No stainless steel hardware to seize. However the brackets are lighter gauge steel than other Cambium sectors, and not hot dip galvanized. Does anybody know what is under the silver paint? I'm assuming zinc or cadmium plating? I'd rather they not paint them, and I sure hope there is some decent plating underneath, or we're going to have rust problems.
No metric hex key needed, but you will need 10, 12 and 13 mm wrenches. I liked it better when everything was 13 mm, although the hex key was a problem if someone had to replace a radio up on the tower.
The bracket design makes it difficult to get a crescent wrench on some of the nuts, the tower guy will probably need a 12 mm socket and a 13 mm box end. Lots of tower guys only carry a crescent wrench, channellocks, pocket knife, and electrical tape, so they're going to reach for the channellocks.
The brackets are a bit flimsy IMHO, in particular I think the M8 bolts in the middle of the long slot in the upper bracket are a weak point. The bolt head isn't wide enough, and that slot (which is already too wide) could open up given how long it is.
The rectangular bracket configuration with no diagonal brace, relying on tightening the screws really tight, is not a good design but many sector antennas have the same problem.
I wish they included two bottom brackets, I would substitute it for the adjustable top bracket for a little more rigidity. Not sure why we need downtilt on a sector with 23 degrees vertical beamwidth anyway, unless the tower is on a mountain and we are pointing down at the valley, which would be pretty cool. The adjustable bracket has tick marks but no degree markings.
The AP comes with an LPU style PG16 metal gland except it has a rubber insert, which is good if you don't intend on using their LPU and the Superior Essex BBDGE cable. The rubber insert is already slit, so you can get an RJ45 terminated cable through it. I guess if you get an LPU kit, it comes with the grounding glands already on a premade cable.
The AP just has a plug over the timing port, it doesn't come with a second gland. So you might need to procure additional glands.
You might be able to force a 16 inch Cambium coax jumper to reach (if you don't care about bend radius), but I really think it needs more like a 24 inch jumper.
They give you 2 ground screws, which are still underneath when assembled but at least they are hex bolts. But both of them seized hopelessly when I tried to loosen them. This is not good! The bolts are stainless steel, but I assume the tapped holes they go into are something like aluminum. Not sure how I am going to ground this AP.
Next step is to see if I can set the timing parameters to coordinate with 900 FSK, there are other WISPs in the area using it, and I can't assume they will upgrade to 450i.
I do notice the SM has a place on the back to mount it to a J-pipe or pole with a hose clamp, this doesn't seem to show up in any of the photos on the website or in the literature.
