I can only echo Jim's statements! A couple of weeks ago, my much older
HDX-572 re-nested in the same manner, except I was in the house, so don't
know exactly why. My 4 element quad survived well (surprisingly!), the the
tower is toast, with many bent and torn pieces. It is a real shame that US
Towers won't provide cable stringing information, as I would have re-strung
mine before putting it in operation a couple of years ago. It is being
replaced with some AB-105 fixed tower, so I won't have to face this again!
73, and good luck, Jim!
