Ok, I can understand where u r comming from with the reflection theory but let me get a little more specific. I can (at most of these locations) hook up a different manufacturer and mdel tv right off the same outlet with the tvs in question and it will program and work just fine. I am now to the point (after making sure the parameters on the EH24 are correct with Drake tech. support and making sure that the trunk, feeder and install is acceptable) that I'm thinking that some of these el cheapo digital tvs that flood the market have very poorly constructed tuners that are very sensitive.
