EchoConnect wire

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.
