DEFINITIONS of TERMS
IN USE BY THE ARLHS
ACTIVATION, ACTIVATING A LIGHT:
Placing a radio station at, on, or within a light and establishing communication with another entity.
The radio station must be a legally recognized and licensed entity, not necessarily an amateur radio station, however. If the station is not physically on or within the light, it must qualify under the “Visual Sight Rule,” defined elsewhere in the ARLHS rules.
BASE:
That foundation or physical man-made structure upon which the beacon rests.
This does not include the natural earth or rock formation surrounding the light,
but is rather limited to that material specially man-made, manufactured, and constructed
as the foundation, deliberately placed into position to support the light. It is considered to
be an integral part of the light itself and is indistinguishable from it.
LIGHT, LIGHTHOUSE, LIGHT STATON,
LIGHTSHIP, LIGHT TOWER, and BEACON:
For the purposes of the ARLHS, these terms shall be considered
synonymous and include, but are not limited to, the following:
*Light: a light intended primarily as a nautical navigational aid.
*Lighthouse: a light tower in the form of an enclosed building or a light tower
mounted on top of an enclosed building.
*Light station: a government facility including a light tower and keeper's quarters.
*Lightship: a maritime vessel, either on the high seas or docked, whose primary purpose
was or is to support a nautical navigational beacon of some type.
*Light tower: any fixed structure displaying a light as an aid to navigation.
*Beacon: a light intended primarily as a nautical navigational aid.
HISTORIC:
The term "HISTORIC" refers to a light that no longer exists.
It may have been destroyed by nature or by man, or it may have been moved to another location,
in which case the new location is given a new and different ARLHS number, and the old location
and its old number are labeled as "Historic" or "Hist." See definition of "MUSEUM" below.
MUSEUM:
A MUSEUM lighthouse or lightship is a light that has been moved and converted to a museum for
display and has NOT been recommissioned as an active aid to navigation.
The original location of the museum light will be kept on the ARLHS list or added to the
ARLHS list, if not already there, as an "HISTORIC" light. See definition of "HISTORIC" above.
MARITIME MOBILE, MARINE MOBILE:
*Maritime Mobile: a radio station aboard a nautical vessel located on the high seas.
*Marine Mobile: a radio station located aboard a nautical vessel, either in motion or docked,
on an inland body of water or one within the continental limits of a sovereign nation or DXCC entity.
NOTE: Both of these are also referred to as /MM or “Mickey Mouse Mobile.”
