Abstract

A housing for a search-antenna polarization instrument is formed by two housing shells (2, 3) which are plugged together in an interlocking manner. A depression can be formed on the outside of the housing, as a positioning surface (12 to 16) for an alignment instrument. Furthermore, a direction-finding groove (19, 20, 21) can be formed on a housing wall. One housing wall may also have a respectively rising extremely profile on two opposite ones of its four side edges. This improves the direction-finding accuracy of a search-antenna polarization instrument.

Claims

1. Housing of a search-antenna polarization instrument, characterized by two housing shells (2, 3) which are plugged together in an interlocking manner, where the housing which is basically cuboid in shape has six housing walls (4 to 9),

each housing shell (2, 3) is formed by exactly three of the housing walls (4, 5, 6, 7, 8, 9),

each housing wall of a housing shell (2, 3) is integrally connected by two adjacent side edges, of its four side edges, to another housing wall,

the inner faces of adjacent housing walls (4 to 9) are arranged precisely at right angles to each other,

on the outside of one housing wall at least one ridge (26, 27) is formed for holding a coil as antenna counterweight, while an antenna may be located inside the housing,

on the outside of one or more housing walls there is, on each one, a depression formed which serves as a positioning surface (12 to 16) for an alignment instrument, and

a direction-finding groove (19, 20, 21) is formed on the outside of one housing wall or on several housing walls.

2. Housing according to claim 1, characterized in that the interlocking connection is formed by grooves (10) formed in the long edges of the housing walls and protruding longitudinal ridges (11) on complementary abutting surfaces.

3. Housing according to claim 1, characterized in that the interlocking connection is formed by ridges formed in the long edges of the housing walls and longitudinal grooves provided on complementary abutting surfaces.

4. Housing according to claim 1, characterized in that the housing shells (2, 3) are made of plastic.

5. Housing according to claim 1, characterized in that the positioning surface (12 to 16) is rectangular.

6. Housing according to claim 1, characterized in that the depression for the positioning surface (12 to 16) is not more than 1.5 mm in depth.

7. Housing according to claim 1, characterized in that the two positioning surfaces (12 to 16) are each located in pairs opposite each other.

8. Housing according to claim 1, characterized in that one positioning surface (14, 15, 16) runs transversely to a direction-finding groove (19, 20, 21) provided on the outside of the housing.

9. Housing according to claim 1, characterized in that one positioning surface (14, 15, 16) runs across a narrow side of the housing transversely to the longitudinal direction of this narrow side.

10. Housing according to claim 1, characterized in that the direction-finding groove (19, 20, 21) runs along a central longitudinal axis of a housing wall.

11. Housing according to claim 1, characterized in that direction-finding grooves (19, 20, 21) are provided on three narrow sides of the housing.

12. Housing according to claim 1, characterized in that one housing wall (14, 15, 16) has an external profile rising at an angle with respect to two opposite edges of its four side edges.

13. Housing according to claim 12, characterized in that a direction-finding groove (19, 20, 21) is arranged between two sloping sections of the outside wall (5a, 5b, 8a, 8b, 9a, 9b) which rise to the parallel side edges, being set at a lower level relative to them.

14. Housing according to claim 1, characterized in that operating elements are arranged on one of the wide sides of the housing and a threaded opening (24) is located on one lower side of the housing (1).

15. Search-antenna polarization instrument, including:

a housing (1) according to claim 1, an antenna located in the housing (1), and

a coil serving as antenna counterweight (28), which is held on the outside of the housing (1) by at least one ridge.
