An 80-10 end-fed half-wave antenna can be a very good performing part of an HF station. But its performance depends heavily on a well-designed and carefully constructed 49:1 unun, which matches the long wire impedance to within tuning range of operation. But the perfor-mance of an end-fed antenna is also very dependent on height above ground.

The advantage of a voltage unun is its ability to easily match impedances, unlike a current un-un, which uses an isolation transformer to balance its input and output current, but suffers from impedance matching ability.
24 sty 2024 · An Unun, short for Unbalanced to Unbalanced, is a type of transformer used in RF antenna systems to match impedance between an unbalanced antenna and an unbalanced transmission line. It is designed to convert the impedance of the antenna to a value that is better suited for the transmission lines.
