Possibly. Dishes have one really sharp focal point.
Panels just need to get as much of the area in phase as possible.
You can move them off boresight and actually get more signal in a
multipath situation than a reflector can.

Integrated wouldn't pick up that much better if it was NLOS.

My point is, at 0.6 miles if he was on main lobe he would have
a -40 something. Being on a sidelobe gets him the -67.
Shouldn't the dish still add 10 more db?
....unless we're interpreting this as meaning a side lobe of
the dish. That's possible, but at .6 miles the installer
would have to be drunk.

Otherwise you could aim on side lobes all day without
consequence.

That was one thing that I was thinking about as well.
If I got my azimuth correct and the guys on the tower
got the antenna aligned correctly they should be on
the outside of the main lobe but we've got two LOS
customers at .75 and .4 miles that have signals in
the -50's. I expected them to be in the -30's or
-40's.

for best results, try to adjust your antenna tilt
on the AP.
(Have someone look at the CPE's (paying attention
to the farthest ones), and then adjust the tilt
on the AP Antenna... so as to best combination of
signals on the close by cpe's and the far cpe..)

Subject: [AFMUG] Can you be too close to use

I upgraded a customer to 2.4 ePMP last week
that was about .6 miles from
the tower. The signal with just an
integrated SM was -67 so I decided
to use one of Chuck's dishes for ePMP but
only got an extra 2 to 3 db
improvement. The last time (only time) I
used the dish I got 8 to 10
db improvement but was about 2 miles from the
tower. Is that too close
to the tower for a dish or is that just the
nature of wireless?
