Because of this the IF A samplers in these four antennas
(ea12, ea15, ea22 and ea28) are being underdriven by about
2 dB.  As a result they will appear about half as "good" as
other antennas on the fringe display.  This will persist until
the samplers are replaced again and should not be considerd
a cause to write up the antennas as broken.
