The XR5 is certified with a 31.4 dbi antenna. Nothing in the FCC
certification says what type of antenna. Someone I spoke with
familiar with the certification process said the type doesn't matter,
only maximum (perhaps minimum too, I can't remember) gains.
Actually it appears to have been tested with the following two antennas:*
*Hyperlinktech, Dipole, HG2403RD-RSF, 3dbi
Radio waves, Parabolic, SP1.5(2/3)-5.8, 31.4dBi.
The ceritificate at the FCC is for 5.7 only. Not sure what happened to
the 2.4 grant.
So it looks like you can use the XR5 in 5.7 with the radiowaves
antenna. However, any other antennas would be illegal until such time
as Ubiquiti specifies in writing that the additional antennas are legal
to use, with specific model numbers. I would, however, be skeptical of
anything but a Parabolic of some sort, since the FCC requires the
certification testing be done for each antenna "type" - where type is
not neccessarily just "parabolic", but things like "parabolic with
dipole feed, DC open, and a specific in and out of band gain pattern".
I would expect there to be no problem with Ubiquiti saying that the
lower gain radiowaves 5.8ghz parabolic antennas are ok, but anything
else may require additional testing.
