) use the standard compression tools used for the standard Cable-TV F connectors. They're commonly used for CCTV or home theater installs, but work great for BNC scanners. The ones I linked to are simply to show you what's available so Google "BNC Compression Connector" to help find the best price, etc.
Also instead of simply color coding the cables, get one of the label makers and some clear shrinkable tubing. That way instead of remembering that the short yellow with long pink is the living room you can simply read the label (the clear tubing is simply to protect the label from dirt and prevent it from working loose/falling off).
My setup was actually like that some time ago. Im not saying in anyway that your suggestions are not good. They are in fact what I had initially done to get my radios set up. I changed from that setup to what you currently see in the above pic. I changed for a few reasons:
1. I actually have a Brother label maker that I used to label all pigtail ends with. It worked fine, but I found myself picking the wrong one anyway when assembling my radio hutch together because all the labels were "white" in color and all looked the same anyway when reaching from behind a shelf to connect. All pigtails come from the same place, but not all are the same length. So switching them back and forth was trial and error in some cases. I found the colors to be a lot more beneficial in quicker identificationI(although I dont seem to be back there all the time anyway).
2. I couldnt find crimp style connectors with the center dielectric foam surround that I wanted to have.
I used to use crimp style connectors on all my connections. But I didnt have enough when I switched from 8way to 16way. So i used an extra pair of these twist-ons. I noticed a small but significant difference in the amount of noise and lack of spurious signals coming in on a particular radio. That one radio had the only assembled pigtail with the twist-on BNC's.When I switched the cable to the crimp-on the noise and spurious activity was back. I moved the twist-on set to another radio, and the same results. My squelch settings got tighter and the spurious activity decreased. Same RG-6/Quad from the same spool, just different connectors. I dont exactly know the science behind it, but I switched all my connectors over to the twist-ons and experienced much better results on all my receivers. Im guessing
that that missing center dielectric foam in the middle has something to do with it.
I had a hard time trying to find crimp-ons with the center foam for RG-6/Quad. There are a few out there, but were expensive or I had to buy in huge bulk, and/or it took 6-8 weeks delivery from overseas.
This pic shows the Twist-on BNC on the left and the Crimp-on style BNC on the right.
Im sure you can all see the difference - I can hear it!
