CAUTION
Semiflex cable has a minimum bending radius, specified by the
manufacturer. Bending it too sharply will damage the cable. See
Table 1
for the various sizes.
CAUTION
Stressing a coax connection after assembly can detune the sys-
tem. Therefore, never make a connection and then bend or twist
the cable.
Likewise, do not use the connector and flange to force the coax
into shape. Form the coax to the desired shape before attaching it
and align the connection properly, then make the connection.
