I have a tree line to deal with around the perimeter of the quad, so I’d have to be 20’ up. Once a ladder is no longer practical, I have to go to the roof.

Do not click links or open attachments unless you recognize the sender and know the content is safe. We went with outdoor APs but wall-mounted at about 10'-12' high. Depending on locations, we used either AP-365 with short arm mount brackets that extend out (AP hangs horizontally), or AP-367 mounted flat against the wall or with a slight incline down (we had to get the adjustable brackets cause the regular ones were out of stock). These are smaller than the buckets 27x or 37x series. We are still not at 8x so can't use the 37x. And we did take advantage of the buy 3 get 2 free promotion - Since they all have to be the same type, we got 5 of each. Since these tents get temporary power, another option was to run data to them and mount the APs inside the tents or on temporary poles - like it's done at conventions. But this way, the installation is permanent and the outdoor area will get coverage in the future regardless.

So we’re rolling out a major wireless upgrade using Aruba gear. A part of this rollout is to provide wireless coverage to a few outdoor spaces. One of these spaces is a quad flanked by 2 relatively tall buildings (about 6 stories). One of those buildings has a flat roof with no knee wall or parapet. The other has a parapet that has glass on the outside. Both are rubber-membrane roofs, so mechanical attachment isn’t going to fly. The building with the parapet only has about a 6’ clearance between the wall and solar panels, so I only have about 2’ to work with. Building 1: Flat roof Rubber membrane Roof has a minimal lip before you drop 6 stories Has a penthouse that is recessed from the side of the building that I can put electronics on/in Building 2: Library Flat roof Rubber membrane ~40” knee wall/parapet Rubber membrane goes almost to top of knee wall, then is capped with lead and a lightning ground Outside of wall is glass Our basic philosophy here is to separate the access points and antennas (ie use external antennas). We can’t attach anything to the face of the Library (Building 2) because of the glass and I don’t really want to have to maintain electronics over the edge of a building anyway. So, how are people installing antennas on roofs pointed down to cover quads 60+’ below? I’ll figure out where to put the AP’s and dress in the cables. Mounting at ground-level isn’t going to work. There is too much sidewalk and landscaping that would have to be disrupted. It’d be a budget-buster. Again, physically attaching anything isn’t going to be acceptable and in Building 2’s (Library) case, a large weighted sled will encroach on the service area for the solar panels. There will be several antennae on each roof. Here are photos. The photo of Building 1 is a few years old. The angle with the rocks isn’t the side of the building I’m putting the antennae. You can see that in the 2nd photo. I just included the 1st photo because it’s a better view of the roof: VENDORS: I’m already working with Aruba and an integrator. If you have mounting suggestions, please let me know, but there is no sales opportunity here.
