Hi All
?
Who could remind me of the physical equation that calculate the lift off
distance depending on time different between the old and the new? AOS (e.g
ISS)?

Hi all, perhaps what appears to be a simple question but how far apart do I
need to space a 6 ele X yagi for 2mtrs (1 wavelength long) and a pair of 12
ele X for 70cms (horizontally spaced and 3 wavelengths long each). The
antennas are all homebrew and I know that as far apart as possible is the best
solution BUT this is not possible so just how far should I be looking for as a
minimum? I am trying to make sure that the de-sensing of any other radio
equipment is kept to a minimum (no fancy rigs here, an old FT817 for 70cms and
a FT-480r with a 25 watt linear when needed).
regards
Gus M0IKB
