Abstract: A remote radio head assembly attaches a remote radio head to the back wall of an antenna unit. The remote radio head assembly has a radio bracket attached to the top of the radio head having a handle for lifting and carrying the radio head. Radio guide spacers attached to the back side of the remote radio head are for sliding the remote radio head along a mounting rail attachment disposed on the back wall of the antenna unit. The mounting rail has a pivot hook for receiving an installation lever configured to engage with the handle to move the remote radio head in downward and upward directions so as to couple the connector ports of the antenna unit.

Abstract: A coaxial cavity resonator filter has a hollow cavity and a post having desired dimensions for achieving desired filter characteristics. A tuning element is supported within a metallic opening and is configured to electromagnetically interact with the post. The tuning element has a conductive core element where the orientation of the tuning element with the cavity is adjusted so as to achieve the desired filter characteristic. An insulator is configured to cover a portion of the conductive core element of the tuning element, at a location where the tuning element and the metallic opening interact. A portion of the insulator is threaded so as to allow the conductive core element vary its orientation within the cavity without contacting the metallic opening.
