I now further investigated Minicircuit's quite extensive offer on test cables (including the ULC, CBL, and APC series), as well as their even wider offer on interconnect cables.
I also found out this company can ship orders not only out of the US but also right out of the UK, which makes things a bit easier if you live in Europe, and ended up ordering the ULC-1M-SMNM+, which is a well-specced, 1 meter N (male) to SMA (male), very flexible cable meant for applications such as test and measurement, R&D labs, and field RF testing. It is also reasonably priced for what it is, I believe.
Looking forwards to testing that cable when it gets here, and if I feel happy with it, I might get more cables from them.
Thanks for the various input provided!
