Remember the schtick they did where Gilligan's fillings were pulling in a Hawaiian radio station?
Well, the other day I had just finished running cat5 to a repurposed space.
I grabbed my tone probe, and as I was walking back from that room to the server room to tone the cable, I flicked it on and aimed it at the conduit to make it squeal and verify the battery hadn't died.
I was surprised to hear a local radio station coming in loud and clear.
Wandering the building, it turns out that every conduit in the place is acting as a wave guide.
Anyone else run into this?
I'm not seeing any degradation - my validation tests still pass at gig speed.
I'm wondering if I should make an effort to ground the conduit - I'm not using STP.
