I have an old cellular phone adhesive back glass mount antenna.I am trying to figure out a way to effectively use my handheld scanner in a classic Ferrari Testarossa. I mostly want to monitor Alabama Highway Patrol frequencies (Troop G and F). I would really prefer not to do any permanent mounting, drilling holes etc. Even a magnetic mount would be undesirable because they tend to damage paint, plus wiring it would be difficult.
I have seen a few window mount antennas, such as pictured, are there any good at all?
The one I have picks up the 700-900 bands fine.
