[TowerTalk] help with rohn 25g bracket mount

[k2vi]

Im going to errect a 38' rohn tower next to my house. The house is brick exterior. Should i drill straight through the brick into the attic then put a 2x6 across or just used 6 anchors made for brick that expand and just lock em in with 3/8 all thread. the bracket will be 15' above ground. The base is not going to be a tilt over so it will be solidly cemented in the ground with a 3' base section. What method should i use. Would apreciate any replies. thanks guys.
