(RFMxx) antenna connector footprint -- one fits all: wire / uFL / SMA

A nice example for a very flexible antenna configuration shows Adafruit on her RFM95 boards:


You can use the same PCB footprint for …

… a simple wire as antenna


… an uFL connector


… or an bulky but stable SMA connector


I have not found a ready to use Fritzing part for this but I think it’s worth to make one!

In the meantime I found also a scale drawing on the Adafruit page (just front):

I think I got it done, not a real Fritzing part but working for me, it is a combination of the already existing (Sparkfun part “antenna”) SMA footprint, the uFL footprint and a bigger via:
