UniFi NEMA Enclosure

UniFi NEMA 4X Access Point


I am looking for some constructive criticism on a project I elected to do after being told that a contractor would bring in a new wireless AP into our network, which we would manage after install, a product standard that our Network staff did not want to support. (Primarily myself)


Currently we utilize Ubiquiti and Meraki access points, but through an agreement of my upper management, we have agreed to utilize Ubiquiti in special outdoor applications and Meraki in nearly all standard applications (mainly due to utilizing over 200 Ubiquiti PtP/PtMP devices – the trust has been built).


Wi-Fi requirements for several warehouses:

            10 AP’s

2.4GHz and 5GHz

Directional (90 degree required)

            I’m aware of the 90-degree 2.4GHz/45-degree 5GHz antenna)

IP67 minimum (NEMA 4X suggested)


I wanted to run with Ubiquiti’s BaseStation XG, but since 2.4 and 5 GHz was required, those were off the table… So, I made my own, with the UniFi AP AC M with the UMA-D Antenna.


Hopefully the pictures attached will tell the primary portion of the story.

            Parts list below if anyone is interested in copying.



What I would change If I were to do it over again:

  1. Purchase the screws and nuts to fit on the backing plate
    1. The way I did it works great and is solid, the look is just not too professional
  2. Add a second vent at the top of the NEMA enclosure for quicker temp changes
    1. All of my AP’s will be in the shade, so I am less concerned

Part Cost with current price/tax/shipping to my location:

            L-Com.com: 276.47

            Amazon.com: 219.73

            Hawkusa.com: 31.90 + shipping (a shipping cost was not added for a quote)

                        FYI: Previous order for four of them led to a $7.95 delivery with no tax.


Total cost ($528.10 + a couple of extra bucks for shipping the vent). This Is about a thousand dollars less than the BaseStation XG – I know, apples vs. oranges… but still about 800 dollars less than the access points we would have paid for from the contractor that we didn’t want to support. Saving 8K on access points for a location that has a low client count is great. Plus, it only took a couple of days to do the work (off and on). If anyone has questions, I will be happy to comment. If in the future, there are any failures/changes I will update my findings.

I'm only curious why you took outdoor rated equipment and put it in an enclosure. The mesh AP and that antenna are designed for exposure.

on ‎03-29-2019 11:03 AM
Because they are rated for water/environmental resistance NOT waterproofing. I have installed plenty of IP67 and IP68 IP cameras with proper installation and additional water resistance measures like silicon. I have still had cameras died due to water damage and corrosion. I am not say they will fail, I am just saying that it is not 100% protection against the elements. This goes especially in places with harsh climates. Also, those ratings are done in lab environments with pure water. I appreciate the steps cwindsor07 made to further protect his equipment. The only thing I would add, would be those moisture absorption packets inside the box.

Thank you both for your posts. I love the idea for the moisture packets, I think I’ll buy some. 


Russwazhere made the exact point regarding why I did this. I was mainly concerned about corrosion on the port and board since the AP’s aren’t protective in that manner.


Thanks much.

I can't argue that 'water resistance' are words easily claimed by 3rd party products.

Neither can't be argued that Ubiquiti builds on years of experience with enclosure design.


We have plenty of early UAP-AC-M units in extreme outdoor conditions, baking away under very harsh sun rays which burns your skin in a few minutes.  During the rain season it's getting its weekly wash by torrent rain and wind, conditions where you even can't hear the person if he were shouting directly in your ear. 


Standard antennae get a bit brittle after a few years, but not a single unit shows corrosion on the RMA connectors and not a single one has a drop of moisture getting in.


I agree your solution with the UMA-D looks slick and does its job, but for installation with just the standard omnis, I won't spend too much efforts myself.

glad i wasnt the only one who thought this ^

I feel I should wrapping myself in bubble wrap and applying sunscreen 6-7 times per day. Looks ok i guess
