Balun Unun interesante para experimentar pero poco más
Balun Unum para experimentar en SDR con antenas de hilo, pero poco más. Realmente para temas de HF, MF y LF hay soluciones en SDR mejores como las antenas Youloop, activas y pasivas. Eso si, funcionar funciona, pero necesitarás mucho espacio libre para poder tender los hilos.

Good buy
The added connectors come in handy when you move your sdr setup a lot, I tavel with one and this eliminates a lot of my improvising. Works well.

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.

Does a great job at an affordable price.
I purchased this balun and constructed a 40m horizontal dipole antenna, and I cannot say a single bad thing about it. Does its job like it should and a great price. Only thing I wish was different is it would be cool if it either came with an enclosure or nooelec offered one for it. But hey nothing a little ingenuity can't take care of.
