I'm new to antennas, so I'm still learning. I've been messing around with a program called 4nec2 and MultiNEC. I'm trying to understand the readout for the pattern magnitude.
I have this picture:
I noticed on the dBi scale that the level goes up to 7.53 dBi. Does this mean that the signal strength at that location is more than what was inputted? If so, is this due to constructive interference?
