What are the equations for a phased antenna array due to: 1. Individual element gain and the number of elements 2. Aperture of the array I have been googling these for god knows how long and can't find the slightest hint, except the site Microwaves 101 (http://www.microwaves101.com/), which left out the f-ing equation I described in number one. I am building a phased array radio telescope for the UHF band (out of TV antennas) and am in dire need of these equations. Thanks, ls.
