   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.

   Manual 1:9 UnUn for long-wire antennas. The 1:9 UnUn is wrongly called a 1:9 BalUn in many sources. In my opinion, this is incorrect because there is no transformation to a balanced antenna system. The feed point of a long-wire antenna is nothing more than a broadband impedance transformer.

   Long-Wire Antennas. Long wire antennas are typically horizontal antennas, fed at one end, and well over 1/2-wavelength long at the lowest operating frequency.
