[aprssig] Antenna separation

[Patrick]

'Far apart' isn't always possible, but remember RF travels in waves, and 
as such for every wavelength you will have nulls where the signal is 
almost completely 0 as seen by another antenna with the same 
orientation.  By locating the antennas in each other's nulls on 2m you 
can more or less completely negate the interference.
