Came up with a silly idea while reading this article. I'm not going to try to explain it (not that I could) but this article talks about the curious properties of graphite material (like the stuff you use in a jammed lock to free it so the key will turn). Evidently the electrons flow of "ultra-clean graphene' act like a "Dirac fluid," in which thermal conductivity drops as electrical conductivity increases. - Not that I grasped it all, but the first thing I thought was "what if you filled a 102" stainless whip antenna with graphite? Could that increase your range? Silly idea perhaps, but that's what came to mind..
Scientists determine that electrons in graphene defy established laws of physics
https://www.earth.com/news/scientists-determine-that-electrons-in-graphene-defy-established-laws-of-physics/
Researchers have found that electrons in graphene can break a long-standing rule of metal physics, separating heat flow from electrical flow by more than 200 times at low temperatures... .. ... The same physics that splits heat from charge could make graphene useful in sensors built for extremely weak signals.
When carriers move collectively, a tiny disturbance can redirect the whole current pattern instead of nudging isolated particles. ... Next steps will likely push toward cleaner devices, broader temperature tests, and sensors that use this collective electronic regime on purpose.
For a second there, I didn't know what kind of whip you meant. I was worried.
Heh! The wordplay wasn't intentional, but I hear it now.
