We have the Alpha AW3089 in use right now.
The most obvious difference with KPP is the electrical downtilt of 2
degrees, vs 4 degrees on the Alpha. In theory you'd get more distance
out of the KP, but the Alpha might be more deaf to distant noise.
The KPP spec sheet showed deeper nulls than the AW3089, but according to
KPP that's because they're showing an average gain across all of 3.5ghz
to 3.8ghz. They sent me an image showing the pattern centered around
3.65ghz and it was pretty damn similar to the Alpha.
Yeah 11dbi isn't much, and yeah the nulls are a real bummer. We're using
them with the Telrad Compact which has quad antenna ports, so we're
using two omni's and rotating one of them 22 degrees relative to the
other so the nulls of one antenna should be sitting on the peaks of the
other.
....and by the way, KPP told me that 0 degree on the antenna pattern
corresponds to a line drawn across the two N connectors. Maybe you'll
get lucky and your 6 customers could all be placed on a peak.
Does anyone know if the KPP dual slant omni is an Alpha AW3089 or a
knockoff? And has anyone used either of them?
My experience with 5 GHz dual pol omnis has been disappointing, I'm
wondering if these bigger, more expensive omnis deliver better
performance.
11 dBi isn't much if you can lose 3-5 dB at certain azimuths, another
few dB depending on frequency, and another 3 dB at zero elevation due
to 4 degrees electrical downtilt with an 8 degree beamwidth.
For $600+ and 6 inches diameter, I'd expect it to wash and wax my car.
