Right tool (antenna) for the right job - Patch versus helical on M2 for ground use

The idea for this post came to me from seeing all the nice enclosures people are 3D-printing for their Emlid M2’s, using the drone helical antenna for keeping the size of the setup down. I have seen numerous people claiming that the drone-antenna is just as good as a classic patch antenna for classic surveying on the ground. Looking at data-sheets and radiation plots it simply couldn’t be true. So, what to do about that? Experiment of course! For this experiment I have selected 2 antennas: T…
