Setup Instructions
- Prepare Antenna Wire:
- For 4-band operation, prepare a 1.5-2.5 square millimeter wire approximately 20 meters (65.6 feet) in length.
- For 8-band operation, prepare a 1.5-2.5 square millimeter wire approximately 40.8 meters (132.5 feet) in length.
- Connect Antenna Wire:
Attach the prepared antenna wire to the designated terminal on the balun. Ensure a secure connection. For optimal stress relief and to prevent wires from touching, consider using zip ties or similar insulators if connecting to the top loops, as the wing nuts may not provide sufficient strain relief for long wires.

- Mounting the Antenna:
The antenna requires suspension from a mast or a sturdy tree. Ensure the installation height is at least two meters (approximately 6.5 feet) above ground for effective operation. The compact and lightweight design allows for easy deployment in various outdoor settings.

Maintenance
To ensure the longevity and optimal performance of your antenna, consider the following maintenance tips:
- Weatherproofing: While the housing has an integral rubber grommet, for enhanced weather resistance, it is recommended to apply a bead of RTV sealant along the edges of the housing when assembling or inspecting the unit. This can prevent moisture ingress over time.
- UV Protection: The antenna housing is made of ABS plastic, which may degrade over time with prolonged exposure to ultraviolet (UV) radiation. If the antenna is permanently installed in direct sunlight, consider additional UV protective coatings or shielding to extend its lifespan.
- Connection Checks: Periodically inspect all connections (antenna wire, coaxial cable) for corrosion or looseness. Clean and re-tighten as necessary.
- Physical Inspection: Regularly check the antenna wire and balun housing for any physical damage, fraying, or cracks. Address any issues promptly.
Troubleshooting
If you encounter issues with your GOOZEEZOO End Fed Half Wave Antenna, consider the following steps:
- High SWR:
- Check all connections for tightness and proper contact.
- Verify the length of your antenna wire matches the recommended specifications for the desired band.
- Ensure the antenna is installed at an adequate height and clear of obstructions.
- Inspect the coaxial cable for damage.
- No Signal or Weak Reception:
- Confirm the antenna is properly connected to your radio.
- Check for continuity in the antenna wire and coaxial cable.
- Ensure your radio is tuned to the correct frequency and mode.
- Interference:
- Ensure proper grounding of your radio equipment.
- Consider adding a common mode choke at the feed point if experiencing RF interference with other electronic devices.
