This week, we’ve gathered some practical insights covering a range of topics, from antenna construction to portable power solutions. There’s a solid piece on building a Fan Dipole Antenna – 80 to 6 meters, which is always useful for those looking to get multiple bands out of a single feedline. For the low-band enthusiasts, we found an interesting look back at a Yagi 2 Elements on 80m Band from a 1976 Radio REF issue—a reminder that some challenges, like large antennas, are perennial. We also have a guide for those considering a 5 Band Quad Antenna Design Guide, a project that can significantly improve station performance. And for field operations, a detailed guide on Building a LiFePO4 Battery Pack for Emergency Power offers a robust alternative to lead-acid. Finally, a document on 64 to 1 Antenna Matching Auto-transformer provides a deep dive into impedance matching, something that comes up often when optimizing less-than-ideal antenna setups.
This PDF guide offers comprehensive instructions and diagrams for constructing a fan dipole antenna. It covers design principles, material selection, and installation procedures, making it a valuable resource for hams aiming for effective multiband operation.
This PDF document provides in-depth information on small loop antennas for amateur radio. It details their design, construction, and practical application, offering tips to optimize performance in various operating environments.
This guide provides detailed information for designing a 5 Band Quad Antenna. It covers necessary materials, dimensions, and construction steps, helping hams optimize their antenna setup for maximum performance across five different bands.
This guide details the construction of an 8AH 12V LiFePO4 battery pack suitable for emergency or field power. It highlights the advantages of LiFePO4 over lead-acid batteries, discusses safety considerations, and explains BMS integration.
This article from a 1976 Radio REF issue discusses large antennas for low bands, specifically focusing on a 2-element Yagi for 80 meters. It details the antenna's construction and functionality, including its switchable directivity.
This PDF document provides information on a 64 to 1 antenna matching auto-transformer. It likely includes details on how to build or use this specific device, which is useful for hams optimizing their antenna setup for improved efficiency.
