    3D counterpoise for AsDip 40 \ 20m. Mechanically unloads the insulator (with a tubular mast). Provides a wide band with a VERY small size. It is possible to add more bands.

    Hi RW4HFN,
    For better vertical supporting the central pole, I tried your model by rotating the capacitive hat by 90 deg (pyramidoidal vertical view).
    Resonances changed a little and the Axial to Transversal ratio on 40M increased a bit from ~1.5 to ~3 dB.
    How do you like it its way?
