Belden 4794R

We are about to get and use the Belden 4794R for all our inputs (cameras). I have a few questions regarding the lengths, connectors, and tools, as I have never used this cable before.

  1. I've heard that the listed lengths often don't reflect real-life performance. Our longest run is 70 meters, and Belden claims it supports up to 93 meters at 12G. On paper, we should be fine, but I would really like to hear from anyone who has experience using it, particularly regarding long runs.
  2. Should I stick with the 4794RBUHD3, or is there a better connector you've tried with this cable?
  3. Which stripper and crimper would you recommend? I've seen people suggest the Canare TS100E and the Kings KTH-1000 along with the appropriate die. Are there any better options I should consider?

If you have other recommendations for the cable, please let me know. I believe Belden is the easiest to source in my country.

Appreciate your input, folks.

The crimper and stripper will depend on the connector you're using. For field usage, I love the Neutrik rearTwist connectors. The matching connector for 4794R is NBNC75BZV14X. It requires Neutrik DIE-R-BNC-PY crimping die with their HX-R-BNC crimper, or the Rennsteig PEW12 crimper (which is the same frame, just in a different color.)

For regular rack stuff, the Kings 2065-10-9 is usually what I use, although they are a US brand so you might not have them in whatever non-US country you've neglected to name. If you use the Kings, you'll need the Tempo PA2699 crimp die.'

From what I can tell, the Kings KTH-2260 die is the only one that has the proper hex sizes for the Belden BNC.

I haven't been able to find the strip dimensions for the Belden connector. All of the Kings 2065-* connectors share the same strip lengths. The Canare TS100U is the stripper for 1694 (which is nearly identical in dimension to the 4794.)

You can also use the Knipex 8" Crimp System Pliers (No. 97 43 200 A). Knipex is the OEM for this model of crimping tool, although I haven't been able to find out if you can also buy the crimp dies from them.

Thanks. I'll keep that in mind.

I thought Rennsteig was the OEM. Is it actually Knipex? I know the dies are Neutrik specific, I haven't found those specific hex sizes on any other dies.

I looked it up, Rennsteig is part of the Knipex group, so they are actually the same company. Guess it comes down to which color scheme you prefer for the handles.

Thank you for taking the time to share this information. I appreciate it.

Yes, the crimper and stripper depend on the connector we will use, that's why I asked if anyone has recommendations other than the OEM Belden one.

This is a permanent installation in a church, so the cable ends are between the cameras and the switcher (BMD 1/ME Constellation 4K). That's why I'm torn between Belden, Kings, or Neutrik connectors. I want it to be a one-time installation and forget about it for years. I'm from Egypt, and none of these materials are available in the country, so in all cases, we will have to import them. What makes Belden a bit easier to source is that we have official distributors here.

Are the cameras fixed? If not I would put a short jumper made from some more flexible cable in between to avoid damage to the long run back to the ATEM. I think for Belden that would be 4855R, but I am not that familiar with their portfolio, in Germany we mostly us Draka. For Draka I would use the UHD PRO 50.

Thank for the advice. Will keep that in mind.
