摘要： Methods for locating noise in a CATV system are disclosed. The methods may use a probe or instrument configured to be coupled to a port of the CATV system. The probe may be operable to selectively filter signals in the CATV system to suppress the frequencies at which noise may be present in the CATV system. In some embodiments, the methods may also use a signal level meter, and the probe may be configured to be coupled to the signal level meter to detect and locate noise in the CATV system.

摘要： An example mount may include a strap (or any other type of clamping mechanism) engaging with an external surface of an antenna. The strap may be connected to a strap base with a canted wall also engaging with the external surface of the antenna. The engagement of the canted wall may be through an abutment of the canted wall against the corresponding external surface of the antenna at a single point or along a single line. Because the entirety of the canted wall does not have to be flush with the corresponding external surface of the antenna, the mount can couple to any kind of antenna form factor, such as curved antennas and antennas with imperfections and protrusions.

摘要： A global navigation satellite system (GNSS) antenna alignment device may have two movably attached arms to a main housing of the antenna alignment device. Each arm may have a GNSS antenna mounted thereon. The baseline between the GNSS antennas is therefore tri-segmented, with a first arm forming a first segment, a second arm forming a second segment, and the main housing forming a third segment. The length and orientation of the baseline may be adjusted by moving one or more of the first arm and the second arm. Furthermore, the first arm and the second arm may be stowed for a convenient storage and transport.
