Tony, To answer your questions:
1)?Am I correct that the GRP reflectivity can add to the signal strength??If so, by what amount is typical? Yes, it will add roughly 6dB depending on interested frequency, etc. 2)?How can I prove to my client that this is so? 3)?What documentation exists that explains this? Search IEEE EMC Symposium records, I remember there were some discussions about it years ago, probably 1996 or 1997 Symposium??? either Austin or Denver, can't recall.... 4)?Or is my client correct and I have some unexplained problem? Pls remember the declared antenna gain could be antenna manufacturer's declaration which may be the standalone performance of the antenna thus may not consider the customized application of the equipment you are testing. Any installation may change the antenna pattern and affect the effective gain, either way is possible. That's why product manufacturers shall make antenna pattern analysis based on its customized installation, rather than purely relying on the antenna manufacturer's declaration of the antenna performance.
