That's characteristic impedance; typical DC resistance for RG-59 is about 48 Ohms per 1,000 ft. or .5 Ohm (1/2 Ohm) per 10 ft. according to this sheet.my cable and connectors are 75 ohm

Ok so after many trials and error @bigredfish and I came to the conclusions that my current wire will not work. Unfortunately I am going to have to pull new wire and hope for the best. I have one half of a run so far but have a question for you guys.
The box of cat6 I’m using is in the attic with the wire going out to the camera. I still have to pull it into the closet where the NVR resides. What’s the best method of pulling enough wire without much waste? I assume I should have pulled the closet first but that didn’t happen. I’m guessing pull a rope or something to get a rough measurement then take that much out of the box? What’s the best advice here.
edit: also is there a particular brand of cat6 that’s better than others? I have southwire plenum right now, but may be short by the end of the job

Sorry you have to go through that.
We verified NVR power supply good, PoE ports good, NVR can recognize cameras on good known short cable, but cant get anything working over the old RG59.
It's already been said to use solid copper, no CCA (Copper Clad Aluminum).
CMP (Plenum) is OK in the attic but less expensive CMR (Riser) is OK for use in attic, walls, crawl spaces and between floors.
IOW, P can go where R is OK but the reverse is not true (no R where P is needed).
Either do the rope thing and cut the right length (plus extra) and pull in uncoiled and straight BUT it's best IMO to have someone pay the cable off the reel or out of the box to prevent kinks and twists that can damage the cable and cause issues. This latter method also keeps you from having guess and to pull off more than you really need and waste cable ($$$).
solid copper i hopeI bought a box of vertical cable cat6 plenum reasonably cheap on eBay.
Thank you all for the help and support!
solid copper i hope
I wonder if your siamese cabling was actually smaller and couldn't support the POE.
Oh nevermind that is 59.
I was thinking this was an analog from some prior all-in-one box kit and they used smaller cabling.
The other thing you could try is re-doing the connector at the end of the cable.Originally it was but I upgraded the cable when I installed them. Lesson learned I guess but now I get to try and pull new cable before the summer heat hits!
