The wire mapped out all OK? No shorts? I would think if degraded by water or even a lightning strike wouldn't there be a short in the cable?

You mention its approx a 100' run but the tester is showing 215'. This is making me think short if it truly is closer to a 100' run.

Are you sure you are reading that speed test right. Why would 10G be cat3 speed? Unless its 10mbps and not 10G.

No. Degraded by water or lighting strike will NOT show up as a short a lot of times.
You are dealing with a signal. A signal that has bandwidth. Testing for a short or open circuit is only good for a DC (or close to DC) circuits. Catastrophic failure if you will.
If you take 100 feet of lamp cord and run 4 pair of it, it will test fine for shorts or opens. However you are not going to run a 10G network over it.

Which runs us into HDBaseT speeds. You are dealing with a 10G network connection there. It is truly amazing that the manufactures have got these devices to work over cat5e, the distances that they do. But we all know how finicky the connections are, because we are pushing the bandwidth so hard.
A meter to test 10G speeds properly, cost thousands of dollars. And with 4K HDR @ 18Gbit/s now, I don't even know what testers can fully certify that.

But with a simple meter like Tom's, testing out to Cat6 standards, can still tell us a lot. In this case, the meter couldn't do maximum bandwidth that it can do over this cable. Which means there is a problem with the cable, as it will need to max out his meter as a minimum in order for his HDBaseT extender to function properly. "If accurate", his meter has severed him well.
If the meter had shown it could pass its maximum bandwidth on this cable, then there could have still been an issue. As the cable might not be able to pass that highest bandwidth only, something his meter wouldn't be able to test for. Requiring a much more expensive meter to test with.

But the simple solution most of us do - run a new cable temporarily across the ground and see if it works. If it works on the temporary cable but not the one in the ground, Bingo! No expensive tester needed.
