I think you just answered a question I have, but I'll follow up to make sure: I'm going to set up a temporary base station in my garage using a mobile unit and a magnet mount antenna. My plan is to place the antenna on the top of a steel tool drawer cabinet that's about 2'x2'. The cabinet top has a thin (~1/16") rubber mat on top. Based on the quote above it sounds like I don't need to remove that mat before placing the magnet base on the cabinet. Correct? Thanks!
