I suppose if you're planning a macro TD-LTE network, all of your cells
are the same size and evenly spread out. That never works out IRL for a
WISP. Beam steering is where we need to go, but a WISP can't afford
eleventy brazillion dollars per site.
The Cambium/Laird "90" degree sectors have null-full and seem to work
very well for nearly every scenario with the 3.6 450. 60 to 240 feet
high on sites with SMs as close as 1/4 of a mile. We do have some
customers a hundred or two feet away (like an elevator office) and they
do end up seeing the back side of the opposite sector a bit, but so far
it hasn't been much of an issue. Just today we put a customer about 15
degrees from the "edge" of a "90" and there was still plenty signal
there. The pattern does get kinda skewed and lumpy out that far though,
and you can see that in the beamwidth plot. Good enough until we add
another sector and turn things a bit.

But 4 degrees downtilt on a sector with 7 degree vertical beamwidth
seems excessive unless you’re doing really small cells.

Alpha Wireless makes a great sector. Alpha is the antenna OEM for
Telrad and Airspan among others.

KP makes one - I haven't used them myself, but I've always only ever
heard good things about their antennas. I can't think of any others in
120 degree off hand.
