It is the horizon 150Mbps.

You can bang the physical dish up pretty good and not need to worry.
The feedhorn is the most critical unit. Which Dragonwave radio are
you using?

15-20db off typically means cross polarization. Have you double
and triple
checked they are both on the same polarity?

I have a Dragonwave link that was performing about 35-40db lower
than the
link budget says it should. I sent tower climbers up to repeak the
link and
found they did have it on aligned on a horizontal side lobe.
After re-peaking it got better, but is now about 15-20db lower
than the link
budget. It is running about a -52 and the budget calls for a -34.
They did peak the vertical axis, but is it possible that even
though both
antennas were mounted plum, that they are aligned on a vertical
side lobe.
Like I said, they did say they peaked the vertical, but I don't
know if they
did a proper sweep on the vertical because it is not a quick to do
as on the
horizontal. They are both plum, but the antennas have about 300ft of
vertical separation at 5 miles. Would difference in height put
them in into
a vertical side lobe? I am asking because the 30in antenna's had come
slightly damaged, but it appeared to just be where the raydom
attached to
the dish. Dragonwave did not think this would cause an issue. I
just need
to know if I need to pay for 2 more tower climbs to re-peak the
vertical, or
take down the dishes to return them. Thank you in advance for any
advice
that can be given here. By the way, it is our first licensed link,
so it is
my first experience with anything above 5ghz.
