Hey Sotto! Thanks for bringing that extra cool value to our attention. Why don't you get your self a Cushcraft Ringo Ranger AR2 antenna up on the roof and see how it works out. I hear they're nearly bulletproof in salty, foggy SoCal air. That and the radio will only set you back about $150.
(Sorry, I talk to myself all the time. May as well do it here, too.) ;-)
