Topband: Replacing F Connectors with BNCs

[Bill Wichers]

There are higher-quality F female connectors with a blue dielectric insert (not the normal white or clear insert). They are rated up to 2GHz if I remember correctly, but they also have better machining on the threads and a better center conductor terminal. The male connector isn't really any difference. The blue ones I've seen have also been longer but I'm not sure if that's always the case.

If you need a "better" F female I'd try the ones with the blue inserts. They're available from many different sources. I don't know if they can handle repeated disconnect/reconnect cycles better, but the terminal inside them is much more robust.
