I have a 2009 Ford Escape. I am currently using a glass-mounted scanner antenna and it is decent for local stuff, but I would like to pick up more. I am not into drilling (sorry). Can anyone recommend a good mag mount antenna for me? Thanks in advance.
If possible, include links to the retailers that sell them.
Understood, but if you ever decide to drill, I wrote up a full description of it over on the BatLabs.com forums. Not hard to do, even with a sun roof.
Narrowing down the frequencies you want to listen to would help, but here's some ideas:
For a magnet mount base, look here:

Pick one with the connector you need on the end to match your radio. While an adapter doesn't really introduce enough loss to make a big difference, they do add additional strain to the weak antenna jacks on most scanners.
I really personally favor Larsen brand gear. Been using it for 25+ years without a failure, some of the stuff still going strong for over 2 decades.
As for the antennas:
Picking just the frequencies you need to listen to will usually give you better performance. A single band antenna will outperform a multiband antenna if you just need to listen to one band.
These guys get consistently good reviews:

Those are low profile enough and flexible enough that they'll clear most parking garages.
My wife's 2009 Escape has a VHF 1/4 wave on the roof, so about 18 inches tall. It does just tap the garage door when she pulls in, but after hundreds if not thousands of times it's never been an issue. I certainly wouldn't want something any taller, unless you really didn't mind removing the antenna all the time.
Only issue I can see for you will be getting the coax inside the vehicle without it getting damaged. I'm not personally a big fan of magnetic mount antennas, but I understand those that need them. I think you'll want to keep a close eye on it over time to make sure the coax doesn't get damaged. That alone is usually enough to convince/remind me why I do permanent mounts on all my installs. I won't deny, however, that I do have a mag mount that I use for testing.
