I am a web designer with a background in IT and electronic engineering. I love the challenge of making or inventing little (and sometimes big) improvements to my motorhome. As a web designer I need regular internet access. We don’t often stay on camp sites and often use FON or other free wifi connections. Often these are low or poor signal due to the wifi source being some distance away or obscured by buildings or trees.
Previously I had used a directional USB antenna fixed to the side of my van via a suction mount. This has worked well until the antenna met with an accident and fell off damaging the cable. The USB method is still an excellent way to connect a single laptop but falls short if phones, tablets or a second laptop need to connect.
So I needed to find a solution that will still suck in the distant wifi signals but allow multiple devices to connect at the same time. The guys over at www.motorhomewifi.com have created a packaged system that does exactly that. It costs £159 +postage so I though I’m sure I can create something similar for less money. This article is in no way intended to take away from what the guys at Motorhomewifi.com have created. If you want a packaged system that works out of the box then go for that. If you wish to save some money (up to 50%) and have an hour to spare to configure it yourself then read on.
I started searching for the antenna part and noticed that the motorhomewifi.com antenna appears to be made by a company called Ubiquiti (model Nanostation Loco M2 8dbi) and their router appears to be made by MikroTik (model Map 2N). I read a few reviews that the Map 2N was not easy to configure. Then discovered that Ubiquiti sell a matching wifi router that goes with their antenna and its easy to configure and was cheaper than the Map 2N. Further research revealed that Ubiquiti is a US company and have been making wifi kit for commercial and professional applications for over 10 years and have a great reputation for the quality of their kit.
Here’s what’s needed:
Ubiquiti NanoStation Loco M2 airMAX Outdoor 2.4Ghz 8dBi antenna: £42.00
(Or the 11dbi antenna: £71.44 – more on what the dbi mean later…)
Ubiquiti airGateway WiFi PoE Access Point (150Mbps N): £19.71
PoE 12v injector adaptor: £2.95
12v power lead – DC 5.5 x 2.1mm plug to car cigarette plug: £3.79 **
3m flat cat5e network cable in white (other colours plus shorter and longer lengths are available): £2.49
Postage: £3.60
Total: £70.75 (or £99.89 for the larger antenna)
** I made this lead up myself from an old DC power adaptor I had and permanently connected it to a 12v supply (via a 1amp fuse) in my motorhome so didn’t actually buy this part. The DC 5.5 x 2.1mm plug is a very common plug but very very similar to the 5.5 x 2.5mm plug so ensure you buy the right one!
I also manufactured my own mount for the antenna but you can buy the proper suction mount (identical to the Motorhomewifi.com mount) for £15.37. Ubiquiti also sell pole mounts as well which are cheaper. So with a suction mount the total cost is around £86 for the small antenna. Photos below show my self made mount. The pole I already had as its a support for my drop-down bed and the wall mount was a caravan aerial wall mount costing £10.99 from my local camping shop. The antenna is attached to the pole using a couple of tent bands which are very strong elastic bands. The pole allows the antenna to be nice and high (above the van height) and also allows the antenna to be rotated easily.
I bought the flat network cable so it fits through window and door seals better than the fat round cables.
Here’s more details about the Kit:
Ubiquiti NanoStation Loco M2 airMAX Outdoor 2.4Ghz antenna
This is available in 2 different models – 8dbi and 11dbi. The figure indicates the width of the beam of the transmitted signal. The 8dbi antenna with its wider beam will pick up signals from a wider (approx. 60 to 90 degrees) area but is less sensitive to weak signals. The 11dbi antenna has a much narrower beam and thus will need more care in aligning the antenna.
Here’s some technical stuff about Antenna gain and strength: A directional antenna can be thought of as a radio frequency camera lens. A long lens (high gain antenna) is harder to aim because it has a smaller field of view and it requires a stable mount. On the other hand, a high gain antenna works in your favour twice. First it focuses your transmitted energy, an 8dbi antenna increases your effective power by a factor of 10^0.8 (6.3 times) and a 11dbi antenna by a factor of 10^1.6 (39.8 times), and it gathers in more energy to send to the receiver (by the same gain factors). Finally, the one everyone usually forgets, the directional antenna helps reject unwanted signals arriving from other directions so is less affected by interference from other wifi sources.
