Broken nmo?

[SirJ]

😂 before I started this afternoon project, I thought about it for months, mainly because this is a $60k truck. As I was tightening the top portion of the Nmo I slipped off the two very large part of the nmo (do they make a tool?) and the pliers knocked this disk off the center of the nmo. There is a copper center piece sticking out that I assume is soldered in but I don’t see any! Even with a microscope. So I took a very small foil ball I made and sandwiched inbetween the disk and delrin and screwed the antenna on lol is there a easy way to fix this without having to remove the nmo and the silicone I used inside to seal it shut ?

The second picture is the type of FME nmo I am using, I like this because of a 3/8 hole only need to be made which means more surface area to grab when sandwiched also the coax with fme can be removed easy for install.

That's the center pin contact pad you knocked off. I would replace the entire thing, others might tell you they solder them back on.

As for the tooling, there are many options. I've always used the flat spanner wrench style and a thin profile adjustable wrench.

What brand/model mount is that? If it is a Larsen NMO-HF type, you might be able to source a new center. If it's not, just replace it, as a417 said, it's not worth a sketchy repair that may fail.

Also, if you are installing it correctly, the silicone underneath isn't necessary. Won't hurt, but not necessary.

Congratulations on finally doing the permanent install. I know the first one is hard, but it really does pay off in the long run.
