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.

could aim on side lobes all day without consequence.

Maybe I'm crazy, but a 10db antenna will still give 10db if it's
aimed at a sidelobe won't it?

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 a dish?
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?
