RG316 coax, shown below, is perfect for making up patch leads, building baluns and more. This 50 ohm coax is thin, flexible and will take a considerable amount of power. I’ve also bought a crimping tool. The tool is suitable for SMA plugs plus many more RF connectors.

10 2.5
30 4.3
50 5.6
100 8

I use RG316 patch leads for long, medium and short wave receivers. The loss at these frequencies, as shown by figures above, is negligible when using a couple of feet of this coax.
