F-connector vs. BNC

pooge · 2nd August 2006, 12:08 AM

Is there any good reason why a BNC should be preferred over a good quality F-connector for transferring digital audio? I'm talking about a GOOD F-connector, i.e., 3GHz barrel rated at greater than 25db return loss, compression vs. crimped male, etc. From the specs I've seen, these F-connectors have better shielding than a BNC. So why not use them instead of BNC?

...just make sure you get a 75 ohm BNC. Most are 50 ohm. If you were choosing between high quality, I don't think there'd be a difference. Canare makes really nice versions of both

a BNC connector won't fall off.

I don't think Canare makes a compression F-connector. They a crimp connectors.

How does an F-connector fall off?

I hate F connectors -- the bare copper can get oxidized over time. I think they are prinicpally used because the connection is quick and inexpensive to make -- no fiddling with a center conductor which has to be soldered. The consumer VCR/Cable Box F-Connector will always come loose, but I doubt it's a problem for the screw type.

The Canare "F"'s don't suffer the oxidized copper problem. They use a tightly crimped, gold plated pin.

....machined threads too. They're pretty sweet.

F-connectors are more suitable for a permanent installation. I haven't worked with the Canare F-connectors, but you don't want to disconnect a normal F-connector too often.
