Tripod mounting adapter for Cisco Meraki MR outdoor access points

I needed to find a solution to swapping multiple outdoor AP and antenna combinations on the same tripod. Specifically MR86 with MA-ANT-20 dipoles and MR86 with two MA-ANT-25 directional antennas. Quick swapping was a key requirement. Some coverage areas required directional pattern while other locations with low traffic and low client density would really benefit from omnidirectional coverage.

MRs ship with standard pole mounting hardware, which is great for permanent installation, but it didn’t allow fast swapping of the AP and antenna sets. Also, pole mounting kit requires tools, which is not practical as it add additional weight to your survey backpack.

Please excuse the DYI approach. I did this during UK’s second COVID-19 lockdown. Shops were closed, tools were limited and I had no access to my lab.

You are smart people, so I don’t need to stress this point, but please don’t take this write-up as Cisco’s official guide or recommendation. This is just me trying to find a solution to a problem.

So, what’s the solution?

Let me show you the final adapter and we can then look into the detail.

Under the hood

It all started when I spotted my wife’s aluminium 16 mm gardening tubes;-) I realised they were perfect fit for my tripod. They slide nicely inside the top tripod tube about a couple of inches (5 cm) or so.

What would I improve?

If I were to build a second iteration of this adapter, I would add a safety wire and attach the AP mounting bracket to the tripod. I would call this mandatory, especially if you are not the only user of these adapters or if there is going to be a person stood underneath the tripod.

Apart from that, it works really well, it is rock-solid, and allows me to swap the MR with omnis and MR with directional antennas in less than 10 seconds.

Affordable tripods for occasional Wi-Fi site surveys

As I mentioned in my battery pack review, I am fortunate to rely on our field engineers and partners when it comes to predictive design validation, wall measurements and AP on a stick surveys. Having said that, I enjoy going on site a few days a month and staying close to our projects. Which leads me to yet another blog post from the “affordable series”;-)

This time I tested 3 tripods. Key factors I considered were value for money, build quality, and suitability for outdoor surveys ability to hold anything from an indoor or outdoor AP to a camera.

Summary

I decided for tripod (C). It is high enough for outdoor surveys, rock-solid, and very stable. I also built an adapter that allows me to easily mount any outdoor Cisco AP (Catalyst, Aironet or Meraki MR). Here is more about my outdoor Meraki MR universal tripod adapter. Stay tuned for the Aironet and Catalyst one.

The only downside is its weight. Also, watch out for packaging. The first one I ordered arrived with the bottom of the box open and the head, where you insert the 1/3″ and 3/8″ adapter, was damaged. So, it took one return to get an undamaged one.

 All three tripods are supplied with 1/4″ to 3/8″ adapter.
