Transmission lines — Technical Articles

The Transmission Lines Knowledge Base focuses on the backbone of every RF system: coax, open-wire, and connectors. These articles cover losses, SWR behavior, shielding myths, and connector choices, all backed by engineering analysis rather than folklore. Each entry is datestamped so you can see when it was last validated or updated.
