My 132 foot dipole is fed by lengths of 450 Ohm line of lengths depending on
frequency. The first part acts as a matching section to achieve 50 Ohms.
This feeds an electrical 1/2 wavelength 450 Ohm section the 50 ohm
impeadence is seen by the rig, while maintaning a 9:1 swr on the 1/2 wave
section. 450/50=9:1

All my feedlines have a 9:1 SWR by design.

Really, and how is that?
