I initially supported a dipole on an outdoor structure as a temporary receive antenna due to QRM from a neighbour on the main antenna. However, this provided an opportunity to talk about ideas for stealth antennas. Note: This only covers dipoles, fan dipoles and loops; vertical stealth antennas may be covered in a future video. Additionally, when talking about loops my maths may be incorrect; a loop should be a full wavelength on the lowest band of operation. Dipoles are obviously a half wavelength, so whilst the frame discussed will fit a 20m dipole, it wouldn't necessarily fit a 20 or 30m loop. I clearly needed more caffeine before recording this :)
