Weekend Antennas No. 3 A Magnetic Slot for 40 Metres magnetic slot™s 1.8 dBi Œ but this maximum gain is at 90 degrees elevation, straight up! Gain at 10 degrees elevation is Œ5.3 dBi, some 4.7 dB worse than the Magnetic Slot. The dipole will perform well as a near vertical incidence skywave (NVIS) antenna for local communications, but the Magnetic Slot is a better choice at the low AN OPEN LETTER TO AMATEUR RADIO - K4SX AN OPEN LETTER TO AMATEUR RADIO.
