Kinda. I ride in Seattle. I’ve had dropouts with my previous remote. I used the feather remote. I had carbon fiber skinned on both the top and bottom of my deck and I had a CF skinned enclosure. However pulling the antenna outta the receiver fixed that.
Even though taking the antenna out twisted it , taking it out was a better improvement than the bad effects of twisting the antenna. So interference of layers > interference of twisted antenna based upon my experience
