get an S2000 if you don't care too much about radio
what does the S2000 have to do with your radio?
do you think that it affects reception or something?
I guess my car must be really special - because I pickup a station on each and every channel... heck, I even pickup college radio stations while being 100+ away from them.
ie; I'm in San Diego, but can still listen to Santa Monica college radio... or while being in Los Angeles or Valencia and the surrounding areas, I still pickup stations broadcasting from San Diego and polka stuff from the Mexican boarders.
A little FYI - your antenna already travels at least 14 foot before it even gets to the rear of your car
removing 2 foot of antenna by replacing the stock with the S2000 really hasn't been proven to make a noticeable difference
