Canopy troubleshooting logic puzzle

[Bill_G]

Okay puzzle fans - test your logic.

The Canopy / Cambium PTP (point to point) microwave features dual polarized signal paths - vertical and horizontal. Typically you use a dual polarized dish, though you can use two individual antennas. Your link is having problems, and the diagnostics screen shows 100% vertical signal, and no horizontal at both the near and far ends. You swap the RF cables at the near end so that the Canopy V port goes to the dish H, and the Canopy H port goes to the dish V port. The near end diagnostics remain the same - 100% vertical, and no horizontal. The far end diagnostics have inverted - now it's 100% horizontal, and no vertical.

Which end is broken?

Picture goodness to add emphasis why you need the correct answer.

What happened to the dome heaters on the microwave dishes? Looks like none of them are working.

That's money most agencies don't have. And a dome heater wouldn't have helped the ODU or twin cables that have turned into a popsicle. The hoar ice builds up quick at some of our sites.

Answer - The near end horizontal xmitter has failed. Replace the near end ODU.

And thankfully, in this case, the far end is the picture and the the near end is well below the snow line, not a popsicle, and easy to replace. However, the top of the tower was twisted by high winds. That's a problem for another day.
