Hello what do you recommend for a good mobile magnet antenna
I have owned many K40 antennas. I have owned several Wilson 1000 magnetic antennas.
However, the game-changer was the Tram 3500 with a 5-inch magnetic base and rubber boot.
I have all sorts of smack from folks who disagree with me.
The rubber boot on this antenna works!! It
DOES NOT scratch the paint, based on my experiences.
I have photographs of the trunk and roof of my Toyota.
I also use the Tram NMO monitor antenna with the same size of magnet and boot. I make sure I buy the 58U, not 58AU coax. I top this with a Larsen Tri-band monitor antenna.

PS: I was nearing a prison unit in Texas with the K40 on top. This was near Rosharon, Texas. There was a nearby tornado that hit the pig sty of the unit. I don't know if straight winds were responsible or other wind types, but the damn wind blew it off.
The K40 was very hard to remove due to the magnet strength. The recommended antenna is just as strong, but much easier to remove.
One odd thing happened when I was using my Classic Cobra 25. At the time, I was using a Passport Max II, unshielded. When I keyed the microphone, it would set off the laser alert. I asked a radio technician why and he told me it was likely a ground issue. So, I attached the mounting screw to the body of the car, problem solved.
Now, I am using an Anytone 500-M. I am now using a Passport Max 360 (not C) with proper shielding.
About two weeks ago, the Max 360 succumbed to the Texas heat. It took a hard fall. Now, there are some false signals. I am pretty certain the fall affected the shielding. Soon, I will be sending the radar detector back to Cedar for repair.
