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?

Explicación

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.
