Due to a double-ordering snafu with Amazon vendors I'm left with a brand new sealed-in-the-bag NMO mount, with attached coax, Laird SNS-1-40422. It mounts into a 3/4 inch hole. That hole could be in your car roof (like mine!) or a bracket or your RV roof. It's commercial grade. It came to me for $17.23. It can come to you for $15.
