The overall length according to google is 123 inches. As being an amateur radio operator along with running a cb radio, yes you will hit trees, and bridges. I run a stainless steel 102" whip for my cb which is mounted on a chevy cobalt. I hit everything unless it's tied down with the whip clip. Also if you do forget to tie it down and hit a bridge that has open steel on the underside, don't key up. I did that once and fried my cb since I was running an amp at the time.
