WebJan 19, 2015 · Distances are going to be relative to wavelength, so an HF antenna will be more difficult than VHF or UHF. For the antenna to be really in the clear, two wavelengths is a good rule of thumb. You can probably get as close as a quarter wavelength and still make things work with some adjustments to the tuning. WebIn telecommunication, the free-space path loss (FSPL) (also known as Free Space Loss, FSL) is the attenuation of radio energy between the feedpoints of two antennas that results from the combination of the receiving antenna's capture area plus the obstacle-free, line-of-sight (LoS) path through free space (usually air). The "Standard Definitions of …
