My anecdotal experience is the same. I've had performance problems with
antennas looking through insulated steel guys and wonderful performance from
a stack looking into Phillystran.
Many letters and articles over the years have been written about SWR
problems with steel guys (watching the SWR change as you rotate a keyed
antenna through a 360 degree rotation). There's got to be something to it.
