Hi Basillus,
The link works for me. Thank you for sharing. I will probably get one of these later. Please be aware that when using a directional antenna on the 902ac a change of a few degrees can change the signal up to 10 dB, or make the orientation such that the antenna becomes sensitive to room activity. For example, if someone walks through the room, you might get a change in signal reflections and this can impact the retries big time. It is exactly for this reason I’m using my daughter’s old Lego, so I can build the base where I can change the angle of the Aruba as well as of the directional antenna to get the most stable signal between the two. I tried wall mounting, but I always get better results when the Aruba is not parallel to walls. Keep in mind that Aruba has the strongest signal at 30 degrees down from horizontal and my test proved this angle does work the best….in my case it is tilted around 30 degrees down and around 3 to 5 degrees in the horizontal plane. For me, setting up the directional antenna and getting good results was a very long and a frustrating process. I never tried it, but getting an omnidirectional antenna could also work and might be easier to dial in. I did a setup with two directional antennas using their t-adapter. It did make the signal stronger by about 3db but it was also less stable. On the other hand, this same dual antenna setup could work when using 2 omnidirectional antennas. Here is the link to this duomax adapter where you basically connect two identical antennas to a single pigtail cable. https://frixtender.de/shop/frixtender-duomax-sets/
