Nobody at Peplink seemed to notice my post, or comment on it. It seems Peplink has no solution for mounting its antennas to a roof rack. I went with a different antenna, from a different vendor. I am using the roof rack mount from SpaceX/Starlink for my Starlink Mini. I’m using a Parsec 11 in 1 antenna with magmount to the roof of the van, not attached to the roof rack. It’s too bad. I’d have used a Peplink product if they had any interest in selling something that’d work for me, and for you.
