Larry has done some very nice work here, which I've used by adding cable 
to those connectors -- one pair to connect the cable to the source, and 
a second pair for connection to a load.

The only thing I changed in Larry's connector model is the loss in the 
section of transmission line that describes the connector to a value I 
believe is much more realistic for conductors the size of a mated pair 
of UHF connectors.

Looking at this, I don't see a need for compensation.
