    dear friend
    i am specialized in design of steel antenna tower
    i dont think sap is suitable for this kind of structures.
    because you need first to determine the wind load on structure according to eia/tia specification,then determine the wind load on dishes and other ancillaries,
    in my opinion the best softwares for these structures are:
    mstower---risa tower---tower---staad x tower v8i
    dont forget to read carfully the eia/tia speciffications

    dear friend

    first of all if you use sap you will have to put the effective length of each member in the tower.this is a complicated job because each member (leg,diagonal,horizontal,or bracing ) has its factor according to eia/tia specifications.
    i suggest that you use ms tower or risa tower,thus the programe will put the k value for each member and calculate the slendeness ratio in order to find the allowable stresses.
    meanwhile the programme calculculates the force on the dishes and ancillaries.for all load cases related to wind loads in all directions ,then check all members according to required specifications(asd,bs8100,asce,or other
    you may check the bolted joints as well.
    i hope this information will be helpfull for you

    dear friend
    sap can not design comunication tower,because you nead to put the k values for each member manualy acoording to eia/tia specifications which is not included in sap library.
    also sap has not library for dishes,cables,platformes.
    the programmes that can do this job perfefctly are
    ms tower,pls tower,risa tower
    i found that mstower is better than the others.
