Plans for a well-performing terminated folded dipole. A TFD is a good choice for an antenna when one needs to prioritize bandwidth matching over ultimate performance. A TFD will lose roughly 30% of its transmit performance to heat via resistance but can be operated without a tuner across almost the entire HF band. This is particularly helpful for sharing one antenna with multiple radios using diplexers/triplexers or when doing frequency-agile work like Automatic Link Establishment (ALE). There are some good articles on TFD performance and trade-offs going back to the 1940s.
SARA used a TFD to great result in Field Day 2021 with five radios connected through a filter system to share one antenna. Here are the plans for that antenna as has been requested by many people.
