In this case though we're only holding a light Aluminum structure 
vertical. In these cases I use only enough pressure to do so after the 
"stretch" is out of the nylon as it really doesn't matter if the antenna 
moves a little.  Pulling nylon "tight" is like tightening a guitar 
string.  OTOH I've been up several hundred feet on a commercial tower on 
a really windy day. Those big guy lines were singing quite loudly is a 
rough musical note.
