ANTENNA LONG WIRE CON BALUN 9.1 By IT9HBX IT9HBX
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.

I'm using a Nelson Antennas 9:1 balun end-fed 71 foot wire, about 4 metres above ground from a difficult urban back yard.. The wire is 84.5 foot long, in an inverted L configuration. I put it up 8 days ago, and have worked 38 countries on 5 of 6 continents. Still lacking oceania, but not bad for a week! Best DX being Mongolia to the East.

#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.
