[QUOTE="davidcmadrid, post: 859258, member: 390700"] This is correct , and the lobes and nulls seem sharper with this antenna type with the sharpest lobe being focussed on the UK. They have done some pretty advanced director work for the new series of antennas as they are not smooth ( but subtly dimpled ) surfaces. A side effect of how well they focus the primary lobe is the almost apparent randomness but ultimate sharp dropoff of the side lobes. Remember all energy going into the transmission array will result in a better saturation of the target area if they can " mangle " the sidelobes into being small and pronounced. As for 2E and similarities with 2F, i have little experience but for me its a waiting game to play the " Astra lottery " either the sidelobes will be kind to me as with 2F or they wont :) [/QUOTE]
