As part of their Tonight at 8 series, the RSGB had a video presentation recently from Neil, G4LDR about getting started on the amateur radio microwave bands.
The talk itself is about 1h 15m in length and it is followed by a 20-minute Q&A session.
The video covers propagation, antennas and equipment for the amateur bands from 1.3 to 10 GHz.
