I would even buy one of those brackets. Mine from PLA is way too flexible.
P.S. looks like this antenna upgrade is very popular
pcbway can print in aluminum, and they have very reasonable prices.
The antenna wires are micro coax. Crimping them are stupid fiddly. The tool is also about $2000 US.
I wouldn’t use any of those, get a u.fl to SMA cable.
If I unstick the original antena, and restick it, will it hold on the original glue/tape, or do I have to reapply new glue/tape?
Depends on how careful you are in removing the adhesive. There isn’t much material applied on the antenna from the outset, so you may need to apply double-sided tape on your next application.
Not sure if I am just getting lucky or something but a friend of mine gave me some really old laptops to recycle. Just for the hell of it I ripped them apart and pulled out their wifi antennas, which used the same mini coax connection as the uConsole.
Coiled one of those up inside the console and I have vastly improved wifi performance despite the antenna being completely enclosed within the aluminum body.
It doesn’t look quite as cool as a nested folding antenna but it was significantly easier for me to do, and cost me nothing. I have since removed and discarded the stock antenna. Previously I had it attached to some foam to separate it from the body, which was better than stock but not as good as this laptop antenna.
