Has anyone else noticed any issues with = their WAAS=20 GPS installation?

I just convereted a 530 and 430 to 530W = and=20 430W. My GPS antennas are on a tray just under the = glass=20 section in front of the vertical stab on my IVP. Since I got Waas = I get=20 "No GPS navigation - user other nav" message. It happens on the = ground, it=20 happens whether near buildings or not, it happens to both navs but at = different=20 times. It lasts from 30-45 seconds typically.

One theory that has been put forth is = that the WAAS=20 units look further down the horizon (or need to to get a big enough=20 constellation) and that I may have some blockage at those low=20 angles. So far I haven't seen this happen in the = air.

I also converted my cessna 530 to=20 530W. I haven't noticed any issues. The antenna = is=20 OUTDOORS in that installation.
