Interesting Tom but it doesn´t adress what I wrote under this subject. Guess somehow things got mixed up.

power is carried in the feedline. In an ideal system, you'd have the reactance at the antenna, so that the feedline is at 50 ohms, and all the box needs to do is generate the right phases. Of course, the matching network at the antenna would then need to have multiple values, since the feedpoint impedance changes with the array steering direction. And, it would be quite "challenging" to tune up (broadcast antenna engineers earn their pennies doing this).>>
