Re: Topband: Is PT0S still on 160M?

Topband: how high are very high voltages on antennas?

It is often mentioned that very high RF voltages are present at ends of dipoles, voltage nodes on loops, etc. but I haven't been able to find any guidance in the form of numbers. How high is very high? Assuming QRO power into a full size apex up delta loop, corner fed, vertically polarized,
