20m END FED HALF-WAVE PORTABLE Ham Radio "DX" Antenna

20m End Fed Half Wave Ham Radio Antenna: Icom 703 with MFJ 16010 L-network tuner and 10.4m long insulated wire fed through a window and supported by a bush. The first contact using this antenna was with EI7GVB/Ireland, second contact with AA7VW/Oregon. No ground connection or counterpoise wire was used, and so it seems that this EFHW wire and MFJ L-Network tuner will work fine as a portable antenna on 20m (especially if it is installed in a more nearly vertical position).
