When running 1500 watts through a PL259, even after several minutes of
steady carrier (RTTY) the connector is barely warm.  I would estimate
the loss at less than a watt, if that much.  Ditto for the double
female connector.  That is so far below 1500 as to be inconsequential.
Don't worry about it.
