An antenna assembly for receiving television signals on both very high frequency (VHF) bands and ultra high frequency (UHF) bands, the antenna assembly including: a main section including an elongated boom, at least one active element coupled to the boom, and at least one passive element coupled to the boom; a VHF section including a VHF boom configured to be coupled to a first longitudinal end of the boom and at least one active element coupled to the VHF boom; and a UHF section including a UHF boom configured to be coupled to a second longitudinal end of the boom opposite the first longitudinal end and a plurality of passive elements coupled to the UHF boom.

An example smart antenna mount may couple an antenna alignment device with an antenna. The smart antenna mount may include sensors such as strain gauges and accelerometers, and an electronic circuitry to communicate the measurements from the sensors. The measurements are received by the antenna alignment device, which may perform further operations to determine whether the coupling is within desired bounds. If within desired bounds, the antenna alignment device may generate an indication of a normal coupling, e.g., by activating a first colored (e.g., green) LED. If the coupling is outside the desired bounds, the antenna alignment device may indicate an alarm condition, e.g., activating a second colored (e.g., red) LED or generating an audible signal.

An antenna housing is provided that is configured to be mounted to a pole. The antenna housing has spaced upper and lower ends. A sidewall extends between and around the spaced ends to define an interior of the housing. This interior may house and/or partially conceal one or more antennas. Inlet and outlet ducting extend through the sidewall of the housing to individually cool each antenna within the interior of the housing. The inlet and outlet duct may connect to a cooling duct that is in fluid communication with a heat rejection surface of the antenna. Accordingly, each antenna may be cooled using ambient air and the heated air may be exhausted outside of the housing.

A low-PIM dual pipe clamp and associated mounting bracket for securing a first pipe transverse to a second pipe at a cellular base station antenna site. The dual pipe clamp accommodates a range of pipe diameters with lower PIM generation, cost, and weight characteristics compared to conventional dual pipe clamps traditionally used at cell sites. The low-PIM dual pipe clamp minimizes the number of parts to upper and lower mounting brackets connected by linear threaded rod connectors, such as bolts, avoiding the use of U-bolts known to create PIM interference in conventional designs. The dual pipe clamp secures first and second pipes against each other in transverse orientations (e.g., horizontal and vertical), as typically utilized to mount antennas at cellular base stations. Each mounting bracket includes first and second pipe restrainers that bias the first and second pipes against each other as the threaded rod connectors are tightened.

Exemplary methods for making an extension assembly include marking on a ¾″ conduit a line 2 feet from one end, inserting the marked end of the ¾″ conduit into a 1″ conduit until about 9″ of the ¾″ conduit is exposed, and without putting on a nut, assembling one 1⅜″ ID U-bolt onto the ¾″ conduit at a point the ¾″ conduit enters the 1″ conduit.

The present invention provides target devices such as filter units with a plurality of external projection members that project outwardly from the target device and cooperate with apertures in a mounting bracket whereby the target device can be slidably moved from a first position to a second position provided by a lobe of the apertures to couple the target device to a respective support structure using a respective mounting bracket. The mounting bracket can be provided as a plurality of mounting brackets, including a first one attached to the support structure and a first side of a first target device and a second one attached to a second side of the first target device and to a first side of a second target device thereby allowing the first and second target devices to be stacked together to a common support structure.
