: adapter with a newly fabricated one. The new
: adapter did not introduce noticeable changes in
: the horizontal position: any differences, if
: they exist, should be below the millimeter. In
: the vertical, the ARP of the new antenna is 13.4
: mm below the old ARP, as a consequence the
: antenna height is changed.
