[AFMUG] That ain't right, part 2

[George Skorup (Cyber Broadcasting) via Af]

I lost the original thread for some reason. Anyway... we encountered the 
same problem with a different radio. Was a KP reflector, but we used a 
connectorized SM on a 2' Laird HD dish as a replacement since the link 
needed some more power anyway. Got it up, started final alignment and 
bam! like a lightswitch, H pol power level dropped to -89, V SNR low, H 
SNR higher just like before. Changed elevation a little bit and it came 
back to normal. I had the guys move elevation again just so I could 
believe what I was seeing. Somehow we have a reflection that is now 
apparently just outside of the beamwidth of the 2' dish. Hopefully. At 
least that's my theory. It's up 160' on a grain leg about 4 miles to the 
main site. I wonder if the reflection point is the tops of the trees at 
some mid point. Maybe MIMO-A will help if this starts happening again.

Here's the new SM link status. It's been stable since. Really strange 
how the multipath was swinging back and forth on the reflector. I guess 
you get to learn/hate RF more and more every day.
