant adjustments when used with a suitable antenna tuner.
2. Components
The CHA SKYLOOP 2.0 antenna system includes the following primary components:
- Approximately 265 feet of 16-gauge antenna wire.
- Insulators for wire support and isolation.
- A matching transformer unit for impedance matching.

3. Setup and Installation
Proper installation is crucial for optimal performance of the CHA SKYLOOP 2.0 antenna. This antenna is a 265-foot full-wave loop cut for the 80-meter band.
3.1 Site Requirements
- A minimum clear area of approximately 60 feet by 60 feet (18.3m x 18.3m) is required to properly install and support the antenna.
- The antenna should ideally be installed at a height of 30 to 40 feet (9.1m to 12.2m) above ground for maximum performance. While it can function at a minimum height of 10 feet (3m), higher installations yield better results.
- The antenna requires four evenly spaced support points for suspension. These points should be robust enough to bear the tension of the antenna wire.

Ensure all connections are secure and weatherproofed as necessary to prevent moisture ingress into the matching unit or coaxial cable connections.
4. Operating Instructions
The CHA SKYLOOP 2.0 is designed for broad frequency coverage with the assistance of an antenna tuner.
- Connect the antenna's matching unit to your radio equipment using a suitable 50-ohm coaxial cable.
- Utilize a wide-range antenna tuner to achieve optimal impedance matching across the desired operating frequencies. The antenna is capable of covering all amateur bands from 80 meters (3.5 MHz) to 6 meters (54 MHz) when paired with an appropriate tuner.
- Perform SWR (Standing Wave Ratio) checks to ensure efficient power transfer and minimize reflected power. Adjust the antenna tuner as needed for each operating band.
The inherent design of the horizontal loop antenna contributes to reduced background noise, enhancing the clarity of received signals.
5. Maintenance
The CHA SKYLOOP 2.0 antenna is constructed for durability and requires minimal maintenance. Regular inspections are recommended to ensure continued performance.
- Periodically inspect the antenna wire for any signs of wear, fraying, or damage, especially after severe weather conditions.
- Check all connection points, including the coaxial cable connection to the matching unit, for corrosion or looseness. Clean and re-secure connections as necessary.
- Ensure that the support points and insulators are intact and providing adequate tension and isolation for the antenna wire.
- Keep the matching unit enclosure clean and free of debris. Do not open the matching unit unless you are a qualified technician.
6. Troubleshooting
If you experience issues with your CHA SKYLOOP 2.0 antenna, consider the following common troubleshooting steps:
- High SWR: Check all coaxial cable connections for proper seating and continuity. Inspect the antenna wire for breaks or shorts. Ensure your antenna tuner is functioning correctly and is properly adjusted for the operating frequency.
- Poor Reception/Transmission: Verify that the antenna is installed at an adequate height and clear of obstructions. Confirm that your radio and tuner settings are correct for the band you are operating on.
- Increased Noise: While the loop design reduces noise, external electrical interference can still occur. Check for nearby electrical devices or power lines that might be generating noise.
- Physical Damage: Visually inspect the entire antenna system, including the wire, insulators, and matching unit, for any visible damage.
If problems persist after performing these checks, contact Chameleon Antenna customer support for further assistance.
