Dielectric loss of polyethylene coax at HF is negligible.
A lower dielectric constant does reduce conductor losses, so lower 
capacitance corresponds to lower losses, but only if the construction is 
otherwise identical.  Coax that is much larger in diameter will have 
lower losses than small coax even if it has more capacitance.
