## Notes

- U.FL is the tiny snap-on RF connector on receivers, VTXs and GPS modules; FPV pigtails run from it to an SMA or MMCX.
- Mated heights and cable ODs are from Hirose's catalog. The receptacle body outline is drawn but not stated in text, so no file.
- IPEX MHF1 is a compatible connector from another maker; MMCX numbers are not included (no maker drawing in text was available).
