I'm hoping Bill will chime in here - he's a real expert.
I recommend a coaxial cable with a PVC-IIA outer jacket, at least 95% shielding, tinned shield & conductor
In my order of preference, I use:
RG213U: (0.405” ∅ OD)
RG8X: (0.245” ∅ OD)
RG-8X, RG-8U, RG-213U, or Belden 9913 are all good VHF
I wouldn’t use RG-58 (0.195"∅).
