What about mounting a diversity between the two traces? Is that possible?

Hi, can you tell the pourpose to solder a 0ohm resistor between the traces and remove the capacitors used for the PCB Antenna as PCB Antenna is no more used due the trace cut? Thanks

Interesting fix.

Ha, I did the same some time ago, but only to test an antenna kit, not for a product.

Similar results. And soldering tiny stuff is fun.

Hi!

I guess you had little choice since the box was metal. It could also be worth using a Pi Compute Module instead since that comes with the RF connector already fitted. There are "baseboards" that the compute modules can plug on top of, to give the same form factor of the original Pi.

For anyone thinking they want to do this on a Pi, it might be worth pointing out that there is a risk of exceeding the allowed power level (which is why they have the solder resist on that connector), and it's a quick way to damage the board too, since an 0201 resistor is not normal : ) That took some skill to do, not easy the first time around.

Anyway, good work, glad it worked out for your need.
