The bracket doesn’t amount to much and is available used, often. Here’s the rohn for 25G: http://www.dxengineering.com/parts/roh-hb25ag?seid=dxese1&gclid=CKyxgL7Sw8wCFYpZhgodY78AoQ The material is of modest size, about 1”X5/16” strap, easily fabbed. I use a 2X6 to bridge several studs. And reinforce the stud connections top and bottom. WL