So, the 8dbi antenna for easier set-up (about 2 or 3 min) but is less sensitive or the 11dbi for weaker signals but takes more time to set-up (about 4 to 8mins). The 11dbi antenna is slightly larger and costs much more at £71.44.
Both antenna’s have a signal strength meter on the back with 4 LED’s so you can tweak the position for best signal. In my experience the LED’s are hard to see in daylight and didn’t really help that much.
My choice was the 8dbi antenna to try and if I found I was left wanting then I could send it back to change for the 11dbi and pay the extra.
The antenna also comes with a PoE injector which is 240v mains electric so is not needed. More on PoE later…
You can buy the 8dbi antenna HERE from Amazon – or – the 11dbi antenna HERE. You can buy the suction mount HERE
Photos above show the 8dbi antenna (left), 11dbi antenna and the suction mount.
Ubiquiti airGateway WiFi PoE Access Point
This small device (around 5 x 6 x 3cm) connects via the network cable to the antenna. It takes the signal from the antenna and creates its own private wifi signal which your devices then connects to. There are several different airGateway devices available including one with an external antenna and a PRO model but I choose the basic model with the internal antenna as it only needs to be used within the small confines of my motorhome. It’s also cheaper!
You can buy the AirGateway from Amazon HERE.
PoE – Power over Ethernet
This is a method of using normal network cables (aka Ethernet cables) to power devices with low voltage over short cable runs. Both the above devices will work from a 12v DC power source such as my leisure battery and consume around 500mA which is pretty low. I ordered what’s called a PoE injector from ebay. This takes the 12v DC from the battery and injects it down the network cable to the airGateway and then passively onto the antenna. Thus minimal cables are needed. The PoE injector comes as a pair of cables – see the left photo below – and only the left hand one with the female DC socket is needed.
You can buy the PoE adaptor from Amazon HERE (left photo)
You can buy the 12v power lead HERE (middle photo)
You can buy the flat 3m network cable HERE (right photo)
The items have now arrived and took about 1 hour to set them up. Some extra trial and error configuration changes to optimise the results and it all working fine. However on a field test, the new 8dbi antenna did not pick up as much weaker signal as my old usb antenna. The old usb antenna is rated at 36dbi which I never quite believed but its certainly better. So the 8dbi is being exchanged for the 11dbi antenna. The difference between 8 and 11dbi does not sound much but the db scale is logarithmic so 8 to 9 is double and so on.
Here’s the steps to setting up the Ubiquiti hardware
There are videos showing each step to view and its a good idea to view the videos at full screen to see more detail. I had a bad cold when making these videos so I hope I am clear!
Step One – Setting a static IP address on your computer
Vast majority of computers will use a dynamic IP address to connect to the internet. To connect to the antenna we will need to change the IP from dynamic to static. The new static address should be set to 192.168.1.10. This only need to be changed for this single setup and will be changed back in step 4.
Step Two – Setting the IP address of the Ubiquiti Nanostation M2 antenna
In this step we connect to the antenna via a normal web browser and change the IP address on the antenna to 192.168.2.1 and configure the setup to work with the AirGateway device. We also change the password for the antenna. The photo shows the antenna only connected to my laptop. The antenna can be used like this if you don’t have other devices to connect to the wifi.
Step Three – Connecting the antenna to a wifi access point
In this step I show you how to connect your antenna to a wifi access point. At this point we do not have the AirGateway connected and we are just testing that the antenna can connect properly.
Step Four – Changing your static IP address back to dynamic
Next we need to chnage the static IP address that we set in Step One back to dynamic
Step Five – Configuring the Ubiquiti AirGateway wifi device
Next you need to disconnect the antenna cable from your computer and connect it to the PoE socket on your AirGateway, then attach the DC power to the PoE adaptor and plug that into the AirGateway. The AirGateway should have a white LED which lights and after approx 40 seconds will turn blue meaning the device is ready to be used. Next we connect via wifi to a the AirGateway access point which is called www.ubnt.com. At this point this is an open connect and no wifi password or key is needed.
