   en.wikipedia.org/wiki/Trough_(meteorology)

   A lee trough, also known as a dynamic trough, is "A pressure trough formed on the lee side of a mountain range in situations where the wind is blowing with a substantial component across the mountain ridge; often seen on United States weather maps east of the Rocky Mountains, and sometimes east of the Appalachians, where it is less pronounced."

3. Lee wave - Wikipedia

   en.wikipedia.org/wiki/Lee_wave

   They always occur in groups on the lee side of the terrain that triggers them. Sometimes, mountain waves can help to enhance precipitation amounts downwind of mountain ranges. [5] Usually a turbulent vortex, with its axis of rotation parallel to the mountain range, is generated around the first trough; this is called a rotor.

4. Windward and leeward - Wikipedia

   en.wikipedia.org/wiki/Windward_and_leeward

   The leeward side is the side distant from or physically in the lee of the prevailing wind, and typically the drier. In an archipelago windward islands are upwind and leeward islands are downwind of the prevailing winds, such as the trade winds of the Atlantic and Pacific oceans.

5. Sidelobes - Wikipedia

   en.wikipedia.org/wiki/Sidelobes

   In antenna engineering, sidelobes are the lobes (local maxima) of the far field radiation pattern of an antenna or other radiation source, that are not the main lobe.. The radiation pattern of most antennas shows a pattern of "lobes" at various angles, directions where the radiated signal strength reaches a maximum, separated by "nulls", angles at which the radiated signal strength falls to zero.

6. Offset dish antenna - Wikipedia

   en.wikipedia.org/wiki/Offset_dish_antenna

   Main types of parabolic antennas. An offset dish antenna or off-axis dish antenna is a type of parabolic antenna.It is so called because the antenna feed is offset to the side of the reflector, in contrast to the common "front-feed" parabolic antenna where the feed antenna is suspended in front of the dish, on its axis.

"Lee" historically means "shelter". Standing on the leeward side of the vessel, a sailor observes being blown towards an exposed shoreline by the wind.

9. List of RF connector types - Wikipedia

   en.wikipedia.org/wiki/List_of_RF_connector_types

   NMO mount connector (new Motorola mount), removable mobile antenna connector uses a 3 ⁄ 4 inch (19 mm) mounting hole and has a large base with a 1 1/8" – 18 tpi thread for attaching the antenna. SC connector, screw version of C connector [not to be confused with the fiber optic connector of the same name]
