Graham,
My vote would be RG-188A/U.  See my AMSAT-IARU Link Model Rev 2.4.3; Line
Loss Tools and Tables Tab; First entry.  Use the calculator there to get
losses at various frequencies.  It's PTFE wrapped and there are SMA and SMC
connectors made for it.  Or you can solder it directly to the transmitter
output, if you are careful.  It's pretty flexible and can have about the
shortest bend radius of any coax available.  In the end, however, that might
be your biggest problem in a Cubesat - making the short bends.
