    Yeah, I agree although I think that when I put a PL-259/SO-239 mated combo on a VNA that it was closer to 3dB at a 1 GHz. But that's been awhile back and I could be mistaken.

    But, even dropping 3dB in a SDR receiver really isn't the end of the world. If I were using it in a transmitter application I might care a bit.

    I just don't see why they aren't making these things with the proper N connector as I can't imagine it would have any impact on manufacturing cost whatsoever.

    I did buy a discone for my SDR. The Comet was worth the extra $20.00, nice finish on the aluminium. I get excellent results on 2m, 6 and 440.

    I had an MFJ discone when I first got my license. I have a Radio Shack discone now and it's not as nice but works almost as good. Not a lot of gain but it is very useful. Only problem is it's so wideband I got IMD on certain Japanese radios. I can only imagine it could be a pain with Chinese radios.
