it’s a magnet mount, I have 2 whips made from old GM radio antennas that I cut to lengths for 150Mhz and 800Mhz that I can swap between depending on what I am listening to.
I find the speaker in the scanner works great, it’s loud enough. I user an ear piece when driving with the wife and kids so they don’t have to hear it. The ear piece wire runs around the window frame to the back of the seat so it does not get tangled.
