operated on 28.3 MHz, at which each of the four sides (or legs, in rhormbic talk) is now 2A long. Here, I closed down the angle at the feed from 45° on each side of axis (90 ° total for a square), to 35 for a 2A leg length. The desired lobe to the right in Fig 22-16 is the result of cument run ning from the source towards the far end. The lobe to the rear results from current reflected from the far end returning towards the source. You can reduce the rearward lobe by termi- nating the end of the antenna with a sistance that equals the characteris- tic impedance of the antenna system.
