We have obtained the basic data for the design of VHF direction finder locating lightnings at close ranges. As a first step, the field strengths of lightning discharges on 48MHz and 78MHz were measured, then we have chosen a frequency of 74MHz for the direction finding operation and measured the horizontal and vertical field strengths on 74MHz. The VHF direction finder using the Adcock antenna is found to be able to determine the bearing of lightnings at the range less than 160km with a bearing error less than 2°. The obtained directions by the VHF direction finder (200kHz bandwidth) showed a good agreement with the radar data.