Once connected, open your browser window and connect to IP address 192.168.1.1. Login to the device with login of ubnt. Next change the password on the device. This is not the wifi password but the password on the device. Next change the SSID or name of the device. Make this something you can remember. Next add a wifi password. This must be a minimum of 8 characters. Then reboot the device. Connecting to this via a browse ris pretty much a one-off setup so once completed you don’t need to do this again. The photo below shows how the antenna is connected to the AirGateway.
Step Six – Connecting to a wifi access point via the AirGateway
At this point it is probably best to reboot all your devices – computer, antenna and AirGateway. Then start everything back up and connect to the new wifi access point you created earlier. Connect your browser to IP address 192.168.2.1 which is the IP address of the antenna. Then select your prefered wifi access point and connect.
Buying the equipment
I have added links to the different parts on Amazon but in truth I bought mine from different suppliers such as ebay and Broadbandbuyer.co.uk

Hi Im not sure here how to get a reply do I need to subscribe?
my query is are you operating your Ubiquiti airgate wifi PoE access witha PoE type injector adpator so NO mains electric used?
Yes thats correct. The 12v adaptor goes into the POE injector adaptor and then straight on the airgateway. The mains adaptor that comes with the airgateway is not needed unless you have permanent mains hookup.
However, the ethernet connector where the POE injector connects does not have the usual clip to secure the connector and it can come off easily. In use it doesn’t come off that often but in my case I did hook an elastic band around the 2 items to hold them together.
Many thanks Steve.
I tried to use this: MikroTik Low Cost Passive PoE Injector ..with a 12 volt DC power lead+ 2.1 jack, hooked up to a ‘bench’ 12volt DC power supply but was unable to turn the Nano M2 on but the M2 does power up using the supplied mains PoE….is this an issue regarding the amps of the 12 volt supply? I’m scratching my head right now wondering where the problem lies….incidently I asked the Ubiquiti guys the same question and came up with blank answers…”third party devices”. and so on…..
PS, have you got a diagram of your connection process… I’m more than happy to subscribe to your ‘special fund’
I don’t have a diagram, but if your bench supply is not supplying enough current or the draw is causing voltage drop then this would certainly cause problems. What happens if you connect the M2 directly to the POE injector?
sorry Steve not totally understanding what you mean, ..connecting an cat6 lead into the injector’s cat6 connector and connecting the other end of the lead into the M2 plus connecting the 12 voltDc power/ jack into the female jack connection
also taken another look at the 12 volt bench supply… input 240v ~ 50Hz mains, output: 3,4.5, 6.0, 7.5, 9, 12.. no where does it mention a DC output I just assumed that a 12 volt output would be DC
Hi Steven,
I was just about to buy an I Boost System and as I live in Ireland it was going to be a lot more expensive than the UK because of the shipping cost. When I saw your post and videos and the way you have explained it all I’m sure that I can do it. I’m going to have a go anyway and I’ve ordered the items needed. One thing puzzles me though in one of the videos you connected to BT with Fon. Would I be able to do this as I’m not a BT customer?
Very Best Regards,
John
Hi John
You can only connect to a BT-with-FON if you have either A BT account or a FON account. But you can still connect to any open wifi access point (or a secure access point if you have the password) that is available such as a campsite, cafe, fastfood place, pub etc.
Steven
Thanks Steven,
Do you know if people living in Ireland can get a FON account? If so how would I go about it. I spend a of time in France and I believe that FON is really useful there.
Thanks again,
John
Yes FON is widely available in France. You used to be able to buy a stand-alone Fonera device which shared out your home wifi to other FON users which in return gave you a free FON account, but FON appear to have discontinued this product, but you can but FON vouchers as cheap as €20 for 30 days. We were in the Dordogne region last year and strangely found the FON network (provided by SRF) almost non existent, but the Orange network was everywhere so bought a 30 days pass from them for about €19 and that worked very well.
Thanks very much Steven for the quick replies. I thought that I had to buy a Fonera device but when I checked on the Fon website after speaking to you I noticed that Ireland isn’t even mentioned as one of the countries the company deals with. I didn’t know that they had discontinued the Fonera router. I’m still going ahead with the system you have because as you said it will be good on campsites or for close by bars and cafes that offer free wifi. At the moment I have a Huawei Mobile wifi device and use a three.co.uk data only sim. I find this very good but it will be best to have the options. Thanks again for your help and I wish you all the best and happy travels.
Kind Regards,
John
