We want to put a bend right in the middle of the RRH section between points S and B. Does the rule B18.104.22.168, saying that bent members may not extend longer 28 in between named points, allow supporting members to be added?
I have a bend in the SIM, and the distance between Point S and Point D is greater than 28". What support is required?
a) For bent tubes longer than 28in. AND a bend less than 30deg, a single secondary member must extend from the bend to a Named Point.
b) For bent tubes longer than 28in. AND a bend greater than 30deg, two secondary members must extend from the bend to two Named Points.
- a bent SIM of less than 30 degrees may be supported by Point Q on the LFS
- a bent RRH may be supported by Points A, C or R
- a bent LFS may be supported by Points D, S or Q
