Radiation pattern? - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

Hey all,

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?

Thanks!
