[Lowfer] Hex loop calculator

[John Bruce McCreath]

I can’t find an online calculator for a hexagonal, multi-turn receiving loop.
If anybody can point me to one, I’d really appreciate it.  The antenna is
for VLF reception and it will have twenty turns on a wooden hex frame
with a maximum dimension of 40 inches across.  That’s as big as I can
manage, which will fit into my SUV’s cargo area!
