Review on AntennaMastsRus - Made In USA - 4 Inch Gold Aluminum Antenna Is Compatible With BMW K 1600 B (2018-2019) by Gary Zielinski

Love the look and the finish is great. On the other hand, the performance is minimal as my radio seems to work the same as without the antenna. I don't really care as the bike radio sucks with all the noise and wind and earplugs (which you should wear). I don't use the radio very often, except when I'm bored and hanging around.
