provide a sun shield might seriously affect the rf coupling mechanism. The
Chevrolet Tahoe uses a metalized material in making their ‘privacy’
tinted glass for the side windows. It tells you in the owners manual you
cannot put a ‘through the glass’ antenna on the windows. I suspect
they use the same material in the sun roofs to cut the sun intensity down.<o:p></o:p></span></font></p>

fix with the sunroof retracted. Then slide the sunroof closed and see what
happens to your GPS signal. That would tell you if you had a metalized
material being used to provide the window tinting.<o:p></o:p></span></font></p>

capacitive antenna to a sunroof, i.e., a horizontal versus vertical mounting of
such an antenna. It seems to me that it should be workable if the fastening can
withstand the effectsw of weather and direct wind effectg. Thanks for any
comments on this idea, 73 de Rod,VE1BSK.</span></font><o:p></o:p></p>
