So the arrestor you linked before?
The other thing one can test is if the arrestor presents as a short at DC, there’s a class of these for Radio/CB type applications where they pass RF, but look like a short to ground otherwise. These would be unsuitable for GPS/GNSS applications which provide a DC bias to power the active antenna.
I’d expect these could be check with a basic multi-meter. ie is it low resistance/short, can you measure ~3V at the far end of the cable, etc.
But I think it would be helpful to compile a list/gallery of part# and pictures of ones found on assort eStores that are suitable vs not. Or one or two that SparkFun themselves can stock.
In GPS/GNSS receivers the inductor used for the RF/AC block for the DC bias is typically the device that acts as a sacrificial fuse
