Yep, they were designed to be TV antenna towers.
Besides the aforementioned PITA to climb or work on (I refer to
them as meat grinders - your feet take a real beating even with real live
leather climbing boots), the X diagonals don't even meet which takes away lots
of torsional resistance and the spaces between diagonals are a common
failure point. Also, they are held together with aluminum rivets - not the
best
material for that.
Another problem is that the twisting of the tower due to ham type
tribander loads tends to crack the rotator shelves which are just sheet
metal.
Be aware of their limitations and they'll work okay.
