Topband: SteppIR for Tophat?

[Guy Olinger, K2AV]

The problem with a SteppIR would be that the tower tuning changes with
the band and frequency the SteppIR is set to.

At the very least the SteppIR would need to always be set for a
certain frequency when using the tower as an antenna, the same setting
as when the tower was tuned up for top band.

Also, there are very high voltages scattered around the top of any
tower used as a vertical radiator.

You would need to query the manufacturers whether there are any issues
they have with using it that way.
