Topband: beverage support spacing

[Ray, W Marty]

Good news! I got permission to use the field behind my house to install winter beverages. Now for the fun stuff. I searched the archives for info on  beverage support types, but did not find much discussion on that topic. I saw no discussion on distance between supports. What is the general consensus on support materials that are readily available from Lowe's or Home Depot? How far apart should I plan on making the supports? I will be using 14awg insulated copper wire.

Thanks!
