Hi Jan,
Many thanks for the valuable advice..yes I think the bend radius will be the most important parameter for us.
cheers

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. Jan

hi All,
A simple question this time!
What is the best coax cable to use in a cubesat? Size, flexibility/min radius, existing space heritage, ease of applying connectors are our main design drivers - we are only using UHF and VHF so losses are not going to be too much of a problem hopefully..
many thanks in advance
