Build Resonant Feedline Dipole Antennas
Find construction projects and design information for resonant feedline dipole antennas across various amateur radio bands.
Resonant Feedline Dipoles (RFD) are a practical antenna choice for many ham radio operators, especially those needing a simple, effective solution for single-band operation. These antennas use the feedline itself as part of the radiating element, simplifying construction and often making them very portable. Hams often build RFDs for specific bands, from HF like 40 meters and 10 meters, up through VHF bands such as 2 meters and 4 meters, making them versatile for various amateur radio activities.
Many operators find RFDs ideal for quick deployment in portable operations, field days, or even as a stealth antenna. Projects often detail the construction process, including cutting precise lengths for the radiating elements and the feedline to achieve resonance on a target frequency. Resources in this category provide practical guidance for building these antennas, with examples for bands like 10 meters and 2 meters, helping hams understand the design principles and construction techniques for their own antenna projects.
