Hey everyone, I am scratching my head over here. This is our first licensed link deployment and we're having some issues.
We installed a 13 mile, 6ghz link made up of two 820s 2+0's with 3' radiowave dishes and the PCN shows the signal should be -39, but the best we can get is -68 after re-aligning both sides multiple times.
Today on one side I took the ODU's off of the OTC(combiner) and checked to make sure the waveguide(little disc) on the ODU was set properly. One of the ODU's has the v set in the 12 oclock noon position and the other ODU has the h set to the 12 o clock position. I am guessing this is how it should be with the 2+0 configuration as well.
We also changed the circular mount on the back of the radiowave dish in order for the OTC to fit on there properly - it all came with the cambium link planner kit.
The instructions refer to rotating the OTC on the back of the dish to get maximum cross polarization difference. We tried rotating the OTC with the two ODU's on it left, right, center and all variations in between on both sides and yes the signal changes, but not for the better on both sides at the same time.
We really don't know what to do. We have the vertical ODU set to vertical on the combiner, same with the horizontal, but this just doesn't make sense.
Does anyone have any experience with the 2+0 set up and maybe you can help me out a little? We have 2 links and can't finish the first yet - we haven't started on the second and don't want to until we figure out the solution to this first pair.
I have attached random pics outlining our setup.
