I highly recommend using a normal SMD 10pF to 100pF ceramic capacitor, depending on frequency. They’re already used on the board, and tend to be cheaper than zero-ohm resistors, as we buy them by the bazillion rather than the handful.

I’ve typically used RF switches for this purpose, but that’s also when it was necessary to allow the antenna selection to be changed “in the field”. But for cases where the antenna selection is a manufacture-time option, I’m considering simple zero-ohm resistors.
We would like to do wave soldering for the through hole components. All through hole components are top side of PCB. Only test points, which require mask during process, are on the bottom side. So there is a extra labour cost at adding and removing the mask. Can we do wave solder the through hole parts without masking it?
My EDA software (PCAD, but I guess others do this too) adds thermal reliefs on vias in a copper pour. What’s the use? Vias aren’t soldered.
