Plain-language answer: An end-fed antenna is driven near one end of its radiator, usually through a matching network and an intentional or distributed RF return path.
Why it matters at the radio
The convenient feedpoint can simplify deployment, but voltage can be high and the coax shield may become part of the return unless the counterpoise and choke strategy are controlled.
What to watch in the field
Follow the product’s radiator length, transformer, counterpoise, choke, and feed-line recipe. Check whether coax movement changes tuning.
The common misunderstanding
Believing “end fed” means the antenna operates without a return conductor.
Learning boundary
This lesson explains established radio and antenna practice. Current regulations and the exact equipment or antenna guide control legal limits, ratings, compatibility, and safety.
