yagi antennas

hi all,

just bought a pair of 2.4GHz Yagis, and as I understand, they consist of a driven element, and a lot of passive elements. my question is, how close would 2 of these have to be to start to interfere with each other?

thanks in advance.

i think maybe that would depend on their gain dbi and maybe they would have to be perfectly parallel to each other so they dont cross.....im not sure though,just a thought....

hi,

thanks for your reply, they are 20db, I am just looking for a really general answer not necessarily a measurement. i only ask because it will be more effort and cost to mount them so they don't interfere with each other (if indeed they would at all)

thanks again
