If you model the RX antennas with the TX antennas in the model, and then without, you can see the change in RX pattern, usually with the loss of deep nulls. Some situations you can get extreme interactions and reversal of pattern or loss of any directionality. Better to model with your dimensions, your specific conductors (include any conductors in the area, not just TX antennas) to see if the model suggests interaction.
There is no rule that works everywhere, other than the general statement that TX wire antennas CAN modify the pattern and performance of RX antennas in proximity. 73, Guy On Wed, Feb 16, 2011 at 1:25 PM, <k...@nc.rr.com> wrote: > All, > > I know it is important to keep RX antennas like flags, pennants and K9AYs > as far away from TX antennas as possible.
