Antenna pucks? What are and what are their use?

[CrashRecovery]

So in my search for knowledge on antennas it has been brought up to try a setup using a NMO Puck from breedlove. I'm still unsure what they are there for. I can understand if they are used to prevent damage to the roof from a standard NMO connection.
It was suggested I use a puck and a Larsen NMO style antenna. So what do I gain from using a puck?

I beleive the main gain is the best possible grounding contact you can get. The drawback is to achieve this you must drill a hole in your car/truck, pull the headliner and do a little welding. If you still owe on your car/truck you might not want to go that route. The resale price may also be affected by having a hole drilled in it, another angle to think about before pucking. If you want to run power it's really the best mounting option i think.

Welding? Puck mounts bolt on, no welding

I haven't found anyone’s who has had a problem at sale. If it’s a worry, install a cell phone mount and cheap antenna. My father Buick’s and Cadillacs going back to 1962 had baseload for radiotelephone on rear fender top at rear glass corner.

Haven’t seen welding. The puck type features thru-bolts.

Maybe someone can link the Breedlove video on how to install.

Puck mounts also provide a thicker base over a wider surface to reduce flex that you'd get from sheet metal at higher wind loads. I remember a thread of people using saw blades on the inside of their roof to add stability and reduce flex.

Just remember when you buy a chassis punch, don't buy one for 3/4 pipe, make sure it's to make a 3/4 hole because there's a difference. Or else you'll end up with an oversized hole you can't do anything with. A radio chassis punch is what I've got (pictured)

I used a metal hole saw in a drill, makes a clean hole in literally 20 seconds

Several vintage 730 on eBay.
