SMA Female to SO-239 Jumper for your Wouxun HT

The Comet SMA Female 18" coax adapter jumper to SO-239 for Wouxun Radios looks like a better option than the jumper I bought on ebay. It is actually cheaper (at $14) than the one I purchased on ebay and I would hope that this one would not have the problem of the sheath pulling away from the SMA connector.
