The lenses preferably have a continuous cross section along a vertical axis. A mounting system can also be used for mounting the lens over phased array antenna. The mounting system can comprise a housing piece and a retaining ring for holding the lens over phased array antenna. ## Claims ### Claim 1 An aggregation node for an access network, comprising: two phased array antennas operating at different polarizations; two changeable cylindrical lenses for the two phased array antennas to modify a sweep arc in azimuth allowing a radiation pattern to be adapted for an installation location, wherein the two changeable cylindrical lenses comprise a first changeable cylindrical lens for a first phased array of the two phased arrays antennas, a second changeable cylindrical lens for a second phased array of the two phased arrays antennas; and an alignment system for rotationally aligning the changeable cylindrical lenses to their respective phased array antennas. ### Claim 2 (depends on 1) The aggregation node as claimed in claim 1, wherein at least one of the phased array antennas comprises several columnar radiating elements. ### Claim 3 (depends on 1) The aggregation node as claimed in claim 1, wherein at least one of the changeable cylindrical lenses has a continuous cross section along a vertical axis. ### Claim 4 (depends on 1) The aggregation node as claimed in claim 1, wherein at least one of the changeable cylindrical lenses is a plano convex lens. ### Claim 5 (depends on 1) The aggregation node as claimed in claim 1, wherein at least one of the changeable cylindrical lenses is a plano concave lens. ### Claim 6 (depends on 1) The aggregation node as claimed in claim 1, further comprising an antenna and lens mounting system for mounting at least one of the changeable cylindrical lenses over the at least one of the phased array antennas. ### Claim 7 (depends on 6) The aggregation node as claimed in claim 6, wherein the antenna and lens mounting system comprises a housing piece and a retaining ring for holding the changeable cylindrical lenses over the phased array antennas. ### Claim 8 (depends on 7) The aggregation node as claimed in claim 7, further comprising at least one gasket between the housing piece and the retaining ring. ### Claim 9 (depends on 7) The aggregation node as claimed in claim 7, further comprising an antenna printed circuit board on which at least one of the phased array antennas is implemented, the antenna printed circuit board being held by the housing piece. ### Claim 10 (depends on 9) The aggregation node as claimed in claim 9, the alignment system rotationally aligning the antenna printed circuit board to the first changeable cylindrical lens. ### Claim 11 A method for configuring an aggregation node for an access network, comprising: establishing wireless internet service provider handoffs to endpoint nodes with two phased array antennas comprising a first phased array antenna and a second phased array antenna, the first and second phased array antennas operating at different polarizations, wherein a first changeable cylindrical lens is for the first phased array antenna, and a second changeable cylindrical lens is for the second phased array antenna; adapting a sweep arc of the phased array antennas, the changeable cylindrical lenses associated with the phased array antennas allowing a radiation patterns to be adapted in azimuth for an installation location; and for each phased array antenna, rotationally aligning the corresponding changeable cylindrical lens to the phased array antenna. ### Claim 12 (depends on 11) The method as claimed in claim 11, wherein at least one phased array antenna comprises several columnar radiating elements. ### Claim 13 (depends on 11) The method as claimed in claim 11, wherein one of the changeable cylindrical lenses has a continuous cross section along a vertical axis. ### Claim 14 (depends on 11) The method as claimed in claim 11, wherein at least one of the changeable cylindrical lenses is at least one of: a plano convex lens, and a plano concave lens. ### Claim 15 (depends on 1) The aggregation node as claimed in claim 1, wherein both the first and second changeable cylindrical lenses are mounted on a common lens substrate. ### Claim 16 (depends on 15) The aggregation node as claimed in claim 15, further comprising a housing, wherein the common lens substrate comprises at least one indexing bore for mating with at least one indexing shoulder of the housing to preserve rotation alignment of the changeable cylindrical lenses with the phased arrays antennas. ### Claim 17 (depends on 1) The aggregation node as claimed in claim 1, wherein the alignment system is a snap-in system.
