I think that it is easier and less confusing to say “An unguyed tower than can be guyed”

What I mean with "a guyed tower that can be unguyed" is that the guy wire just adds strength to an already strong structure. A self-supporting tower can stand with no other support. That's the case with my tower. By adding guy wires you add, in this case, more strength to the tower so it can sustain more wind.  If there is no, or just little wind I can remove the guy wires without the tower tipping over. So, "
a guyed tower that can be unguyed" is a self-supporting tower that has been equipped with guy wires.

I hope this is not too confusing,

    I don't have a problem with guying a self-supporting tower IF the guys have very little tension on them (less than 40 or so pounds). Tower strength comes from the legs - the more tension you put on the guy wires, the more compression you put on the legs thus decreasing the capacity of the legs to support the tower. With a small amount of tension, you're not trying to hold up the tower - just restrain it from wind forces. With little or no tension, you could be subject to wind slamming - a violent and potentially fatal condition.

    What is a guyed tower that can be unguyed per your comments above? I'm not sure what that means.

>  I don't know where this misnomer comes from that a self-supported should be weaker if you added guy wires. Maybe somebody can tell me. I understand if the guy wires have a very steep angle the load on the tower will increase but that is not the case with mine.
    It's not weaker - it just has potentially less capacity.
