Shunt fed tower

Webof the tower acts as a capacity hat. I have read of another 3el SteppIR user who has found an extra bonus of his antenna in so far as any tuning to different bands on the SteppIR enables him to tune his shunt fed 160m antenna to different frequencies on top band. Logical, but very useful!
