[Elecraft] A Screwdriver Mobil antenna for my K2?

[k7hbg at dslextreme.com]

Hi everybody!
 I was thinking of running my K2 mobile and of course the first thing I
thought about was an antenna. The High Sierra "Sidekick" has gotten good
reviews on eham and an electrically driven screw driver antenna does have
a certain appeal. The small size and a trunk lid mount would be great for
my little Honda Civic.
 Has anyone had experience with the K2 and Sidekick antenna combo? Is
tuning a problem?
