AUDIO - prox 100 ft Belden 9451, and 40 ft x Southwire ES7497. Also avail - a few hundred feet of ¼" Techflex used as a common out jacket for bundling audio and/or cables together.
VIDEO - mini-RG59, many pieces already terminated with a BNC connector on one end. Will accept any reasonable offers. I also have a nice set of video cable fabrication tools avail - made by White Sands Engineering, for pro-standard compression fittings.
I was a video pro for 30 years, and refined my equipment by making my own custom cable assemblies. I am happy to give you my ideas about how to do this for faster and more accurate field setups. I don’t need the knowledge any more! Price is negotiable. $40 OBO.
