How does the performance of a horizontally polarized antenna mounted on the side of a hill compare with the same antenna mounted on flat ground?

  1. The main lobe takeoff angle increases in the downhill direction
  2. The main lobe takeoff angle decreases in the downhill direction
  3. The horizontal beamwidth decreases in the downhill direction
  4. The horizontal beamwidth increases in the uphill direction
