Apparatus and related methods for serially and removably connecting a plurality of electrical fixtures. An exemplary apparatus includes a connector housing having a mounting surface, a first set of electrical contacts positioned, at least in part, in the connector housing, a second set of electrical contacts positioned, at least in part, in the connector housing, and a plurality of conductive member extending from the first set of electrical contacts to the second set of electrical contacts, such that a first electrical fixture removably connected to the first set of electrical contacts is in serial electrical communication with a second electrical fixture removably connected to the second set of electrical contacts.

Systems and methods for connector enabling vertical removal

The object of this invention is to reduce the adverse system performance effects resulting from antenna pattern sidelobes. It has particular application to the time reference scanning beam of the international microwave landing system (MLS) where sidelobe energy reflecting into the mainbeam at the receiver antenna introduces a timing measurement error. It also has application to systems such as height finding radar where signals entering through antenna pattern sidelobes degrade system performance. This invention describes methods and apparatus for system performance enhancement through the application of sidelobe amplitude and phase control.

Scanning antenna having multipath resistance

The object of this invention is to reduce the adverse effects of reflected electromagnetic radiation on the measurement threshold of a scanning beam. It has particular application to the time reference scanning beam of the international microwave landing system (MLS). In the present MLS configuration, the reflection induced errors during the 'TO' scan are additive to those of the 'FRO' scan. This invention describes a method and apparatus for compensating errors by reversing the phase of the reflections during the 'FRO' scan, by displacing the phase center of the transmitantenna during that scan. System performance is enhanced by the errors compensation.
