Hi,
I am using a object oriented version of NEC (SuperNEC 2.9) to simulate the effect of a mobile vehicle moving through the antenna's field. However if only the antenna is simulated the radiation pattern is centered around the antenna (as can be expected). If I add a reflector to the environment (a simple plate) the radiation pattern shows clear interference but has now shifted towards the plate.

Is this the default NEC method, or does the output plotter of SuperNEC perhaps have a bug in the sense that the results of the simulation are interpreted incorrectly?

Cheers
Slayer
