SHIPPING AND INSTALLATION NOTES
• POLE MOUNTING: Specifically designed for fixed installation on a support pole. Its iconic configuration with sloping radials ensures a low radiation lobe ideal for DX.
• OVERSIZE SHIPPING: Given the size of the original packaging containing the aluminum sections (total mounted antenna height approximately 5 meters), we strongly recommend selecting INSURED SHIPPING at checkout for complete protection against transport damage.
