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.

#1 I have a long (random) wire antenna that feeds into the house with coax. Should a balun be best used between the long wire and the center conductor of the coax or between the coax center conductor and the receiver? I use one of the original SDR Play receivers.

Ron's Radio Corner Balun for long wire antenna

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.

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.
