And even then it wouldn't work, because the receive side of the duplexer
(connected where a reject load would normally be) doesn't provide a good
match at the Tx frequency, so the isolator ends up providing no isolation
(i.e. the isolator will no longer be the ideal 50 ohm virtual load that you
were hoping for).
