20-10 Meter Fan Dipole Antenna: Complete Build Guide
Description
This guide provides instructions for building and deploying a 20-10 meter fan dipole antenna. It details the construction, specifications, performance characteristics, and practical considerations for this multi-band HF antenna. The fan dipole design connects several dipoles of different lengths in parallel at a single feedpoint, allowing operation across multiple bands without switching or external tuners. Key advantages include multi-band coverage, simplified installation, cost-effectiveness, and improved efficiency. The antenna offers broadside East/West coverage and horizontal polarization at 50 ft height. Specifications include element lengths for 20, 17, 15, 12, and 10 meters, constructed with 1/2 inch PVC pipe for elements and a 2 inch PVC pipe for the 8-inch long feedpoint connector. Materials required include PVC pipes, RG-8X feedline, hardware for mounting, antenna wire, and guying rope.
