There is an antenna in the back glass. Reception is shaky at best.
To switch out for weight saving on the antenna seems ludicrous, but add that up to 100 extra things and you've just lost 100 lbs. Think it's impossible? try about three hundred lb loss without losing any comfort. Well, maybe a little more road noise - exact same noise level as the type R. I would type up a list of all the give and takes. But over the past three years, I don't think I have the time to list them all! This just gave me an Idea of a new topic.... What have other members done to save weight?!
