My thoughts is the nuts, lock washers and larger ends are brass. Would the be worth having them checked?

Grab a magnet. If it sticks it’s gold. If not brass.

I’m guessing gold here these being antennas. But I don’t know for sure. I’ve definitely found gold plated washers and nuts in high end CB equipment… so there’s a chance.

I’m with Lost on this as well.

Worked with those SMA connectors for some time. Forget what the one smaller, push/pull connector is called. Almost always, in my career anyway, gold plate as well. Yes, the nuts and locks too.

However, just because they’re not magnetic, does not mean they’re entirely made of brass. I have drawers of these and I can tell you, they’re not all attracted to a magnet and they are thinly covered in gold. The metal underneath appears to be a white brass.

Hit it with a file to check. Some of those from WiFi are indeed all brass.

They do stick to a hard drive magnet.
Since they stick I am guessing gold plated nickel?

Less likely in this context. More likely an irony bronze.
