Abstract:
The present invention provides a linear motor (1) having a forward mode and a backward mode. The linear motor (1) comprises: a reciprocating unit (20) arranged to be moved in a forward direction (FW) and in a backward direction (BW), and a thrust unit (30) arranged, in the forward mode, to move in a forward direction (FW) in response to the reciprocating unit (20) moving in the forward direction (FW) and, in the backward mode, to move in a backward direction (BW) opposed to the forward direction (FW) in response to the reciprocating unit (20) moving in the backward direction (BW).
Abstract:
The present invention provides an antenna holder 301 for engaging with a RRU holder 302 and vice versa. The antenna holder 301 comprises a guiding part 305 and a receiving part 304, wherein the guiding part 305 is configured to receive and guide a protruding part 307 of the RRU holder 302 to the receiving part 304, and wherein the receiving part 304 is configured to receive the protruding part 307 of the RRU holder 302 in an engagement position of the two holders 301 and 302. The present invention also provides a method for mounting an RRU 402 with an RRU holder 302 to an antenna 401 with an antenna holder 301.
