   This method is the wrong method.  As recommend by the ARRL and others,
It is best to not fan out the shield, but cut it about ¼" past the 
jacket and tin
the shield  into copper tube, then screw the connector on to the cable, 
threaded
onto the jacket and solder through the FOUR holes from the connector to the
tinned shield.  A pencil tip flame propane torch can be used, if very 
careful use
is involved.

   When I began as a broadcast engineer in 1963 every video cable had a
PL259 on each end of sections of RG-11/U and dependability was job #1.
                                                               75Ω
