Two manufacturers; Belden is U.S. and Canare is Japan.
Belden is widely available and I've found more distributors that stock colors and will cut small lengths. One said Belden is easier to work with. I corresponded with Belden mgmt and they said they recognize and value the small installer/fabricator. Both companies have premium cables that professional broadcasters use and in a HT environment you'd be hard pressed to hear/see a difference between their premium cables. Here's a distributor I found that has good service/advice and cuts/sells small lengths: http://www.josephelectronics.com/jos...age&Width=1024
