    R ST D1 D2 D3 D4


    Boom length 230mm Size 3x8x230mm
    Rod diameter 2-3mm 0.65m length
    Mid frequency 1297 MHz.
    Gain over Dipole 8.5 dB
    Beamwidth 51° (-3dB) ----------------------------------------------------------------------------

    In DG2GAJs design it is not clear, but he shows 2 lines (Alt 186) for the dipole. I asumme that this could indicate a folded dipole! These are used in other designs to get the Z right.



    Why don't U send an interesting bul?
