... An especially large motorcade ferried President Donald Trump around Beijing during his trip to meet with Chinese leader Xi Jinping this week. However, a pair of heavily-laden Chinese SUVs with huge custom roofs, a configuration that does not appear to have been previously seen, were of particular interest. The motorcade also featured several other vehicles with interesting, but far less substantial additions to their roofs.

The unusual SUVs were first spotted as Trump's motorcade moved through the Chinese capital on May 13, as can be seen in the video in the social media post immediately below. They continued to be a feature of the motorcade throughout the U.S. President's state visit, which wrapped up today.

@#3 ... Some sort of AA defense thing? ...

Not sure what you mean by "AA."

That aside, the vehicle certainly seems to be odd.

I'd like to know what are the materials used for that ~addition~ to the SUV, and how that material may affect or not affect radio frequencies.
