    Anyone buying this unun should open it up and check how it is wired, the one I received was not wired correctly. The toroid is wound correctly, three winding of nine turns with the end of the lower end of one winding cnnected to the top of the second winding, but the whole toroid was not wired to give the required 9:1 unun, with the end of one winding not connected to anything and the third winding just wired between the input and output sockets. It can easily be rewired to give the expected unun, I would recommend checking with aGoogle search the correct wiring for a 9:1 unun and resoldering the wires.

    Yes, I set 5 stars for every groups, BUT my product is unusable because the wiring is not ended or false done. I have to verify, or rebuild the toroid and wired. I think I did unlucky on that product. See picture attached

    The 3 (trifilar) windings are wrongly connected, e.g. one winding from input to centre of coax socket, therefore open circuit between ground an d centre pin of bnc socket. Nevertheless, the value of the components used is worth the low price of this product.
