Weekend Antennas No. 3 A Magnetic Slot for 40 Metres Weekend Antennas No. 3 A Magnetic Slot for 40 Metres As we approach the solar cycle minimum, the lower frequency bands become increasingly important for DXing. Many amateurs use wire antennas on the 40m band and below, typically the horizontally polarized dipole and its variants such as the inverted V, W3DZZ and G5RV.
