The Outbacker was originally marketed as a mobile antenna that would
survive a beating in the Outback of Australia. It is not a particularly
good peformer as an antenna (they normally test somewhere below a hustler),
but they will survive and function. Adding a spring will only cause you
tuning problems...

I am mounting an Outbacker on the rear hatch (side) of my Grand
Cherokee using the Diamond K400 trunk lip mount. I have a Hustler
spring I was going to us on it, but wonder what opinions are about how
necessary that is?
