Remember to cut the track if you want an unun!
That's the headline. Make sure you use it in the right configuration. For a random wire antenna you want to aim for a 450 Ohm resistance at your chosen frequency dips, so that it transforms down to 50 Ohm. Don't use a half-wave at a chosen frequency!I am not sure why a 9:1 would be useful as a balun, as a loop would be more 4:1, but if you don't cut the track underneath it stays in a balun configuration.You can also transmit through these, not very much, but you can. 0.25W is the rated maximum for the transformer on the PCB, which is enough for WSPR. I managed to get out quite far with this, but definitely don't push it too high and keep your volume levels down to get the desired power.

Very good 1:9 balun
Well made and works well.Would prefer a thicker PCB to be used, as this one is quite thin and flexes.
