*Follow-up comment on ground independent Comet antennas...* So I'm pretty sure the model I have said this somewhere, but just in case you ARE looking for a mobile antenna that* does not require a ground plane,* here's a great video from Jason (Ham Radio 2.0) showcasing the whole line of "ground independent" Comet Mobile antennas at the 2025 Dayton Hamvention: https://youtu.be/qbvY05RsFe8
