I need to re-visit the Building 1 situation. We have put wall-mounts as a quick-fix. The problem is the initial install. We're trying to do as much of this in-house as possible. The antenna would need to be between on the 3rd floor (toward the top of that) to clear the treeline, so we're looking at 35' above ground. That's why we started looking at the roof again. It's much easier to access. Given our winters, I just want to keep anything that may need maintenance out of the snow and away from the edge of the building.
By the way, as far as the Library - there's no chance to put anything on the side of the building. You know construction these days - form over function. 100% glass curtain walls. There's only a 1" gasket between panels. -Brian From: The EDUCAUSE Wireless Issues Community Group Listserv <WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> On Behalf Of Enfield, Chuck Sent: Friday, August 28, 2020 5:29 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [EXTERNAL] Re: [WIRELESS-LAN] Antenna mounting suggestions CAUTION: This email originated from outside of Salem State University. Do not click links or open attachments unless you recognize the sender and know the content is safe. The library is an excellent candidate for a non-penetrating roof mount. If you google it you'll find many options. Don't get crazy with the size or you'll have to have a structure engineer make sure the roof can handle the spot loading. I did the wind load calculations and I think a 100MPH wind could result in 23lb of lateral load on an AP-375, so there's no need for tons of ballast. Also, put a pad of some sort (usually available where you order your mount) between the mount and the antenna to project the roof membrane. For Building 2, if you're trying to cover that smallish space between the buildings I'd definitely recommend wall-mounted panel antennas. Put the AP above the ceiling inside, drill a ¾" hole in the wall, and mount an ant-35 (or something similar) flat to the wall outside. If you paint it to blend in with the brick it will almost disappear.

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.
