At minimum, tie the guy wire around the cross members and the leg. The most
common problem is that the leg can be ripped off the cross member (which really
weakens the tower).
In my case I have a large plate that is tied to the legs. That is to eliminate
the forces on the welding between the cross member and tower leg.

Remember that guys should attach to a bracket or saddle that fits around
the tower, not tied around each leg. If there are none made for the
particular tower then we should have the required brackets fabricated.
It will really be doing the tower a favor as it removes *all* lateral
force exerted by the guys on the tower let alone individual legs and
leaves only the vertical component. Remember when the wind is blowing
the upwind leg us the only thing resisting all that lateral force when
the guys are fastened to the tower legs instead of using a properly
designed and installed bracket.
Yes I know many of us, including me, have gotten away with fastening
guys to tower legs, but no more at least for me once I did the
calculations as to how much force the upwind leg has to withstand in
addition to the force exerted by the guys. It only takes a little trig
to come up with some scary figures.
