Same here. I've been using Larsen antennas personally for nearly 30 years, and using them at work for close to 20. I've never had one fail, neither the old ones or the new ones.
I have a nearly 30 year old NMO-27, never had an issue with it, tuned nice and flat (<1.3:1) across the band.
Using a lot of 1/4 wave antennas on VHF and 800MHz at work, no issues.
I have a < 1 year old wide band 1/4 wave on my work truck, as well as a < 1 year old 3dB 800MHz antenna. I've beaten those off road on tree branches, overgrown access roads and low parking garages, no issues.
I have the same wide band 1/4 wave on my personal truck. I went through a parking garage in Las Vegas a month ago and forgot about it. Tall truck, low garage. The spring took a permanent cant back a few degrees but worked just fine. I ordered a replacement spring and swapped it out.
I've talked with the Larsen guys at trade shows, knowledgeable and stand behind their products. Considering the number of them out there in public safety and commercial use, they wouldn't be around if there were issues, even with the newer stuff.
I'd not put my trust in a hobby/amateur grade antenna. Get the commercial grade stuff, it rarely costs more than the hammy stuff.
