2x7-Element |
2x7-Element-Yagi stacked in vertical configuration
The stacking distance is 3,00m for a compromize between gain and pattern. With 3,20m you have a little bit more gain, but greater sidelobes. |
Stacking scheme: L1 and L2 are pieces of 75-Ohm-coax with a length of 5/4-lambda or 7/4-lambda * V (velocity of propagation). V=0,667 with full-PE cable (e.g. RG-59BU), V=0,81 with foam-PE (e.g. CATV-cable). |
