Chateau Pro ax Antenna Pattern

What is the radiation pattern for the antennas used on the Chateau Pro ax? Is there something different about the flat sides vs the narrow sides?

I looked up similar antennas with posted patterns and it appears they do about ~50 degree vertical and 360 degree horizontal. Is this true for these?

The Chateau Pro Ax has been FCC tested, sometimes (not always) information can be derived from test results:

Loosely, the device should have omnidirectional antennas (so 360° in the horizontal plane) emissions should have the shape of a doughnut (toroid), the higher the gain of the antenna the skinnier is the toroid, the lower the gain the chunkier it is, see:

Since the antennas are relatively low gain the doughnut should be rather thick, so the 50 degrees you mention seen possible

Thank you. I appreciate the information.
