Open circuit quarter wave or short circuit half wave coax stub and was it at the the input of the masthead amp or the input of the TV ?

You best have low expectations of resolving any TVI with such low signal levels and TV set front end and IF gains near maximum. The ACMA would most likely tell you that the local translators are the only source that should be utilised, the same as happened on the Gold Coast (SE Qld) when the Mt Tamborine UHF TV translators came on line.
