Meshtastic antenna testing. Turned in to listening to the transmissions with my HackRF/Portapack

Recently built two Meshtastic nodes and tonight I was trying out a couple different antenna designs. Measuring them with my NanoVNA to make sure they match my mesh's frequency. In Arizona it is 906.375 MHz.
I got pretty low match numbers on this antenna. 2.3 SWR, jumping around between 40Ω and 75Ω, and fairly capacitive on the smith chart, but it is receiving the mesh traffic including the big, loud transmissions from in my house and on my roof clearly on the waterfall of my SDR with portapack. This tells me it will be decent for Mobile solar node, Heltec v4.
