RX antenna - 2el end-fire beverage array antenna

B I U S link image code list	Show page   Syntax
!Applications If you are after improved directivity in the rear of the antenna (improving the DMF), you can put up two Beverages fed as an end-fire phased array.The Beverages you wish to phase together need to be identical (same height and length). In an end-fire Beverage array it is important that the two elements have a similar F/B, as you are going to subtract the signals from both elements. You only get zero if you subtract two identical numbers. It does not matter what the numbers are though. Two Beverages with a 10-dB F/B can produce 30 to 40-dB nulls in an array, just as much as a pair where the individual elements already show 25 dB F/B.
