Being a ham radio operator, I use an antenna that employs capacitive coupling to pass radio energy through the glass to the antenna -- doing that 25 years now. I moved the antenna from my 1983 850 to my 1999 S70, and antenna performance is way down on a nearly identical installation with the S70. Question: does the rear window of the 1999 S70 have anything in the glass laminations that is metalic -- perhaps an oxide -- to reduce glare or ultraviolet. If so, and I hear that it is sometimes done to reduced IR and UV light and heat, it would really mess up my ability to pass radio frequency energy through the glass. Any good wisdom on that? Thanks from Tedster; reply on the brickboard or to w3tb@comcast.net.
