This can get a position fix sitting horizontally, it just takes more time, so I assume that’s a good thing.
All that there is to do is parse, and software connect the serial NMEA to the vector mapping,
and it’s a functional GPS, which I think is a World first for these resources… otherwise please show me before I run to Hackaday
I can see a few traps if the online QFH antenna calculator was used.
* Not accounting for the radius of the metal stem. The calculator assumes the loop will pass through a PVC stem
when providing the result length of the loop wires. For this one, the radius of the stem needs to be trimmed from all elements.
* The bending radius input to the calculator includes the radius of the tube being bent, not just the radius of the former.
* It’s a loop antenna, so using any ferrite material nearby, or in construction including the coax sheath will probably detune, or break it.
