DIY: External antenna for Globe Tattoo USB dongle
Vacation time. Time to relax and disconnect. That was the original plan. But work always find its way back to me. I needed internet connection to do some content editing for an online shop. Unfortunately here in Bontoc, Southern Leyte, a stable internet connection using the Globe Tattoo usb dongle cannot be achieved unless you stay outside your home to get a better signal. I have read before, articles about modifying these usb dongles to have an external antenna, but I never had the reason to actually build one because I already get a decent signal in Cebu City. Now that I’m in the province area, it’s DIY time
The procedure is very simple.
Things you need.
1. External Antenna. I purchased this one from CD-R King for P250.00
3. Philip screwdriver
4. Wire cutter
5. Soldering kit and lead
Lets get started.
1. I have no idea which model I have but this is how I opened the usb dongle. On one side there are hidden screws colored white.
Remove the screws and carefully open the plastic case from the side. It’s just a snap on plastic case so be careful not to break it.
3. Then flip the usb dongle to the other side. This is what it looks like but without the wires.
Unfortunately I forgot to take photos of the usb dongle before I soldered the wires in place. Look at the photo of the cable in the materials section above. I remove the female connector and peeled off the insulators. I then soldered the ends to the usb dongle. Please refer to the photo as to where to attach the ends.
5. After that I put back everything into the plastic case. It was a bit of a challenge but after some additional modifications to the inner part of the plastic case, I was able to pack everything back into place.
The download speeds are not that spectacular. You can’t do anything about that. Whatever bandwidth Globe has decided to dedicate to this area is what you’ll get. The purpose of this project was to get a better and stable signal at HSDPA/WCDMA instead of the GPRS signal I get without the external antenna.
I will assemble a proper mount for the external antenna later this afternoon and put it somewhere higher to get a better signal. Something that is easy to lower down in case of thunderstorms. I’ll post updates as soon as I gather more data.
I would like to try this setup with an actual outdoor wifi antenna like this the one found here: http://bit.ly/PncfU8
