Belden Pressure Fit BNC


Does anyone have any experience with this BNC? Pressure fit connectors are normal for 75 ohm, this is for 50 ohm
Please note that the specs make use of a RG 223 iffy. The diameters of 223 are slightly larger than the specs of the connector.
Connector specs:
center pin: .0317-.0339
OD: .185-.201

Belden 223 specs:
center pin: .034
OD: .212

Belden RG 58 does fit the specs, but I would like to use something better, I normally use RG 223.

Any suggestions?

You *might* be able to use it with RG-223 the center conductors are pretty close in diameter, but the additional shield increases the overall diameter from .195 to .210 so getting it onto the cable will definitely be a fight. Maybe you can drill out the inside of the connector compression sleeve to fit the coax better if you can find the just-right size drill bit.
I've got lots of RG58 that I use for my test equipment, so I'll probably get some to try out. I use compression connectors exclusively for my RG-6QS cable TV wiring because I find them easier and more secure than the crimp connectors, plus they're water-tight.

That's what I thought also.
I was just intrigued by the compression fit, I really like the idea. I have been looking for such a fitting for a while.
Now there is one. Let me know if you try it. I might just invest in the tool and a few BNC connectors, but it would be nice to have some positive input on the device. I suppose going to really good RG 58 stuff might be necessary.
