The feed point of a long-wire antenna is nothing more than a broadband impedance transformer. In the case of a 1:9 UnUn, the power line (coax) impedance of 50 ohm will be transformed up to an impedance of 450 Ohm. After all 50 x 9 = 450.

A 9:1 unun is a transformer that reduces the impedance at the input by a factor of 9. So, if you connect a length of wire that presents an impedance of about 450 Ω to the input, you'll get an impedance of about 50 Ω on the output. In fact, the 9:1 unun that I built is actually an autotransformer.

These are sometimes known as a Magnetic Longwire Balun. Its really an impedance transformer (9:1) to feed a high impedance, end fed (unbalanced) random wire which is likely to be a few hundred ohms, and transform it into something closer to a 50Ω (unbalanced) coaxial input, hence UnUn.

Description This design is excellent for matching both long and short length unbalanced long wire antennas for multiband use and will allow the internal tuner of most rigs to match a single long wire antenna. This unit utilizes stacked cores for increased power handling and added inductance for the better performance on the lower frequencies.
