سؤال 110

When using a directional antenna, how might your station be able to communicate with a distant repeater if buildings or obstructions are blocking the direct line of sight path?

  1. Change from vertical to horizontal polarization
  2. Try to find a path that reflects signals to the repeaterپاسخ درست
  3. Try the long path
  4. Increase the antenna SWR

توضیح

VHF and UHF signals reflect well off buildings, hillsides and other large conductive or dense surfaces, so a beam antenna can be aimed away from the repeater at a reflecting object and still reach it. Changing polarization or raising SWR does nothing about the obstruction.
