I’m working on building the Ultra Probe and am coming along quite well. I know the amplifier works, but do not have it in the box yet. I have the probe complete except for the input fet and the BNC connector attached. I’m using some rg400 coax, but have never placed a connector onto it. Looks like the available connectors are crimp on. I do not have a crimper for this. Since I do not have much use for a crimper like this, is there a way to install the connector with out it?
@mike-zahorik I have ran into that before as well. Didn’t want to spend big money on a crimp setup for the low amount of them I would do. I was using some coax that is similar to RG6 size. There was a connector kit on mouser that was a compression style with a soldered center pin, it worked good and was pretty easy to build but I am not sure if it is available for smaller coax. Honestly I don’t see why you couldn’t solder on a crimp pin the same way, just have not tried that before. That is all the experience I have with them. I picked up an amazon kit for regular F connectors but haven’t used it yet to know how well it works, maybe look for something similar with BNC?
Radios + Tubes + Scopes + Cars= Nothing better!
@radtekman Thanks for the reply. Mouser and DigiKey both have crimpers, but they are pricey. Thought of trying to solder the center pin and making a die for the ferrule that I could use in a vise, but just yesterday I found a crimper on eBay and thought I’d go on a flyer to see if it would work.
The crimper came today and seems to work OK. Had to experiment with how much to strip off the Coax and which crimp slot to use, but this tool should work with other BNC and Rg’s.
