I’ve been looking at some Echo products for my church and keep seeing the install instructions mentions the wiring should be “Belden 8471 or equivalent“. 
Since this Belden cable is over $1/ft, what would be a much more economical equivalent? I can’t find any specifics about the Belden cable like impedance, but would any cable capable of serial RS485 communication work? I can get that type of cable for around 30 cents a foot. 
I like the idea that you can use cat 5, but requiring a $60 termination kit for each station just kills any benefit of using cat 5.
