He said that it can not be more than 24" high, otherwise it needs to be back guyed.

Somthing like in my area we are required all the mast over MM have to be backguyed keep in your mind there are pretty good percentage of area where ice will encounter here and yeah we do get it from time to time. Also the height of mast can make the diffrence of drop of span some case I have to use much higher mast to clear the area if the sisuation called for.
