This holder mounts to two of the standoffs in the front part of the mower. The standoffs are drilled and M3 heat set inserts (I used BOSSARD 1386743) are pressed in. M3 screws are then used to secure the holder.
The PCB to the left of the holder is a custom power supply + UART isolator and level shifter board I designed. It is the reason I couldn't use all four standoffs to mount the antenna like most people seem to do.
I used this IMU breakout board: https://www.pololu.com/product-info-merged/2736, mostly just because I could source it easily. To mount it, an M2 heat set insert (BOSSARD 1386727) is pressed into this holder. An M2 nut would probably work just as well (possibly with a slight change to the holder design), but I didn't have them handy.
The resulting antenna offsets are:
export OM_ANTENNA_OFFSET_X=0.290
export OM_ANTENNA_OFFSET_Y=-0.030This repository contains some notes about my Mowgli build: https://github.com/ondras12345/mower/.
