Thanks, but I don’t see the answer to my question there. That page has a metric for unobstructed line of sight, but I was asking specifically about vertical coverage differences between the AP One and the Rugged.
The radiation patterns @Alan posted back in January show distinctly different vertical coverage patterns for the AP One and the Rugged, listed as Dual-Band Wi-Fi Antenna on that page:

My current inference is that the Rugged’s vertical radiation pattern has many distict lobes with dead spots and is far less likely to give decent coverage vertically than the AP One. I was asking for confirmation of that inference.
Thanks.
