What you really want is professionally-made LMR-240 SMA patch cables. RG-58 is total crap on 2.4ghz. The blue coax cables seem to be degrading over time. There are plenty of cable makers on-line. You just have to get the SMA gender designations correct (elsewhere on the threads here). LMR-240 by Times wire and cable will provide flawless operation and less than 1DB loss over 4 inches with good connectors. It's flexible. Poorly-made SMA jumpers can be very "lossy" at 2.4ghz. If you want the best performance obtainable, you have to go to rigid copper coax as in the picture.
