The voltage allowable on 75 ohm 1/2 inch hardline far exceeds the
voltage allowable for RG-213. No problem at the limit of 1500 watts for
the ham bands.
Even RG-6 will withstand 1500 watts with no problems.

Careful, 75 ohms was picked for cable TV receiving Coax because it was lower
loss then 50 ohms but it could not handle high power as 50 ohms could. 50 ohms
is a power, loss compromise. 35 ohms For high power high loss, 50 ohms
compromise, 75 ohms low loss low power.
