Is crimping better than soldering ?
That was my question...
Well, if you ask me, the answer is this: if done professionally, a crimped connector can be just as good as a soldered one. The worst thing you can do is buying the cheapest junk connectors in the crimp version. I have once made a bunch of lab cables, using standard RG58 and cheap noname crimp connectors. Most of them have developped contact problems sooner or later. By contrast, all my soldered ones have worked well even after 10+ years.
Last time I needed a bunch of new cables in various lengths and with different connectors - yes, it was when I introduced the Hyperflex 5 in my lab, I didn't take a chance and ordered the cables custom built from Koaxshop 24 - but they don't seem to carry the Hyperflex anymore, which is a pity, because it has the best electrical characteristics overall amongst all those "low loss" cables which are still usable in a lab (you don't want anything thicker than 5 mm and you also don't want anything more rigid than the Hyperflex 5 for sure).
