Could be he was taking into account the curved surface radii would actually provide a longer transition path inside plastic medium for the arriving wavefront to propagate through, if part of the Horn aperture was in the curve & part wasn't. Then there would be a phase shift induced to one side of wavefront, resulting perturbations within the Horn would cause antenna gain loss.Don’t know why you included curved surfaces. As long as they are RF transparent and the antenna can be mount facing parallel with the road, curves don’t matter.
It's the same reason one should never put Remote antennas behind plastic (or metal) mesh grills.
