    When the balun arrived, it rattled inside. Disassembly showed that 2 nuts and a washer were floating loose inside. Actually trying to use this balun could have been disastrous. I will repair it just because as an electronic tech, thats what I do, and I enjoy the challenge. Basically, for most folks... buyer beware!

    Matching 450 ohm ladder line into a short length of coax for use with an auto tuner. Works great with a 160 meter dipole. Should have done this years ago.

    It appears to work OK, and I did not have to return it for repair, if you know what I mean..
