Huawei E303 external antenna?


Does the Huawei E303 support an external antenna connector?


Hi @skeller, our E303 in the store does not support an external antenna.


Is it “hackable”? Does the circuit board support adding a connector?


Wowza! It is hackable! I opened one up and there is an antenna input. Although it is a cheap one, the antennas I tried fell off pretty easy. Nothing a little duct tape would fix :slight_smile: Thanks for intriguing me enough to check it out.


Awesome! It looks easy enough to replace with a better uFL connector if necessary. I guess I need to give one a whirl and see how it works.

Thanks for checking!!! :grinning:



How did you get the back cover off without breaking it? I could not seem to find any access point.

I’m away from my desk currently but recall two screws near the USB then using a small device pry bar to unsnap the casing. We have one of those iFixIt tool kits in the office.


Thanks man,

OK, just saw the screws, they were covered with a cosmetic tape.

Looks like a T1 or T2 torx .
